GCIRC and GCIRC Congress

The Groupe Consultatif International de Recherche sur le Colza (GCIRC), with its office at 12, avenue George V, 75008 Paris, France, was established to encourage scientific and technical research concerning the improvement of rapeseed and its processed products from the agronomic, technological and foods perspectives, and to encourage collaboration among researchers. The organization has no political activity.

The GCIRC is managed by the Board of Directors elected by 70 subscribing members from more than twenty countries.

The secretary of the GCIRC is Mr. André Pouzet, CETIOM, with office support of Mrs. Laurencine Lot. Professor Fu Tingdong, Huazhong Agricultural University, Wuhan 430070, China is the current GCIRC President.

The GCIRC International Rapeseed Congress is held every four years with GCIRC Technical Meetings between two major events. Staring from 1987, GCIRC issues an award on its every congress to honor scientists who have made significant contributions to one of the areas in rapeseed research. So far there are six scientists having received the honor: Dr. Baldur R.

Stefansson (Canada, 1987), Prof. FU Tingdong (China, 1991), Dr. R. Keith DOWNEY (Canada, 1995), Dr. Jacques MORICE (France, 1995), Dr. Gerhard RÖBBELEN (Germany, 1999), Dr. Jan KRZYMANSKI(Poland, 2003).

The 12th International Rapeseed Congress, with the theme of “Sustainable Development in Cruciferous Oilseed Crops Production” is held in Wuhan, China, March 26-30, 2007. The congress consists of a program with the following seven sections: Genetics and Breeding, Biotechnology, Agronomy, Plant Protection, Quality, Nutrition and Processing, Feed and Industrial Raw Materials, and Trading and Policies. Each of these sections is divided into oral and poster presentations. In addition, the congress also hosts 8 workshops covering a range of topics.

The contributions from oral presentations and posters are included in books of Abstracts and Proceedings with the full papers, and an electronic disc.

On the occasion of the 20 anniversary of the founding and awarding of the Eminent Scientist Award by GCIRC, Ministry

of Agriculture of the People’s Republic of China will grant an honored certificate to all the awardees ever on this congress.

Welcome Address by the President at the Opening Ceremony of the 12 th International Rapeseed Congress

Good morning ladies and gentlemen,

On behalf of GCIRC, the Advisory Committee, the Organizing Committee, the Scientific Committee, the International Scientific Committee of the 12

th

International Rapeseed Congress and all the staff members of the Congress, it is a great honor for me at this significant moment to extend our warmest welcome to the friends and participants from all over the world. I would like to take the opportunity to express our gratitude to the Ministry of Agriculture of the People’s Republic of China, Hubei Provincial Government, Wuhan Municipal Government, the Chinese Academy of Engineering and all the other supporters. My gratitude also goes to the enterprises that have sponsored the Congress.

2007 is the year of the 20

th

anniversary of the GCIRC Eminent Scientist Award, which is a particular honor for the distinguished scientists in rapeseed research field. Six scientists so far have won the prize. Today, in addition to myself, we are privileged to have Dr. K. Downey, Dr. G. Röbbelen, Dr. J. Krzymanski presented on the Congress. I would like to express our warmest welcome to them.

As you all know, China is the country with the largest rapeseed planting area, which is about 7 million hectares, with 11 million tons of production annually, of which 85% are produced in Yangtze River Basin. Rapeseed yield in China accounts for 30% of the world’s total production. Hubei, located in the middle of the Yangtze River Basin, is the largest rapeseed production province. Two major rapeseed research institutes in China, Huazhong Agricultural University and the Oil Crop Research Institute of Chinese Academy of Agricultural Sciences, and the National Research Center of Rapeseed Engineering Technology, jointly-run by the two institutes, are located in Wuhan, the capital city of Hubei province. I believe that the 12

th

International Rapeseed Congress will have a great impact on both rapeseed production and the research in China, particularly in Hubei Province. It is hopeful that the Congress will be a very good occasion for all our participants to discuss, communicate and learn from each other in the field of rapeseed research and production.

In retrospect, the history of rapeseed development has witnessed significant achievements of rapeseed research in the past 30 years. Scientists all over the world have contributed jointly to the development in quality improvement, hybrid vigor, resistance breeding, biotechnology, cultivation physiology etc. Rapeseed is not only an edible oil crop, a fertilizing crop, or a honey crop, but also a major promising biodiesel crop, which brings about new opportunities for rapeseed production and research. The GCIRC has been the active force in promoting the exchange, the dissemination and the utilization of the achievements.

