Résumé (dcterms:abstract)
-
The selection of new hybrid varieties of interspecific bananas with traits of resistance to pests and diseases is essential for the development of agroecological banana systems without pesticides. Such breeding is based on the combined use of the parents of Musa acuminata and M. balbisiana. Unfortunately, infectious alleles of endogenous sequences of the Banana streak virus (eBSV) are present in the genome of M. balbisiana’s progenitors.
In this work, we show that M. balbisiana diploid spawners available for reproduction host at least one infectious eBSV. We also show how we separated infectious and non-infectious eBSV alleles from M. balbisiana diploids by self-pollination or chromosomal doubling of haploid lineages.
