W9834S是以W6111S的衍生系I3S为母本,常规早稻金宝2号为父本杂交选育而成的早籼型温敏核不育系,2005年1月通过湖北省科技厅组织的技术鉴定。W9834S在武汉的完全不育期60 d以上,不育期间不育株率100%,花粉败育度100%,套袋自交不育度99.99%。株型较紧凑,叶片挺直,叶色绿,不育起点温度低(23℃左右)。柱头外露率高,配合力强,所配杂交早稻组合熟期早,米质较优,产量高。
W9834S is a early indica type thermo-sensitive genic male sterile line which is derived from W6111S derived line I3S as female parent and conventional early rice Jinbao No.2 as male parent. In January 2005, it passed the technical appraisal organized by Hubei Science and Technology Agency. W9834S was completely sterile for more than 60 days in Wuhan, infertility rate was 100%, pollen sterility was 100%, bagging self-fertility was 99.99%. Plant type compact, straight leaves, green leaves, starting point of low temperature of infertility (about 23 ℃). Stigma exposed high, with strong, early hybrid rice with early maturity, better quality rice, high yield.
