| Abstract: | Used new technique of interspecific hybridization in Gossypium,ferile hybrids of G.hirsutum×G.sturtianum were obtained quickly.New variety of Qinyuan 4 was bred by two times back-cross and selecting and stabilized in the wilt land.Qinyuan 4 had the characteristics of high yield and good Quality and multi-adversity resistance.At the same time,six types of new germplasms were developed.All those materials were resistance to both fusarirrm and verticillium,each of them also had some other very f ine characters,such as good fibre,high fibre strength,big boll,high lint%,and drought resistance respectively.These new germplases all are the very valuable materials in the cotton breeding. |
