宿9604小麦新品种生态适应性综合分析

The Integrated Analysis of the Ecological Adaptability of New Wheat Variety-Su 9604

利用 1998和 1999年安徽省淮北片半冬性组区试资料 ,应用高稳系数法和灰色关联度分析方法 ,对宿 96 0 4等小麦新品种 (系 )的丰产性、稳产性及生态适应性进行分析。结果表明 :宿 96 0 4两年平均较对照周麦 9号增产 12 .10 % ,属于A级水平 ;两年b值分别为 0 .82 6 7和 1.0 2 2 6 ,高稳系数为 93.37%和 83 .2 2 % ,是一个丰产、稳产型品种 ;两年灰色关联度ri 分别为0 .86 3 1和 0 .90 81,均居第 2位 ,接近参考品种 ,具有广泛的生态适应性。并对宿 96 0 4丰产稳产的原因进行了探讨。

The characters of high and stable yield, and ecological adaptability of Su 9604 were analyzed with the method of index and gray relation analysis. The result indicated:that compared with check variety-Yangmei No.9, 12.10% of yield was increased by Su 9604, belonging to A level. B value was 0.8267 and 1.0226, the stable index was 93.37% and 83.22%, respectively, in the trial of 1998 and 1999. So, the variety was with the character of high and stable yield. The gray relation grade was 0.8631 and 0.9081 respectively, which was the second position. So, the variety was with the character of wide adaptability.
