沈农雄性核不育大豆L—78—387是我国首次发现的大豆雄性不育材料。测验研究表明:同一个 ms1位点上,有5个独立的突变体,为扩大利用雄性核不育基因于轮回选择的育种实践创造了更为有利的条件。如果优良品系或具有特殊目标性状的材料携带上 ms1不育基因,再去进行自由授粉随机互交,就可以使雄性核不育基因成为轮回选择的得力工具。对进一步研究未发现的连锁群也具有一定意义。但是,由于大豆为自花授粉作物,异交率极低,其花粉较重,不能借助风力传粉。因此,目前利用 ms 搞大规模制种尚存在不少问题。 Shennong male sterile soybean L-78-387 is the first discovery of soybean male sterility material in our country. Tests showed that there were 5 independent mutants at the same ms1 locus, which created more favorable conditions for expanding the practice of breeding using male sterile gene in cycle selection. If elite lines or materials with special target traits carry ms1 sterile genes and then randomly cross-fertilize with random pollination, the male sterile gene can become an effective tool for the cycle selection. For further research has not found linkage group also has some significance. However, since soybean is a self-pollinating crop, the rate of outcrossing is extremely low and its pollen is heavy and can not be pollinated by wind. Therefore, the current use of large-scale seed production there are still many problems.
