The results show that,?CCRI 50 was best, because of its high yield and better quality, and short growth period, early maturity, the highest rate of per frost yield, but there were some shortcomings in other varieties, such us relatively lower per frost yield of CCRI 60, the poor fiber quality of ZM6302, late maturity and poor lint yield of Sikang 1. Overall, four varieties were more suitable for planting with direct sowing after rape harvest in the Yangtze Valley. But more important, the relationship should be coordinated and harmonious between variety, environment and cultivation measures, in order to overcome the disadvantages of cultivation system of rape cotton, ecological and climatic conditions, and to further explore the potenti
