本文对１９８６～１９９４年育成的合丰号大豆７个抗灰斑病品种的亲本选配，抗源利用，组配方式和育种方法进行了初步分析。明确了合理选择抗源，充分利用国外的抗灰斑病资源和国内的抗病中间材料是育成抗病品种的关键。同时，肯定了一次杂交连续选择，回交转育，杂交和辐射结合的方法，是抗灰斑病育种的有效方法。 In this paper, preliminary analysis was made on the selection of seven anti-gray spot varieties of Hefeng soybean cultivars from 1986 to 1994, the utilization of their sources, the ways of combination and the breeding methods. Clear the reasonable choice of resistance to take full advantage of foreign gray spot disease-resistant resources and the domestic disease-resistant intermediate material is the key to breeding resistant varieties. At the same time, affirming a hybridization of continuous selection, backcrossing, hybridization and radiation combination of methods, is an effective method of breeding against gray leaf spot.
