摘 要 ：在人工控制条件下研究了在15小时长光照下减数分裂期的不同温度（23.3-30.3℃）对籼稻光敏不育系W6154S和5460S育性转换的影响。结果表明，温度对育性的影响因温度的高低及处理持续时间长短而异，不同的材料对温度的反应不同。5460S从不育的临界温度在26.4℃左右，而W6154S在处理温度范围内均出现自交结实现象，表明供试的W61

Abstract:Effect of temperature(daily average air temperature 23.3℃-30.3℃) at meiosis on the fertility of PGMS indica strains, W6154S and 5460S, was studied under controlled conditions. The results indicated that the effect was different with different temperatures and durations, as well as with different P
