摘　　要：长S来自普通野生稻与籼稻珍珠矮杂交后代。在自然条件下,长S表现为长日高温可育、低温不育,且育性转换明显。经等位性测验,长S与C815S、广占63S、株1S、湘陵628S及HD9802S的育性基因等位,而与HN5S、培矮64S的育性基因不等位。Chang S is a new rice thermosensitive genie male sterile （TGMS） line obtained from the offsprings of the hybrid between Oryza rufipogon and Zhenzhu＇ai （indica flee）. The fertility of Chang S is sterile under longer light duration with high temperature but fertile under lower temperature in field, and the conversion of the fertility is obvious. Fertile gene is allelic between Chang S and C815S, Guangzhan 63S, ZhulS, Xiangling 628S, HD9802S, but is nonallelic between Chang S and HN5S, Pe＇ai64S.
