Abstract

In this study,a set of recombinant inbred lines(RILs) population derived from Kefeng 1 and Nannong 1138-2 was used to analysis the inheritance model of salt tolerance,and to detect quantitative trait loci(QTL) associated with salt tolerance during seedling growth in soybean.Inheritance of salt tolerance in the RIL population was investigated by the mixed major gene plus polygene inheritance model of quantitative traits.The results showed that salt tolerance of soybean was controlled by three major genes(the F-3 model).Heritability value of the major gene was 64.4%.We also performed QTL mapping for plant survival days(PSD) responsive to salt stress in soybean.Three QTLs were detected on B1、G and K linkage groups,which explained total phenotypic variance of 8.4%,17.9% and 11.3% respectively.
