摘要
以具有超高产水平的两系杂交稻 6 5 396 (培矮 6 4 s× E32 )为研究对象 ,在分析母本不育系培矮 6 4 s用作单季稻区域制种时的稳定不育期的季节和持续期的基础上 ,用生育期模型分析了培矮 6 4 s与 E32在南方一季稻区制种时的播差期及其变化规律。研究得到的两系法杂交稻制种技术的气象学方法可供其他熟制地区应用。
In terms of a developmental model, a super high yielding two line hybrid rice 65396 (AP64SE32) has been investigated both on steady sterile season and duration of its female parent AP64S and on sowing time difference between its female and male parents for seed production in a single rice cropping zone in the south of China. The agrometeorological technique for making hybrid rice seeds is applicable to zones of other rice cropping systems.
