7个小麦品种(系)高产稳产性分析

Analysis of High-and Stable-Yielding Ability of Seven New Wheat Varieties(Lines)

采用高稳系数法(HSC),结合变异系数和稳定性参数对2004～2005年山东省高肥小麦新品种区域试验的7个品种(系)进行高产稳产性综合评价。结果表明:烟2415的平均产量、增产点率、适应度、高稳系数均最高,地域变异和变异系数最小,是一个适应性良好的丰产稳产品种。三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。

Using the high stability coefficient （HSC）, variation coefficient and stability parameters, the high - and stable - yielding ability of seven new wheat varieties （lines） of the high - fertility regional test group in 2004 -2005 in Shandong Province was evaluated. The results showed that Yan 2415 was a high - and stable -yielding variety with good adaptation, which had the highest average yield, yield increasing points, adaptation degree and high stability coefficient, and also the smallest geographic variation and variation coefficient. The conclusion derived from the three methods was basically identical. HSC is a simple and effective method for evaluating crop＇ s high - and stable - yielding ability.
