High-density QTL mapping of leaf-related traits and chlorophyll content in three soybean RIL populations

摘要

Phenotypic variation in leaf size and shape among parents and progeny in three RIL mapping populations. The female parents, Williams 82, Enrei and Bogao had a leaf length/width ratio of ~ 1.5, while the male parents, Dongnong50 (DN50), Suinong 14 (SN14) and Nannong 94–156 (NN94156) had a ratio of ~ 3.0. The segregating progeny exhibit transgressive segregation in leaf length/width ratio, as this ratio ranged from about 0.95 to 4.32
