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。
The two-line hybrid rice 6 5 396 (Pei’ai 64s × E32) with super high yield was used as the research object to analyze the effect of Maize sterile line Pei’ai 64s on the stable sterile period Based on the seasons and duration, the sowing period and its variation of Pei’ai 64s and E32 in the first season rice planting area in the south of China were analyzed. The meteorological methods of the two-line hybrid rice seed production technology obtained from the study can be applied to other cooked areas.
