摘要
对吉林省2018~2022年参加省品种区域试验的244个新育成的中晚熟水稻品种(品系)的品质性状进行了分析。结果表明,出糙率、整精米率、直链淀粉含量、碱消值、胶稠度、透明度等指标全部或绝大部分品种(品系)都能达到农业农村部食用稻优质3等米以上标准,而垩白度仅40.8%品种(品系)达标。说明垩白度是影响吉林省中晚熟稻米品质的主要因素。同时分析了各品质性状之间的相关性,为吉林省中晚熟优质水稻品种选育提供参考依据。
The quality traits of 244 newly grown middle and late rice varieties(lines)participating in the provincial variety regional experiment from 2018 to 2022 in Jilin Province were analyzed.The results showed that in terms of quality traits,the percentage of varieties(lines)reaching the standard of Grade 3 or above for edible rice with high quality of the Ministry of Agriculture and Rural Affairs in terms of bran removal rate,whole and milled rice rate,amylose content,alkaline dissolution value,paste viscosity,and transparency was almost 100%,while only 40.8%of them met the standard for chalkiness.This indicates that chalkiness is the main factor affecting the grain quality of mid-late rice in Jilin Province,followed by paste viscosity.At the same time,the correlation between grain quality traits was analyzed,with a view to provide a reference for the selection of high-quality mid-late rice varieties in Jilin Province.
