摘要：

大豆耐旱性是重要的农艺性状，直接影响大豆产量，近年来有关报道不断增多。此研究以‘红丰11’为轮回亲本、Clark为供体亲本构建回交群体进行耐旱性鉴定及叶片持水能力QTL定位。利用单向方差分析法检测到8个QTL位点分布于A1、B1、C2、E、L和N 6条连锁群，其中Satt316、Satt457和Satt694位点贡献率较高，可能是控制大豆耐旱性的重要位点。

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.
