摘要
以宁夏不同年代育成的40份审定主栽品种为研究对象,根据1999版和2017版优质稻谷国标分析了4个主要品质性状整精米率、垩白度、直连淀粉含量及优质等级的变化规律,统计各个性状变异幅度、变异系数,初步探明宁夏水稻品种品质性状演替规律。
Taking 40 authorized cultivars of different ages in Ningxia as subjects,according to High Quality Paddy(GB/T 17891—1999)and High Quality Paddy(GB/T 17891—2017),variation regulation of quality traits of main cultivars including head rice rate,chalkiness,amylase content and high quality level were analyzed,and variation range and coefficient of variation were calculated in order to explore succession regulations of varieties and quality traits of rice in Ningxia.
