1971年,我们在湖南黔阳农校经验启发下开始水稻雄性不育,杂种优势利用试验研究。1972年冬引入红芒野生稻花粉败育株(简称野败),1975年育成一批粳稻野败不育系。1974年冬从新疆引入粳661～1,在测交同时做了恢复系转育和株系选择。1975年实现粳稻野败三系配套,1977年筛选到8个恢复度超过80％的恢复株系,其配合力和杂种优势正在测配鉴定中。
In 1971, we started the experiment of rice male sterility and heterosis utilizing the experience of Guizhou Qiyang Agricultural School. The introduction of Hongmang wild rice in the winter of 1972 pollen abortion (referred to as wild defeat), in 1975 bred a group of japonica wild sterile line. In the winter of 1974, japonica 661-1 was introduced from Xinjiang. At the same time, the restorer lines were transferred and the lines selected. In 1975, the three lines of japonica wild catches were matched. In 1977, eight restorer lines with more than 80% of the recovery degree were screened, and its combining ability and heterosis were being tested.