The theme of this Congress is “The Sustainable Development in Cruciferous Oilseed Crops Production”. Seven Hundred abstracts related to the theme have been submitted and more than 700 scholars are attending the Congress, which demonstrates your solicitude, support and wish for the 12

th

International Rapeseed Congress held in Asia for the first time. I am convinced that the 12

th

International Rapeseed Congress will be worth your trust.

To end my speech, I wish every participant a pleasant stay in Wuhan, and the Congress a brilliant success. Thank you.

Abstract

University of Manitoba canola/rapeseed breeding programs have always focused on improving seed quality with increases in oil, protein and sum of oil and protein, reduction in fibre and oil composition modifications targeted. Genomics has recently been added to the wide range of techniques used at the UM to develop high seed quality canola/rapeseed.

Key words: oil, protein, oil composition modifications, fibre, canola, rapeseed

Canola/rapeseed is the major oilseed crop grown in Canada. In addition to continued improvements of agronomic performance, steady improvements in the seed quality of canola/rapeseed varieties are required to maintain the competitive edge of Brassica varieties compared to other oilseeds. Seed quality in canola/rapeseed is multi-faceted, consisting mainly of oil, protein, glucosinolates and fibre levels in the seed and oil composition.

The University of Manitoba (UM) canola/rapeseed breeding programs monitor and select for oil and protein levels and for the sum of oil and protein levels in the seed. The maximum oil, protein and sum of oil protein contents in B. napus observed in yield trials in recent years at the UM are shown in Table 1. All of these materials possess black seeds. Compared to the checks, it appears that oil level in black seeded B. napus lines can be increased by approximately 5%, protein level by over 1% and the sum of oil and protein level by over 7% in black seeded lines and likely by even more in yellow seeded lines.

Molecular marker assisted selection for increased oil concentration using the Sequence Related Amplified Polymorphism (SRAP) marker system (Li and Quiros 2001) has begun recently at the UM. Large DH line populations are being developed and evaluated for oil level variation currently.

Reduced fibre content in canola/rapeseed is a function of seed coat thickness, which is seed-coat-colour related. The yellow seed coat colour trait in Brassica significantly reduces fibre content. UM research and development on yellow seeded canola/rapeseed currently focuses on the development of SRAP molecular markers for the genes conferring the yellow seed coat trait in Brassica rapa and Brassica napus.

Oil composition modification research continues to be a focus of the UM Brassica breeding programs. Reduction in saturate level has been pursued using microspore mutagenesis, intraspecific crosses within B. rapa and B. napus, interspecific crosses and DH line production from the BC1F

1

plants of these crosses (McVetty and Scarth, 2002). Low saturated fat DH B.

rapa lines from the cultivar Reward were created using microspore mutagenesis at the Plant Biotechnology Institute at

(22)

Saskatoon, SK. These mutant DH lines were crossed to normal DH lines from the cultivar Reward and then DH lines produced from the F

1

plants. These B. rapa DH lines were then crossed to selected B. napus genotypes which were low in saturated fat levels to create interspecific F

1

’s. The production of DH lines from the interspecific F

1

’s was difficult, so a backcross to the B. napus genotypes was done. Selection for low saturate level within the high stability oil (HSO) B. napus materials developed at the UM was also done. The saturated fat levels achieved in selected materials developed in this research are shown in Table 2.

The reduction in linolenic fatty acid level with resulting increases in oleic level in canola oil types, has been a long term breeding objective at the UM (McVetty and Scarth 2002). The initial focus was on the reduction of linolenic acid, using the M11 mutant line from Rakow (1973), with the cultivars Stellar (1987), Apollo (1993) and Allons (1994), having 3%, 1.7%

and 2.5% linolenic acid, respectively, released by the UM. Linolenic acid level in B. napus is controlled by two genetic loci with additive effect. These loci have been co-located to two fad3 genes in B. napus by genetic mapping. Minor genes, maternal and cytoplasmic effects have also been associated with the variation in the linolenic level in B. napus. As a result, linolenic acid level generally shows continuous variation in crosses between high and low linolenic lines. The complete elimination of linolenic acid from the seed oil is not likely to be achieved by conventional breeding, as linolenic acid plays an essential role for normal plant growth and reproduction.

