Very little detailed information is currently available on the mechanisms of character transmission in banana. Breeding is thus still carried out using a traditional phenotypic approach based mainly on analyses to find interesting complementary traits derived from parents in different genomic configurations. For over 15 years, CIRAD has been developing an original strategy geared towards obtaining new triploid varieties from natural or improved fertil diploids. A high number of progeny can thus be obtained (contrary to standard crossing strategies with current varieties that are mainly sterile), thus enabling selection and genetic analysis of characters. New banana genetic improvement strategies based on genetic mapping and analysis of genetic factors determining traits of agronomic interest are being developed to overcome issues that hamper current improvement methods. One of tha main problems concerns the presence of structural heterozygosity between homologous chromosomes (due to chromosome anomalies that occur during meiosis, i.e. so-called translocations) as well as the lack of knowledge on their impact on character transmission. The "banana cartogenetic mapping" project aims to determine the mechanisms underlying translocations from a formal genetics standpoint, and to ultimately transfer the research results for the benefit of banana breeders. |
