１９８９年以前对国内外２万份小麦遗传资源进行了蛋白质含量测定并筛选出一批高蛋白品种。１９９０年以后对已筛选出的高蛋白品种每年在不同生态地区进行多点繁种，连续７年做了高蛋白品种的重复筛选，最终筛选出蛋白质平均含量超过（或等于）公认的高蛋白对照品种阿特拉斯６６的１２份品种。这些品种的高蛋白特征总体上已排除了环境因素的作用，是由其遗传基因形成的，这一情况通过杂交进行基因转移得到进一步证实。 Prior to 1989, the protein content of 20,000 wheat genetic resources at home and abroad were determined and a number of high protein varieties were screened. After 1990, the screened high-protein varieties are cultivated in different ecological regions for many times every year, and the high-protein varieties are repeatedly screened for seven consecutive years. Finally, the average protein content exceeds (or is equal to) the recognized high-protein control Atlas 66 varieties of 12 varieties. The high-protein traits of these breeds have generally ruled out the role of environmental factors in their genetic makeup and are further confirmed by genetic transfer through hybridization.
