为了研究三江平原大豆主栽品种蛋白质与脂肪含量及蛋脂总和的变化规律,选用不同年代18个同熟期的主栽品种为试验材料,采用田间小区试验方法,系统地研究主栽品种更替过程中品质性状的改进与变化规律。结果表明:随着年代的推进,脂肪含量无明显规律性变化,总体呈波动式降低趋势,变化幅度为19.88%~21.41%,平均脂肪含量为20.68%。阶段性变化:20世纪50年代到60年代呈增加趋势,60年代到80年代呈降低趋势,80年代到2000年后呈升高趋势;蛋白质含量也无明显规律性变化,总体呈升高趋势,变化幅度为37.22%~40.94%,平均蛋白质含量为39.34%。阶段性变化:20世纪50年代到80年代呈增加趋势,80年代到2000年后呈下降趋势;蛋脂总和无明显变化规律,总体呈波动式增加的趋势,幅度为58.34~60.81%,平均蛋脂总和为60.02%。
In order to study the variation of protein and fat content and total egg yolk in main cultivars of soybean in Sanjiang Plain, 18 main cultivars with the same maturity in different years were selected as test materials, field trials were conducted to systematically study the alternation of main cultivars The improvement and change of the quality traits. The results showed that with the promotion of the age, there was no obvious regularity of the fat content, and the overall trend was fluctuant decreasing with the range of 19.88% -21.41% and the average fat content of 20.68%. The changes of the stages were from 1950s to 1960s, from 1960s to 1980s, from 1980s to 2000s, and from the 1980s to the 2000s. The protein content also showed no obvious regularity, The change range is 37.22% ~ 40.94%, the average protein content is 39.34%. Stages of change: from the 1950s to the 1980s showed an increasing trend from 80 years to 2000 years after the decline trend; no significant changes in the total amount of egg fat, the overall trend of increasing volatility, the range of 58.34 ~ 60.81%, the average egg The total fat is 60.02%.