Oleic acid concentration in Stellar, Apollo and Allons ranged from 60 to 66%. Comparative studies showed that oils with relatively higher oleic and lower linolenic levels than conventional canola oil possess an improved oxidative stability without the requirement of partial hydrogenation, and produce less undesirable products during deep frying (Warner and Mounts 1993).

Mid to high oleic acid oils have equivalent heat stability to saturated fats and are suitable replacements for them in commercial food service applications that require long life stability. The profile of the optimum high stability oil (HSO) based on these comparisons has a 67 to 75% oleic acid level compared to conventional canola cultivars with about 61% oleic acid in the seed oil. The low linolenic canola breeding program at the UM has placed increasing emphasis on oleic acid concentration in addition to linolenic acid concentration, to create HSO materials. The minimum linolenic acid % and maximum oleic acid % in these HSO materials are shown in Table 3.

The development of industrial end use high erucic acid rapeseed (HEAR) varieties with increased erucic acid level has

been a major breeding objective at the UM. A Swedish origin rapeseed with high erucic acid level was crossed to Tower to

create the first HEAR variety, Reston (1982). A number of HEAR cultivars have been released by the UM after Reston

including Hero (1989), Mercury (1992), Neptune (1995), Venus (1995), Castor, (1996), Millennium 01 (1998), Millennium 02

(23)

(1999) and Millennium 03 (1999). More recently, two new Roundup Ready HEAR cultivars, Red River 1826 (2006) and Red River 1852 (2006) have been released. Erucic acid level in B. napus is controlled by two genetic loci with additive effect.

Minor genes have also been associated with variation in erucic acid level so that erucic acid level shows near continuous variation from zero to over 60% in canola×HEAR crosses. Erucic acid level has increased from 45% in Reston to 55% in the MillenniUM series HEAR cultivars. The Roundup Ready Red River HEAR cultivars have an erucic acid concentration of approximately 53%. The lower level of erucic acid in the Red River HEAR varieties is a minor gene effect not related to the Roundup Ready gene or to Roundup tolerance. The maximum erucic acid level of HEAR varieties grown at the UM in recent years are shown in Table 4.

The development of super high erucic acid rapeseed (SHEAR) germplasm with erucic acid levels of greater than 66% is also an important rapeseed breeding objective at the UM. This goal has been approached by re-synthesizing B. napus through crossing selected lines of the two ancestral diploids, B. rapa and B. oleracea, which can incorporate C22:1 into the Sn-2 position, (Taylor et al. 1995), followed by chromosome doubling. Re-synthesized B. napus plants accumulate levels of C22:1 over 60%. SHEAR development is currently being pursued using two approaches, 1) in-house microspore mutagenesis of resynthesized B. napus lines and 2) fatty acid biosynthesis transgene pyramiding in collaboration with the Plant Biotechnology Institute. The PBI transgenes affect fatty acid biosynthesis pathways and influence erucic acid levels in the oil. The maximum erucic acid concentrations observed in the SHEAR materials are closely approaching the theoretical upper limit of 66% erucic acid (Table 5).

The preservation of seed quality through incorporation of disease resistance is another important breeding objective, with SRAP molecular marker assisted disease resistance gene pyramiding research and development in progress. Molecular markers for several blackleg disease resistance genes will soon be available for use in the UM canola/rapeseed breeding programs.

Recent breeding efforts involve the development of herbicide tolerant canola/rapeseed cultivars and the development of hybrid canola/rapeseed cultivars. The UM has developed several canola varieties using the OXY gene conferring tolerance to the herbicide bromoxynil, including Armor BX (2000), Cartier BX (2000), 295 BX (2000), Zodiac BX (2000) and Renegade BX (2001).

Hybrid canola/rapeseed variety development is increasingly important at the UM with parental line combinations which maintain or enhance seed quality in the hybrids being identified.

Abstract

Field experiment conducted for two years indicated that the seven CMS lines of Brassica juncea differed for stigma receptivity. Stigma receptivity was recorded up to 10 days in Ogura, Moricandia and Erucoides systems. Peak stigma receptivity was observed two to three days after flower opening in case of Siifolia, Erucoides and Moricandia (green). It was suggested that Ogura and Moricandia (green) could be useful for hybrid development and seed production.

