Triploid citrus breeding at Cirad

To progress on the understanding of chromosome composition and segregation of the breeding material used to improve plantain bananas, we performed several analysis based on

A clear understanding of the meiotic mechanisms producing the diploid gametes (unreduced from diploid parents and reduced from tetraploid parents) and

Using this second approach, SDR has been identified as the restitution mechanism leading to unreduced gamete formation in a wide range of mandarin genotypes used as female

Aiming to offer a larger number of commercial varieties with different harvest periods, more than 200 accessions of mandarins present in the Germoplasm Bank, and more than 200

In Spain we are carrying a triploid breeding program since 1996 based on 2x X 2x, 2x X 4x and 4x X 2x pollinations followed by embryo rescue and flow cytometry, and the use

QTL-mapping was notably applied to the analysis of genetic determinism of SALB resistance sources in Wickham x Amazonian families (CMB = Cirad-Michelin-Brazil project), and

Mechanism of 2n gametes formation and its implication on parental heterozygosity restitution, as weIl as the male parent heterozygosity and parental differentiations, are the

Yield reduction occurs in “ “ super super ” ” rice when inputs rice when inputs are not high.. are
