| Abstract: | By using cotton dual-purpose line 473A with male sterile gene ms14 , Shanmian 9 with resistance to fusarium wilt and CCRI 12 with resistance to fusarium and verticillium wilts, genetic male sterile dual-purpose line kangA 1 and kangA 2 by means of crossing transference and bidirectional selection to fertile plants and sterile plants in both disease nursery and field were conducted in from 1978 untill now. The inheritance of resistance, combining alility of resistance and lint yield and utilization of kangA 1 and kangA 2 were studied. Till now, using kangA 1 and kangA 2 as sterile lines 3 hybrids were selected and used in the production. |