Key words: CMS lines, Brassica juncea, stigma receptivity, artificial pollination

Development of hybrids in field crops lead to higher productivity and production in field crops. Use of male sterility system is one of the means to develop hybrids. Heterosis in Brassica spp. is a well-known phenomenon (Labana et al., 1975;

Banga and Labana, 1983; Anand, 1987; Pradhan et al., 1993). A number of cytoplasmic male sterility (CMS) systems have been developed in B. juncea (Rawat and Anand, 1979; Prakash, 2001). Identification of fertility restorer is another pre- requisite. However, use of CMS lines for hybrid seed production depends upon the production potential of CMS lines in a specific heterotic cross combination.

Brassica juncea, a major oil crop in India, is predominantly self-pollinated in nature. Insects mainly (honey bees) act as pollen vectors effecting pollination to a great extent. Stigma receptivity is important for out crossing, fertilization and hybrid seed production. Stigma of B. juncea, in general, becomes receptive 3 days prior to its opening and remain receptive up to 3 days after opening of flower (Rai, 1991). A longer period of stigma receptivity of CMS line is desirable for higher seed production. Little information is available in this respect. Therefore, a study was made to understand duration of receptivity of stigma of CMS lines of Indian mustard and the results are presented in this paper.

Materials and Method

Seven CMS lines of B. juncea in Pusa Bold (PB) background were grown in winter season of 2001-2, and 2002-3 in the field of Indian Agricultural Research Institute, New Delhi. Pusa Bold plants were grown along with the CMS lines as pollen parent. Male sterility plants of CMS lines were identified and tagged. Unopened flower buds likely to open in the inflorescence were covered with butter paper bag. Open flower and immature buds were removed. Flowers were pollinated manually from the day it opened. Pollination were done up to 8 days in 2001–2 on different sets of flowers already covered before opening with fresh pollen of PB. The pollinated flowers were covered after pollination. After observing the result of 2001-02, pollination was extended for two more days i.e., upto 10 days in 2002-03. A similar set was kept for this study under open pollination in 2002-03. The experiment was conducted on 5-10 inflorescence with 5-15 developed buds in each inflorescence of the CMS lines in peak flowering period. Data were recorded on number of pods set with seeds per siliquae on the pollinated flowers of each CMS line.

Results and discussion

There was a reduction of siliquae setting and development up to 8 days from flower opening in all the CMS lines. The number of siliquae with seed declined drastically with an increase in flower age before pollination (Table1).

Oxyrrhina CMS showed maximum percent siliquae set even after 8 days of flower opening indicating a longer period of

(25)

stigma receptivity. A reduction in number of seeds set per siliquae was recorded with increased flower age also. Two to four seeds per siliquae were recorded in all the CMS lines except in Tournefortii on 8

th

day after flower opening (Table 2).

In the flowering year, the study was extended up to 10 days in both open pollination and artificial pollination situations.

The result indicated slight reduction of pod setting up to 6 days in most of the CMS lines except Moricandia (chlorotic) and Tournefortii (Table3). Tournefortii has deformed style and stigmatic surface. Oxyrrhina,Ogura, Moricandia (green) and Moricandia (chlorotic) showed one seed per siliquae when pollinated artificially with pollens of PB on 10

day (Table 4).

Tournefortii had the lowest number of seeds per siliquae even on the 1

A critical observation of data on number of seeds per siliquae obtained after pollination indicated that maximum number of seeds were set on 2nd day after flower opening in siifolia and Erucoides while on 2nd and 3rd day in Moricandia (green). In Moricandia a prolonged period of stigma receptivity up to 6 days was recorded giving 8 seeds/ siliquae (Table-4). This indicated the peak stigma receptivity in these three CMS lines could be 2-3 days after flower opening.

The CMS lines possessing longer duration of stigma receptivity is useful for higher seed production. In our study a difference in per cent seed set under controlled condition compared to open pollination among CMS lines was observed. The CMS lines differed to produce at least 50 per cent seed per pod compared to its potential after an interval of flower opening under open pollination. Erucoides had longer duration (8 days) compared to Ogura and Moricandia (chlorotic) (7 days) and Moricandia (green)(6days). In Oxyrrhina lower than 50 % seed set was recorded after 4 days of flower opening (table 4).

Therefore, Erucoides, Ogura and Moricandia would be desirable for hybrid seed production.

Maximum stigma receptivity in B. juncea was reported to be one day before the opening of flower (Labana and Banga, 1984). Difference in stigma receptivity could be due to genetic reasons. Maximum stigma receptivity in CMS lines of B.

juncea was recorded one day before anthesis. It declined gradually till 3-5 days and drastically thereafter. However, stigma remained receptive for 6-8 days after anthesis (Mankar, 2000). He also observed a difference in stigma receptivity in CMS lines. Oxyrrhina and Siifolia had lower stigma receptivity (up to 6 days) as compared to that of Tournefortii (up to 8 days).

