1971年,我参加了县种子站为寻找小麦不育株专门召开的会议。从此,我们科研小组便开展了这项工作。当年,找到了十几株小麦不育株,但是,到1972年观察,却全部恢复自交结实。大家分析失败原因,认为上年找到的不育株,又瘦又小,可能是受外界条件影响所致。所以我就专门找与上年不同的小麦不育株。我把五百亩大田麦地几乎找遍了,也没有找到一株与上年 In 1971, I participated in a special meeting of county seed stations in search of wheat sterile plants. Since then, our research team carried out this work. In those days, more than a dozen strains of wheat were found. However, by 1972, they all recovered self-fertility. We analyze the reasons for the failure, that the sterile strains found last year, thin and small, may be affected by external conditions. So I specifically look for different wheat strains from the previous year. I am almost five hundred acres of field cornfield looking over, did not find a strain with the previous year
