山东省小麦新品种(系)高产稳产性分析

采用高稳系数法(HSC),结合变异系数和稳定性参数,对2001—2002年度山东省高肥小麦新品种(系)区域试验的l3个品种(系),进行了高产稳产性综合评价。结果表明:烟475、烟农23是两个聚合了高产稳产基因型的优良小麦新品种,潍62036具有一定的高产潜力,但稳产性稍差。3种分析方法得出的结论基本一致,高稳系数法是一种简便而有效的评价作物高产稳产性的方法。

The High Yield Stability Analysis of New Wheat Varieties in Shandong Province

Using the high stability coefficient, coefficient of variation and stability parameter judged productivity and stability of 13 new varieties of the 2001-2002''s higher soil fertility group in wheat variety area test of Shandong. The results revealed that Yan 475, Yannong 23 were the best new wheat varieties that converged genotypes of productivity and stability; Wei 62036 had definite high yield potential, but stability was worse slightly. The conclusions derived from the three methods were similar substantially. HSC is a simple and effective method that judged crop''s productivity and stability.
