The Evaluation of Germplasms with Resistance to Fusariumwilt and verticillium wilt from Shaanxi cotton section

Abstract: Cotton germplasms from Shaanxi cotton section, with resistance to fusarium wilt and verticillium wilt, and mealtimes with high yield, excellent quality and tolerance for drought, were one of earliest resistant materials in china, After many of them, such as Shaan mian 4, Shaan mian 5, Shaan mian401, Shaan mian5245 and Shaan mian1155 and so on, were used by lots of others breeding units, more sixty famous varieties for example, Jin mian7, Ji mian14, 86-1, chuan mian56, Su mian5, Xin Lu zhong3, zhong17, zhong19, zhong23, zhong35 and zhong41, were bred, Germ plasms from Shaanxi cotton section and some varieties originating from them, which had covered 2×107hm2, had great effort on fusarium wilt and verticillium wilt. There by germplasms from Shaanxi cotton section as resistance materials were of great application value.
