Abstract: A F2 population derived from N87-1(drought tolerant)×9526（drought sensitive ）was used to construct genetic map by 103 SSR(simple repeat sequence) markers(Fig.1). The primary root within soil , root dry weight and yield of 183 F3 family lines were evaluated under water stress (WS) and normal irrig
