Marker-assisted selection strategy to pyramid two or more QTLs for quantitative trait-grain yield under drought.

ABSTRACT: BACKGROUND:Marker-assisted breeding will move forward from introgressing single/multiple genes governing a single trait to multiple genes governing multiple traits to combat emerging biotic and abiotic stresses related to climate change and to enhance rice productivity. MAS will need to address concerns about the population size needed to introgress together more than two genes/QTLs. In the present study, grain yield and genotypic data from different generations (F3 to F8) for five marker-assisted breeding programs were analyzed to understand the effectiveness of synergistic effect of phenotyping and genotyping in early generations on selection of better progenies. RESULTS:Based on class analysis of the QTL combinations, the identified superior QTL classes in F3/BC1F3/BC2F3 generations wit
