Construction of a genetic map and QTL mapping of seed size traits in soybean.

ABSTRACT: Soybean seed size and seed shape traits are closely related to plant yield and appearance quality. In this study, 186 individual plants of the F₂ generation derived from crosses between Changjiang Chun 2 and JiYu 166 were selected as the mapping population to construct a molecular genetic linkage map, and the phenotypic data of hundred-grain weight, seed length, seed width, and seed length-to-width ratio of soybean under three generations of F₂ single plants and F_2:3 and F_2:4 lines were combined to detect the QTL (quantitative trait loci) for the corresponding traits by ICIM mapping. A soybean genetic map containing 455 markers with an average distance of 6.15 cM and a total length of 2799.2 cM was obtained. Forty-nine QTLs related to the hundred
