甜玉米区域试验非平衡数据产量性状及稳定性分析

Analysis of Yield Character and Stability for Unbalanced Data in Sweet Corn Regional Trial

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,对2005～2006年浙江省甜玉米区域试验中参试组合资料分析了产量性状的各项方差分量及参试品种的稳定性系数。结果表明:年份×试点互作效应对产量影响较大;白甜(糯)1号、蜜脆678组合产量较高,显著高于对照品种超甜3号;奥甜8210、脆王对环境指数反应不敏感,组合HM30表现一致性较差,其余组合在稳定性方面表现相似。

Variance components and the stability performance of yield characters were analyzed for sweet corn in the year of 2005 and 2006 in Zhejiang regional trial with the methods by Zhu Jun et al. The results showed that the yield was mainly affected by year x location interaction. The yields of Baitian（nuo） No. 1, Micui678 were higher than those of the others. In those combinations, Aotian 8210, Cuiwang combinations were not sensitive to environmental composite indexes, HM30 showed low identity, and the other combinations showed similar stability.
