据美国《作物科学》杂志1970年7—8月号介绍印度吉耳和阿南德的研究,提出利用遗传性雄性不育生产杂交小麦种子问题。在印度卢德喜阿纳旁遮普农业大学农场中,杂交谱系 S738的二代群体中,发现有部分雄性不育的植株。当用某些品种和不育植株杂交时,所得的杂种一代是可育的,对杂种二代植株进行套袋自交,鉴别出大量的雄性不育植株。经过第四代和第五代的鉴定,选出结实率分别为5%、35%和65%三部分的雄性不育植株进行研究。假定结实率为5%、35%和65%的

According to a report by the Crop Science magazine from July to August 1970 in India, Gilles and Anand proposed the use of hereditary male sterility to produce hybrid wheat seeds. In the second generation of the hybrid pedigree S738, a part of the male-sterile plants were found in the farm of Hihna Punjab Agricultural University in Lhuddha, India. When hybrids of some cultivars and sterile plants were used, the resulting hybrids were fertile and the selfing of bagged hybrids of the second generation of hybrids was carried out to identify a large number of male sterile plants. After the fourth generation and the fifth generation identification, the male sterile plants with the seed setting rate of 5%, 35% and 65% were selected. The seed set rates are assumed to be 5%, 35% and 65%
