【Abstract】 Using the method of nonparametric statistics,the productivity and the stability of 9 peanut cultivars are studied . The results show that Zheng 86036 26 1 is the cultivar with good productivity and good stability, P i and P′ i in the method are good productivity indexes and S i is a good stability index. The method is simple,direct and practical and is fitted to evaluate new cultivars in regional experiments.更多还原
