糯玉米区域试验非平衡数据产量性状及稳定性分析

Analysis of yield traits and stabilities based on the unbalanced data for waxy corn combination in Zhejiang regional trials

对2005—2006年浙江省糯玉米区域试验中参试组合进行统计,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;科糯1号、美玉加甜糯8号组合产量较高,显著比对照品种苏玉糯1号高;浙花糯1号对环境指数反应不敏感,组合甜糯2005-1表现一致性较差,其余组合在稳定性方面表现相似。

The variance components and the stability performance of the yield traits were analyzed, based on the unbalanced data from the year of 2005 and 2006 in Zhejiang waxy com combination regional trials, by using the methods of Zhu Jun et al. The results showed that the yield was mainly affected by year × location interaction. The yields of Kenuo 1 and Meiyujiatiannuo 8 were higher in the experiments, they reached significant difference comparing with Shouyunou 1. There were no strong sensitive to the environmental index for Zhehuanuo 1, low identity for Tiannuo 2005-1 and similar stability for the other waxy com combinations.
