Well, that sounds teasingly intriguing. Fortunately, we have a mole at the relevant symposium of the International Horticultural Congress in Brisbane. Here’s his brief report from the trenches:
Great talk also by Pierre Yves Teycheney, who together with his colleagues at CIRAD seems to have found a way to deal with the problem of the endogenous Banana Streak Virus that is embedded in the Musa B-genome. Since its discovery this virus had essentially brought to a halt CIRAD’s inter-specific hybrid breeding program, and prevented distribution of any hybrid materials that contained the B-genome. Luckily, an allelic difference was detected that renders the virus non-infectious, so researchers at CIRAD managed to develop B-genome materials (through traditional approaches but also doubled haploids) that are homozygous for the non-infections alleles and ‘voila!’ derived non-infectious material is now again flowing through CIRAD’s interspecific hybrid breeding program!
Keep it coming, people!
