河北省夏玉米品种基因型与环境互作综合分析

Comprehensive Analysis of Genotype × Environment Interactions of Summer Maize Cultivars in Hebei Province

利用AMMI模型和GGE双标图,对2015年河北省夏播玉米区域试验中13个参试品种在10个试点的相关农艺性状进行分析,包括子粒产量、穗长和千粒重。结果表明,各农艺性状在不同基因型和环境间存在极显著差异,基因型和环境间存在极显著互作效应。参试品种丰产性表现较好的有龙华369、J1302、衡玉1182,丰产性表现较差的有澳玉698、JF33。衡玉1182、J1302、荃玉18、郑单958和龙华369品种稳定性表现较好,鑫研218稳定性最差。丰产性、稳产性和适应性较好的品种有J1302、衡玉1182和龙华369。

An additive main effects and multiplicative interaction(AMMI) model and a genotype main effect and genotype and environment interaction(GGE) biplot were used to analyze the related agronomic traits of 13 tested maize cultivars at 10 test sites during the regional trial in Hebei province, including grain yield, ear length and 1000-kernel weight. The results showed that there were significant differences in agronomic traits between genotypes and the environments, and there was a significant interaction between genotypes and environment. The yield performances of Longhua369, J1302, and Hengyu1182 were higher than others. Whereas, cultivars Aoyu698 and JF33 had the lowest yield performance. The cultivars Hengyu1182, J1302, Quanyu18, Zhengdan958 and Longhua369 were more stable than others, and Xinyan218 had the lowest stability among all cultivars. According to comprehensive analysis, the cultivars J1302, Hengyu1182, and Longhua369 were better in yield performance, stability and adaptability.
