黑龙江省大豆品种脂肪和蛋白质含量变化的初步研究

为了给今后大豆品质育种提供依据,分析了黑龙江省大豆品种脂肪和蛋白质含量变化。结果表明:322个大豆品种的平均蛋白质含量为40.12%,355个大豆品种的平均脂肪含量为20.61%。蛋白质含量最高的品种为1983年推广的东农36,其蛋白质含量为46.02%;脂肪含量最高的品种为1941年推广的满仓金,其脂肪含量为23.87%。蛋白质含量以20世纪80年代最高,平均为40.76%;脂肪含量以20世纪60年代最高,平均为21.76%。322个大豆品种的蛋白质含量和脂肪含量之和平均为60.71%,以20世纪80年代的蛋脂之和最高,为61.18%。蛋白质含量和脂肪含量的相关系数为-0.619 5;脂肪含量、蛋白质含量与产量、百粒重、生育日数没有显著的相关性。高脂肪含量和高蛋白含量也与产量、百粒重、生育日数没有显著的相关性。

Preliminary Study on Change of Oil and Protein Content of Soybean Varieties in Heilongjiang Province

In order to provide a basis for future soybean breeding in quality,the oil and protein content changes of soybean varieties in Heilongjiang province were analyzed.The results showed that the average protein content of 322 soybean varieties was 40.12%,the average oil content of 355 soybean varieties was 20.61%.The highest protein content of varieties was Dongnong 36 bred in 1983,which protein content was 46.02%;the highest oil content of varieties was Mancangjin bred in 1941,which oil content was 23.87%.In view of times,the highest protein content of varieties was in 1980s,the average was 40.76%;the highest oil content of varieties was in 1960s,the average was 21.76%.The average of sum of protein and oil content of 322 varieties soybean was 60.71%,the highest in 1980s was 61.18%.The correlation coefficient of protein and oil content was-0.619 5;oil content,protein content and yield,100-grain weight,number of growing days were no notable correlation.High oil content and high protein content had no notable correlation with the yield,100-grain weight and number of growing days.
