粳稻区域试验非平衡数据产量性状及稳定性分析

Analysis of Yield Characters and Stability for Unbalanced Data in Japonic Rice Regional Trial

根据混合线性模型的原理 ,以 1994～ 1995年浙江省晚稻区域试验的产量性状为资料 ,运用朱军等提出的作物品种区域试验非平衡资料的统计分析方法 ,分析了产量性状的各项方差分量及参试品种的稳定性参数。结果表明 :地点效应是影响产量的主要因素 :年份×地点互作效应对产量、有效穗、每穗实粒、千粒重都有较大影响。以丙 10 6 7产量最高 ,嘉 5 5对环境指数的反应不敏感 ,表现一致性较好。此外 ,对不同地区选育的品种产量性状进行了线性对比。

Variance components and the stability performance of yield characters were analyszed for Japonic rice in the year of 1994 and 1995 in Zhejiang regional trial with the methods by Zhu Jun et al. The results showed that loction effect was the main factor for yield. The yield, effective panicles, full filled grains and 1000-grain weight were mainly affected by year×location interaction. The yield of Bin 1067 was the highest. Jia 55 was not sensitive,basides,the rice which came from different breeding units were compared.
