Abstract: According to the data of Hubei provincial regional experiment and productive administration of maize in southwest China, the performance of productivity, stability and adaptability of Huayu 11 was analysed by testing the average yield,variation coefficient, high yield effect value, high stability coefficient, standard deviation method. The results show that Huayu 11 possesses higher yield, more strong stability, wider adaptability, and suitable for planting in southwest China and other corresponding ecological areas.To gain cultivation technique of high yield of Huayu11, the factor of fertilizer amount（F） and density（M） was designed on five levels in this experiment. The scheme for getting yield of 15 993 kg/hm² was that plant density of 60 000 plants/hm²,750.0 kg/hm² of fertilizer as base fertilizer and 450 kg/hm² of urea for topdressing（seed fertilizer:panicle fertilizer=1:2）.

Key words: maize（Zea mays L. ）, Huayu11, productivity, stability, adaptability, fertilizer level, growing density, yield
