一、前言蛋白质是人体生长和发育的必需营养成分。小麦是人类植物蛋白的主要来源之一。在主要粮食作物中,小麦蛋白质含量是比较高的,目前世界小麦的平均蛋白质含量大约为13%。美国内布拉斯加大学对1.2万多个普遍小麦和硬粒小麦品种(系)的分析表明,蛋白质含量的变异幅度在6.9～22.0%之间;中国农林科学院1976年对全国小麦良种231个样品分析中(冬性品种89个,春性品种142个),籽粒蛋白质 First, the introduction of protein is the body’s growth and development of essential nutrients. Wheat is one of the main sources of human plant protein. The wheat protein content is relatively high in the main food crops, and the world average wheat protein content is currently about 13%. Analysis of over 12,000 varieties of universal wheat and durum wheat at the University of Nebraska showed that the variation of protein content ranged from 6.9% to 22.0%. The Chinese Academy of Agriculture and Forestry in 1976 evaluated 231 wheat varieties In the sample analysis (winter, 89, spring, 142), grain protein
