以3204S、HN5S、8906S、安湘S、113S和9451S等6个籼型核不育系为材料,在武昌自然条件下,对其育性转换特性进行了观察研究。结果表明:除9451S外,其余5个不育系在7~8月不育性是比较稳定的;6个核不育系,9月份都有一个时段出现了一定比率的深染色花粉,育性转换明显;平均自交结实率均低于30%。
Six indica genic male sterile lines, 3204S, HN5S, 8906S, Anxiang S, 113S and 9451S, were used as materials to study their fertility traits under natural conditions in Wuchang. The results showed that except for 9451S, the other five CMS lines were stable from July to August. Six lines of male sterile line had a certain ratio of deep-dyeing pollen in one period in September. Fertility Conversion significantly; the average self-seeding rate of less than 30%.
