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。
According to the principle of mixed linear model, the yield traits of late rice in Zhejiang Province from 1994 to 1995 were used as the data. Based on the statistical analysis of the unbalanced data of regional trials of crop cultivars proposed by Zhu Jun et al., The variance components of yield traits and Stability parameters of the tested varieties. The results showed that the location effect was the main factor affecting the yield. The effect of year × site interaction had a great effect on yield, effective panicles, solid grains per panicle and 1000-grain weight. The highest yield was C 10 6 7, while Jia 5 5 was insensitive to the environmental index and showed good consistency. In addition, a linear comparison was made between the yield traits of the cultivars in different regions.
