摘要
以辽宁省2004～2005年新育成的26个中晚熟品种为试验材料，分析了辽宁省水稻新品种的品质现状，结果表明：水稻新品种在糙米率、整精米率和直链淀粉指标上基本能达到国家优质米标准，而在垩白粒率、垩白度上差距较大，只有20％左右的品种达到了一级米标准。两年多点试验表明：水稻的品质性状存在很大的生态变异性，稻米品质均显著或极显著受基因型、环境及其互作的影响，但基因型与环境效应对各性状所起的作用不同，糙米率、垩白性状和直链淀粉含量主要受基因型影响，而整精米率和垩白度主要受基因型×环境互作的影响。
Newly bred 26 of mid-late maturing varieties in Liaoning province during 2004 - 2005 were tested on their quality traits. Results showed that all of them were able to meet the national standards for good quality rice in brow rice rate, head rice rate and amylose content. However, only 20% of them reached the first grade of good quality rice in grain ratio with chalkiness and degree of chalkiness. Result from field trails of multi spots and both years showed that there were great ecotypic variations in rice quality traits, which all were noticeably affected by genotype, environment and interaction between genotype and environment. Genotype and environment had different effects on each quality trait. Genotype had a primarily influence up on brow rice rate, stalkness and amylose content, while whole head rice rate and ratio grain with chalkiness were mainly impacted by interaction between genotype and environment.
