测定814份吉林省大豆品种资源蛋白质及18种氨基酸含量。我省大豆种质蛋白质含量较低,平均41.83%。地方品种地区分布趋势,东部地区高,西部地区低。氨基酸含量以谷氨酸最高,其次为天门冬氨酸,平均含量分别为18.66%、11.33%。限制性氨基酸蛋氨酸和胱氨酸含量相对高于黑龙江省和辽宁省品种,平均含量分别为1.32%、1.51%。不同熟期类型品种蛋白质及含硫氨基酸分析比较结果,蛋白质含量:晚熟类型品种>早熟类型品种;含硫氨基酸则相反,早熟类型品种>晚熟类型品种。不同栽培类型品种蛋白质及含硫氨基酸含量分析比较结果,蛋白质含量;半栽培大豆>栽培大豆,地方品种>育成品种;含硫氨基酸含量:半栽培大豆>栽培大豆,育成品种>地方品种。半栽培大豆蛋白质含量高,含硫氨基酸含量亦较高,在种质资源利用上,值得重视。鉴定筛选出蛋白质含量47%以上的种质17份,蛋氨酸含量高于1.6%的种质7份,胱氨酸含量高1.75%的种质10份,列出保存编号,品种名称,来源与产地,供育种选用。
The content of protein and 18 kinds of amino acids in 814 soybean cultivars in Jilin Province were determined. Soybean germplasm in our province lower protein content, an average of 41.83%. The distribution trend of local varieties is high in the eastern region and low in the western region. The content of amino acid was glutamic acid highest, followed by aspartic acid, the average content were 18.66% and 11.33% respectively. Restricted amino acids methionine and cystine content is relatively higher than the varieties of Heilongjiang Province and Liaoning Province, the average content was 1.32%, 1.51%. Comparison of protein and sulfur-containing amino acids in different maturity cultivars, protein content: late-maturing varieties> early-maturing varieties; sulfur-containing amino acids in contrast, early maturing varieties> late maturing varieties. Analysis of Protein Content and Sulfur Amino Acid Contents in Different Cultivar Cultivars, Protein Content; Semi-cultivated Soybean> Soybean Cultivars, Local Varieties> Bred Varieties; Sulfur-Containing Amino Acids Content: Semi-cultivated Soybean> Cultivated Soybean, Cultivars> Local Varieties. Semi-cultivated soybean protein content, sulfur amino acid content is also high, the utilization of germplasm resources, it is worth attention. Seventeen germplasm with more than 47% protein content, seven germplasm with methionine content greater than 1.6% and ten germplasm with high content of cystine were screened and identified. The number, variety name, origin and origin , For breeding selection.
