过去曾利用我们已发现的WBY、WBY—1、LKBY等几个大豆雄性不育系进行杂交组合的组配工作,取得了某些进展。然而,由于这几个隐性单基因控制的高度雄性不育系msms纯合个体的雄性不育性难以保持,而且它们的雌性能育性很差,这就给利用带来了很大的困难。所以创造、发现和研究新的雄性不育系就显得更为重要。 通过杂交和诱变相结合的育种手段,1987年在一个诱变的M_2代株系中发现了一个育性发生分离的群体。这个M_2代株系共有91个单株,在收获期据单株结荚数的多少,可
In the past we used some of the soybean male sterility lines we have found such as WBY, WBY-1 and LKBY to carry out the combination work of the crosses and made some progress. However, since the male sterility of the msMS homozygous individuals of the highly male-sterile male sterility lines controlled by these recessive single genes are difficult to maintain and their female fertility is poor, this poses great difficulties for utilization . So creating, discovering and researching new male sterility lines is even more important. Through a combination of breeding and mutagenesis, a fertile segregating population was found in a mutagenized M 2 generation in 1987. The M_2 generation of plants a total of 91 individual plants, at harvest, according to the number of pods per plant, may
