| 摘 要： | 以2004年和2005年参加辽宁省水稻区试的26个中晚熟品种为试材,对品种的产量特性及基因×环境互作进行研究。结果表明：年份×地点互作效应和地点效应是影响产量和产量性状的主要随机因素。有效穗和穗粒数在地点间的变异最大,结实率在品种间的差异最大。

| Abstract: | 26 mid-late season varieties newly bred in Liaoning during 2004～2005 was tested on their yield trait.Result show that： There were great ecotypic variability exist in rice yield traits,which all were affected by genotype,environment and their interaction.Genotype and environment had different effects on each quality trait.G×E and environment mostly affecte yield,while Panicles and Spikelets was mainly affected by environment.Percentage of ripened grains was was mainly affected by genotype. |
