| Abstract:
Hetrosis is a foundamental factor in biological evolution. Man has used this knowledge for the past 200 years to develop new varieties. Today practical use of this knowledge is made by the agricultural industry. Corn and sorghum F1 gybrids wee earlier varieties developed. Hybrids have replaced conventional varieties in watermaelon production. Melon (Cucumis melo L.) hybrid prodcuction developed later. In Japan, hybrid varieties were developed earlier and are used widely. In the middle of the eighties, China also began to use gybrid varieties following the international trends in melon production. Inheritance law of the characteristics in melon is the theory basis in the cross breeding (heterosis use included) and more research work and study have done in this area. Basedon general principles of the hetrozygotic breeding, a local variety, the Hetal sweet melon, is used as the female parent in all combinations. The primary male parent is the Xinjiang thick rind melon. Other male parents from U.S.A., Japan and Gansu Province, China were also used. The study demonstrated that practical use of hetrosis in quantitative characteristics of melon has great potentialities. | |
