摘要： 利用不同环境条件下的试验资料分析了遗传主效应和环境互作效应对籼稻5个外观品质性状的影响。结果表明，糙米长、糙米长宽比和糙米长厚比主要受制于遗传主效应，而糙米宽和糙米厚的表现则主要受到环境互作效应的影响。其中糙米长、糙米长宽比和糙米长厚比3个性状的遗传主效应以母体效应为主，而糙米宽和糙米厚的遗传主效应则以细胞质效应为主。在环境互作效应中，所有外观品质性状均以母体互作效应为主。基因的加性效应和加性互作效应是影响糙米长、糙米长宽比和糙米长厚比表现的主要因子，而糙米宽和糙米厚则主要受制于基因的显性效应。遗传效应预测值结果表明，浙协2号A、协青早A、V20A、测早2-2等是改良杂交后代稻米外观品质性状的良好亲本，其中浙协2号A亲本的外观品质性状预测值在两年中的环境互作效应较为一致，不易受到外界条件的影响。

Abstract: Genetic and genotype Xenvironment interaction effects were studied for apparent quality traits, including brownrice length(BRL), brown rice width (BRW), brown rice thickness (BRT), ratio of length to width of brown rice (RLW) and ra-tio of length to thickness of brown rice (RLT), of indica rice in different environments. Results indicated that BRL, RLW andRLT were mainly controlled by genetic effects, and BRW and BRT were mainly in f1uenced by genotyPe X environment interac-tion effects. Among the genetic effects, maternal effects were the principal components for BRL, RLW, and RLT, whiIe cyto-plasmic effects were the principal components for BRW and BRT. Among the genotype Xenvironment interaction effects, all ap-parent quality traits were mainly affected by maternal Xenvironment interaction effects. Additive effects and additive by envi-ronment interaction effects prirnarily controlled the performance of rice apparent quality traits, except for BRW and BRT whichwere affected by dorninance effects. The predicted genetic effects indicated that the genetic effects of Zhexie 2A, Xieqingzao A,V2o A, and Cezao 2-2 were better parents for improving rice apparent quaIity traits of progenies. The predicted genotype Xenvi-ronment interaction effects showed that the genetic stabiIity of Zhexie 2A in different environments were expected.
