根据吉林省2003年中早、中熟4个品种区域试验点38个参试品种12项品质性状的测定结果,研究了各品质性状的品种(基因型)、地点、品种×地点互作效应相对变异。结果表明,垩白性状、直链淀粉含量、精米率、粒长的国家一级达标率极低;各品质性状在品种间、环境(地点)间都有极显著差异,而且各品质性状均存在品种×地点交互作用;参试品种均以品种效应为主,品种效应最大的是直链淀粉含量,环境效应最大的是整精米率。
According to the determination results of 12 quality traits of 38 tested varieties in the middle-early maturity and medium maturing regions in 2003 in Jilin Province, the effects of variety (genotype), location, variety × location on each quality trait were studied variation. The results showed that the attainable rates of chalky traits, amylose content, milled rice rate and grain length were extremely low at the national level. The quality traits showed extremely significant differences among cultivars and environments (loci), and all the quality traits existed Variety × site interaction; Varieties are the main variety of varieties tested, the largest variety is the amylose content, the largest environmental effects of milled rice rate.
