Introduction of resistant gene and production of high yielding materials resistant to soybean cyst nematode for summer soybean

A series of soybean germplasm and varieties such as Qihuang 25,Qichadou 1 and Qiheidou 2 resistant to soybean cyst nematode were bred by sex hybridization to introduce resistant gene,using Beijing Xiaoheidou and Haerbin Xiaoheidou resistant to soybean cyst nematode as the resistant parentsThen using these new resistant germplasm as parents,good materials such as 91724,93746,93747,93748 and so on with resistance to cyst nematode,high yield,good quality and growth period suitable in Shandong were bred. As a result,the key techniques to get soybean germplasm with resistance to cyst nematode and high yield was to select potential combinations in the early germinations, emphasisly breed and identify,and combine selection in disease field with resistance identification in pot with disease soil
