In accordance with the cabbage variety development trend, relying on the existing breeding technology, will improve the winter, increase the yield, enhance disease resistance breeding of a new spring cabbage as winter portfolio standard. The paper studies the new combination of 0807 breeding process, effects of different treatments on the seed setting rate of pollination, Brassica tissue culture technology, and the improving method and cabbage seed production of F1 pollution-free cultivation techniques.1 new combinations of 0807 cabbage breedingSelection of cabbage breeding materials suitable for breeding, get in line with the requirements of the self incompatible lines, the distribution group, screening, product ratio, breeding of high yield, strong disease resistance, winter is strong, high quality and more in winter and spring cabbage 0807 new combination.2 Effect of different treatments on the seed setting rate of cabbage combination 0807 pollinationSpraying 5% NaCl solution can significantly improve the flowering cabbage seed setting rate, spraying 0.2% potassium dihydrogen phosphate and 0.2% borax and 0.2% zinc sulfate could significantly improve the self incompatible lines of seed setting rate, improve the seed quality.3 Study of new combinations of 0807 cabbage seed stem tip tissue culture breeding systemSeedling survival rate was 95%, tissue culture breeding yield is higher than conventional breeding methods of tissue culture of 39.8%, parent offspring strong life, high germination rate, seedling progenies of strong growth potential.4 Effect of different treatments on seed production of cabbage 0807 new combinationPlastic film mulch species and strains to strain rate is 2%, frostbite strain rate was 4%, death rate reduced by 60% strains of root international banking, frostbite strain rate reduced by 71.4%, plant green fast, good growth. Plastic film mulching of susceptible number as 60% reduction in root soil, reduce mortality was 50%, seed yield than international up to about 22.8% higher; topping can make the plant flowering 9 days in advance, flowering by 9 days; cut the ball can make the plant flowering 5 days in advance. 5 cabbage without planting techniques of pollution GAPUsing the principles of HACCP, starting from the key link is more in winter and spring cabbage seeding, seedling, planting, field management, harvesting, transportation, develop new cabbage 0807 regulation of non pollution Cultivation Techniques with high yield of GAP.
