摘要
利用AMMI（主效可加互作乘积）模型及双标图、Di（品种稳定性参数）以及相应表现型值与Di值的聚类分析,对2005～2006年14个甘蔗品种云南5个试点的2年新植1年宿根甘蔗品种区域化试验蔗茎产量和蔗糖分进行基因环境互作研究分析。结果表明：①产量与环境的互作效应显著,稳定性好的品种有云瑞99-113、德蔗93-94等;甘蔗糖分与环境互作效应较小,稳定性好的品种有云瑞99-113、云蔗98-236等。②根据AMM I双标图,提出了参试品种在参试点的适应性。③根据平均产量和糖分及其Di值聚类分析,参试品种可分为5类。基于AMM I的互作稳定性分析和聚类分析为蔗区甘蔗新品种的推广应用提供了依据。
The yield and sugar of 14 varieties from 5 sites of the Yunnan regional trials in 2004-2006（2 years of planting and 1 year of ratoon crops） were analyzed using additive main effects multiplicative interaction（AMMI） model and its biplot,stability of varieties parameters（represented by Di）,mean yield and sugar and their Di values.The results of genotype and environment interaction（G×E） showed that（i） Some varieties had the significant effects and good stabilities,such as YR99-113,DZ93-94 based on the interaction between cane yield and environment;and some varieties had the little effects and good stabilities,such as YR99-113,YZ98-236,based on the interaction between sugar and environment;（ii） The adaptabilities of the varieties for trail regions were indicated by analysis of biplot of AMMI model;（iii） The varieties were hierarchically clustered into 5 types based on the mean yield and sugar and their Di value.The analysis based on AMMI and hierarchical clustering should be good contribution to new sugarcane varieties in appropriate regions.
