Shengdong Huang

Abstract

The photoperiod sensitive genic male sterile line 1023S(japonica rice) was bred through the hybridization between N95076S(female parent) and C418(male parent).The characteristics of 1023S were studied through the time sowing test and related indexes investigation.The results showed that 1023S had stable fertility,its pollen abortion was complete,and its sterile plant rate and sterile degree all reached 100%.It had good flowering habit,high stigma exsertion rate,high seed yield in seed production,strong combining ability and strong resistance to stripe virus disease.
