用中国25个省区80年代的大豆生产品种做了蛋白质、脂肪、18种氨基酸、5种脂肪酸、碘价的化学分析及其相关和通径分析.蛋白质含量,北方春大豆(A)40.86％<夏大豆(B)42.91％<秋大豆(C)43.48％<南方春大豆(D)43.91％;脂肪含量,A(19.76％)>B(18.61％)>D(18.49％)>C(17.77％);蛋白脂肪总量,D(62.56％)>B(61.45％)>C(61.25％)>A(60.64％);分析了氨基酸和脂肪酸的生态地理分布趋势;发现了高必需氨基酸(37.25),高苯丙氨酸(7.87),高含硫氨基酸(2.59),高色氨酸(1.38),低亚麻酸(4.86),低碘价(117.17)的各种优质品种;讨论了品质性状的生态地理分布和品质育种问题。
Chemical analysis of protein, fat, 18 kinds of amino acids, 5 kinds of fatty acids and iodine values and their correlation and path analysis were done with soybean production varieties from 25 provinces and autonomous regions of China in 1980. The protein content was 40.86% <42.91% for summer soybean (B), 43.48% for autumn soybean (C), 43.91% for southern spring soybean (D), 18.76% for B, 18.61% for B, 18.49% for C, %); Total amount of protein fat, D (62.56%)> B (61.45%)> C (61.25%)> A (60.64%); analyzed the ecological geographical distribution of amino acids and fatty acids; found high essential amino acids , High phenylalanine (7.87), high sulfur amino acid (2.59), high tryptophan (1.38), low linolenic acid (4.86) and low iodine value (117.17) The ecological and geographical distribution and quality breeding problems.
