Assessment of efficiency of breeding methods using molecular markers in soybean

Four breeding methods viz. pedigree method (PM), single pod descent (SPD), with selection (SPDS) and bulk (BM) were compared for maintaining variability in the population advanced generations using simple sequence repeats (SSR) markers. The F4:7 lines through different from six crosses evaluated number of unique retained each at a similarity coefficient ? 0.875. Eighteen polymorphic SSR markers used estimating between within cross. In all crosses, SPD was best producing range 42.9 to 100 per cent. had also least pairing two or more lines. PM BM three maximum proportion produced by these paired four Thus, most efficient among retaining population, but breeder has make choice high comparative harvest seed processing efficiencies select suitable method.
