Abstract:

The drought tolerance of soybean was important agronomic traits affect yield. In recent years, the report about it was increasing. A primary backcross introgression soybean population was constructed by using ‘Hongfeng 11’ as recurrent parent and Clark as donor parent. After screening by drought stress, the QTL identification was conducted by one-way ANOVA (for single marker analysis, P<0.01) with sixty super selection population. Eight QTLs of WRC were found in A1, B1, C2, E, L and N linkage groups. The QTL at Satt316, Satt457 and Satt694 have higher contributions, which may be important to drought tolerance of soybean.
