Abstract: Eberhart-Rusell's method on the Stabiliby Analysis of Yield and Mandel's mthod on the partitioning of interaction in Analysis of Variance beve been used to analyze the data about 7-Maize hybrids in 1990 and 6-Maize hybrids which weere all planted in 18 diflerent locations in Sichuan province, respectively. The results indicate as follows. 1. G×E is an important factor of affeeting yield of those hybrids. G×E effect with e_i has a linear relationship in most situations, but sometimes there is nonlonear relationship between them. 2. "Chuan-Long Single cross 9" not only has higher yield, bus also is the most stable on yield as well as in the all hybrids. Therefore, it can plant in all the experenced area. The resal's also demonstrate that estimated value based on Mandel-model is fit well in with the observed vale from the eaperiment. So, It should be used widely in analysing G×E interaction. The biological basis of the stability on "Chuan-Long Single cross 9" has also been discussed in the last part this paper.