Thus, it can be concluded that on the basis of stigma receptivity and its favourable effects on the period of seed set and its

number the CMS lines, namely Ogura and Moricandia (green) could be used successfully for hybrid development.

Abstract

With the success of Ogu-INRA CMS system, the focus of breeding efforts in oilseed rape has shifted decisively towards hybrid breeding. Delineation of germplasm into heterotic gene pools is important as complementation between divergent parents is known to define limits of heterosis. In this communication we present results of our attempts to measure genetic diversity in Indian and Australian B. napus germplasm (36) on the basis of variation for twelve morphophysiological traits. Diversity analysis (UPGMA) categorized the test germplasm into five groups with overall dissimilarity coefficient of 0.59 suggesting a narrow genetic base. Group I comprised 13 Australian genotypes with dissimilarity coefficient of 0.30. Group II comprised seven Australian canola, six Indian canola and two Indian non-canola types. Two Australian (Monty and BST-7-2M

2

) and one Indian non-canola type were included in Group III. Trilogy was the lone genotype in Group IV, close to Group V comprising two Indian canola types GSC 302 and OCN 3, besides an Australian genotype Tranby. Based on genetic diversity, three sets of hybrids (95) were developed by crossing selected Australian lines as female with Canadian (Ashai), Indian canola (OCN 3 and GSC 5) and Indian non-canola (GSL 1 and Neelam) cultivars as males. These hybrids were evaluated against GSC 5 as a frequent check to estimate standard heterosis. Average heterosis in these three sets respectively, was 0.6, 19.8 and 37.5 per cent, suggesting, in general, an association of standard heterosis with diversity in the test germplasm evaluated. Two canola (Rivette×OCN 3 and Av- Sapphire×GSC 5), and six canola×non-canola combinations (AG-Spectrum×GSL 1, Oscar×Neelam, AV-Sapphire×GSL 1, Surpass 400×Neelam, Monty×Neelam and Oscar×GSL 1) were highly productive.

Key words: Oilseed rape, genetic diversity, heterosis, canola, hybrids.

Introduction

Heterosis, a major force during crop evolution, has proved rewarding for productivity enhancement in a large number of field and vegetable crops. Quantitative genetic explanation for this phenomenon depends directly on existence of dominance and indirectly through interaction involving dominance effect at different loci in hybrids. Assuming heterosis as a function of heterozygosity, it can be considered as a function of parental diversity. Geographic diversity, singly or in combination with other measures of genetic diversity like combining ability analysis has been used in the past to assess parental diversity (Tsaftaris 1995). In spite of the past inconsistent results, documentation of diversity and its association with hybrid performance is critical since it helps in limiting the number of germplasm lines for evaluation in test hybrid combinations. In this communication an attempt has been made to assess genetic diversity in 36 B. napus germplasm lines of Indian and Australian origin, using multivariate analysis. In addition, linking hybrid performance of a fairly large number of F

combinations with divergence patterns in the germplasm was attempted.

Material and Methods

Experimental material comprised self bred genotypes of B. napus, originating from India and Australia, along with a set of 95 hand bred F

combinations. The F

combinations were developed on the basis of geographic diversity by crossing Australian lines as females with Canadian (Ashai), Indian canola (GSC 5 and OCN 3) and Indian non canola (GSL 1 and Neelam) lines as males. Parental lines and the hybrids (along with commercial check varieties) were raised separately as paired row in a balanced block design with two replications at row to row spacing of 45cm and plant to plant spacing of 10- 15cm. Standard agronomic practices were followed throughout the crop season. Data were recorded for ten random plants per genotype/F

in each replication and averaged for key morpho-physiological characteristics including yield and its components.

Statistical analysis for morphological data was conducted using the software programme NTSYS pc version 2.02e (Rholf 1998). Cluster analysis was conducted on the taxonomic distance matrix with the unweighted pair group method based Arithmetic average (UPGMA). A dendrogram was generated based on genetic distance matrix. Heterosis was estimated as increase or decrease in the mean performance of hybrid over commercial pure line, GSC 5, expressed as per cent.

Results

Mean data for twelve morpho-physiological traits of the parents was subjected to diversity analysis which partitioned the
