利用ＳＤＳ－ＰＡＧＥ分析了黑龙江省７０年代以前推广种植的６３个主要小麦品种的ＨＭＷ麦谷蛋白亚基。根据Ｐａｙｎｅ等人的方法，计算了其Ｇｌｕ－１品质得分。结果表明，黑龙江省５０年代以前（包括５０年代）推广种植的２２个小麦品种，其Ｇｌｕ－１的平均分数为８．０５分；６０年代推广的１５个品种，其Ｇｌｕ－１的平均数为８．０３分；７０年代推广的２６个品种，其Ｇｌｕ－１的平均分数为７．３５分。本文分析了这一结果的成因，讨论了我省小麦育种的策略和方法。
The HMW glutenin subunits of 63 major wheat varieties popularized before the 1970s in Heilongjiang Province were analyzed by SDS-PAGE. The Glu-1 quality score was calculated according to the method of Payne et al. The results showed that the average score of Glu-1 in 22 wheat varieties popularized before 1950s (including 1950s) in Heilongjiang Province was 8.05 points. The average number of Glu-1 in 15 varieties promoted in 1960s was 8.03 points; 26 varieties popularized in the 1970s, the average score of Glu-1 is 7.35 points. This paper analyzes the causes of this result and discusses the strategies and methods of wheat breeding in our province.
