【Abstract】 This paper analyzed the parent mating, the using of resistant resources, mating way and the breeding method of seven varieties with resistance to soybean cercospora sojina developed in 1986-1994. The results showed that the key of breeding disease resistant varieties was reasonable selected resistant resources, fully using the resistant soybean resources from overseas and disease resistant materials from domestic. At the same time, we have proved that one time intercross and selecting continuously, backcross breeding and the combination of inercross and radiation were the effective ways of breeding resistance to cercopora sojina.更多还原
