摘要
以 3 418S、X0 7S、3 99S、2 3 0 1S和培矮 64S(CK) 5个籼型光温敏核不育系为材料 ,1994～ 2 0 0 1年在合肥进行分期播栽试验 ,抽穗时观察其育性变化情况。研究结果表明 :历年籼型光温敏核不育系的稳定不育时段大致为 8月 10～ 2 5日 ,其相应的育性敏感安全时段约在 7月 2 5日～ 8月
In this paper, the 5 Indica P(T)GMS rice lines of 3418S, X07S, 399S, 2301S and Peiai64S(CK) were used as the materials. The bagged self-seed and the abortive pollen of them were studied by sowing on different dates from 1994 to 2001 in Hefei. The results showed that the steadily completely sterile period of them was about from the tenth to the twenty-fifth of August for many years. Their corresponding stage of the safely sensitive sterile fertility was about from the twenty-fifth of July to the fourteenth of August.
