摘要: 摘要:基于龙岩市1997-2002年连续6年在新罗、长汀、连城、上杭、武平和漳平6个不同生态条件的杂交早稻联合区域试验数据资料,应用AMMI模型和相应统计分析方法,分析了产量、生育期、有效穗、株高、穗长、每穗粒数、每穗实粒数、结实率、千粒重等9个产量相关性状的基因型与环境变异。结果表明,环境和基因型与环境互作(G×E)效应对考察的9个性状影响较大。其中,株高以基因型效应为主,产量、穗长、穗总粒数和穗实粒数以环境效应为主,生育期、有效穗、结实率和千粒重以基因型与环境间互作效应为主。穗实粒数、穗总粒数和产量的稳定性在多数年份都是最低的,受栽培环境及G×E互作效应影响较大;千粒重、穗长、生育期和有效穗则相对稳定,受栽培环境及G×E互作效应影响较小。今后选育、引种和利用适合龙岩市杂交早稻品种时,需考虑性状的基因型、环境、基因型与环境间互作效应,才可提高效率。

Abstract: Abstract: Based on the data collected from the early rice joint regional trials from 1997 to 2002 in Longyan’s six different ecological conditions,such as Xinluo,Changting,Liancheng,Shanghang, Wuping and Zhangping,the genotype and the environment variation of yield,growth period,effective ear,plant high,spikete length,total grains per spikete,filled grains per spikete, rate of seed setting,1000-grain weight were analyzed by AMMI model and the corresponding statistical analysis method. The results indicated that the environment and genotype-environment interaction (G×E) effect has a large effect on the nine main traits.Among them, plant high was mainly controlled by genotype, yield, spikete length,total grains per spikete and filled grains per spikete were mainly controlled by environment, growth period,effective ear, rate of seed setting,1000-grain weight were mainly controlled by genotype-environment interaction (G×E) effect.In most years,all the stability of filled grains per spikete, total grains per spikete ,yield were the lowest,and cultivation environment and G×E interaction effect had a great effect ;1000-grain weight, spikete length, growth period,effective ear had relative stability and cultivation environment and G×E interaction effect had a little effect.In the future,breeding,introduction and using early hybrid rice varieties which were suitable for Longyan city must consider the traits of genotype,environment and genotype-environment interaction effect for increasing efficiency.
