The mean protein content of seeds and amino acid composition of seed protein in cultivated, semi-cultivated and wild soybeans were determined in 1982. 50 cultivars of cultivated soybean, 21 lines of semi-cultivated soybean, 41 lines of wild soybean and 17 lines of progenies of natural crossing were used in this research.The mean of protein content of cultivated, semi-cultivated and wild soybeans were 39.12%, 39.97% and 41.04% respectively. The difference of protein content between wild and cultivated soybeans...

The mean protein content of seeds and amino acid composition of seed protein in cultivated, semi-cultivated and wild soybeans were determined in 1982. 50 cultivars of cultivated soybean, 21 lines of semi-cultivated soybean, 41 lines of wild soybean and 17 lines of progenies of natural crossing were used in this research.The mean of protein content of cultivated, semi-cultivated and wild soybeans were 39.12%, 39.97% and 41.04% respectively. The difference of protein content between wild and cultivated soybeans was statistically significant at the 10% level.Similarity in the pattern of amino acid composition was found among cultivated, semi-cultivated and wild soybeans. As shown in table 2, no significant differences were found in the content of amino acid among types of soybeans except aspartic acid, phenylalanine, histidine and arginine. Methionine and cystine contents showed relatively wide range of value and high coefficien of variation.With regard to the correlation between protein content and amino acid in all types of soybeans, there were negative correlation between most amino acid composition and protein content, especially there were highly significant negative correlation between sulfer-containing amino acid (methionine and cystine) content and protein content in all types of soybeans.

本文分析了栽培、野生、半野生大豆及天然杂交种种子蛋白质含量及其氮基酸组成。 种子蛋白质含量平均以野生大豆最高,栽培大豆最低,半野生大豆和天然杂种的蛋白质含量相似,介于栽培和野生大豆之间。 大豆种子蛋白质的氨基酸组成比较齐全,硫氨基酸(胱氨酸、蛋氨酸)含量较低。大豆类型间含硫氨基酸含量差异不明显。栽培大豆的天冬氨酸和苯丙氨酸含量显著高于野生大豆,而组氨酸和精氨酸含量显著低于野生大豆。 大豆种子蛋白质含量与含硫氨基酸含量呈显著的负相关。因而在提高蛋白质含量的同时提高含硫氨基酸含量是困难的。但大豆品种(品系)间含硫氨基酸含量差异较大,筛选含硫氨基酸含量高的资源是有可能的。 高纬度地区栽培大豆蛋白质含量低于低纬度的大豆。野生大豆则相反,高纬度地区野生大豆蛋白质含量高于低纬度地区野生大豆。

Identification of resistance to soybean borer in soybean germp-lassm was continualy curried out during 1982-1984. About 3109 culti-vars and lines with resistance to soybean borer were screened in the three years. 18 of the 3109 cultivars and lines were resistant. 6 of the 18 resistant cultivars or lines, ERI 1001、1002、1003、1004、1006、1009 had indermediate growth season in Gongzhuling. They may be used for soybean resistance breeding,

大豆品种资源抗大豆食心虫鉴定,1982—1984年三年来共鉴定3109份,肯定其中1300份抗感性。筛选出高抗材料18份,其中中熟高抗的6份为ERI1001、ERI1002、ERI1003、ERI1004、BRI1006、ERI1009,可作为抗食心虫育种的亲本材料。此外,总结提高鉴定技术方法,探讨品种的兼抗性,多抗性,初步了解国育98—4等裸大豆类型兼抗食心虫大豆蚜;ERSGD_(12),ERSGD_(14)等兼抗食心虫及病毒病。

Wild soybean(Glycine soja)germplasms were used for increasing genetic base of soybeans in breeding,progenies of interspecies hybrids between G.max ×G.soja and G.gracilis are usual to trail and lodge,and could unsnrelyisolate to produce forms of G.max.In recent years,many crosses were made between G.max×G.soja and G.gracilis.If parents were selected correctlly and were used to make crosses of interspecies,some progenies with characters of cultivated soybean could be isolated from interspecies crosses,crosses of early G.max×late G.soja and G.gracilis,G.max of determinate and semideterminate growth habit×G.soja(all of G.soja are indeterminate),dwarf G.max×G.soja and G.gracilis could isolate to produce forms of cultivated soybean.G.soja and G.gracilis were crossed with a G.max to determine the parental combining ability,and to find superior wild or,semi-wild parents.In backcrossing,cultivated forms should be selected from F2 generation and used as parents to make backcrosses.When cultivars with large seeds were used to make interspecies crosses,the the progenies of such crosses often isolate to produce cultivated forms.

野生大豆作亲本,其杂种后代往往蔓化倒伏.早熟栽培大豆和晚熟野生或丰野生大豆杂交,有限、亚有限结荚习性或矮秆的栽培大豆与野生、半野生大豆杂交,F_2代较易分离出栽培大豆类型.用某一栽培大豆为测配亲本,与多个野生、半野生大豆杂交,测定亲本配合力,发现优良的野生、半野生大豆亲本.杂种后代回交,不管从那一代开始,都应选择直立或半直立栽培大豆类型的后代作亲本,轮回亲本最好是有限结荚习性的栽培大豆品种.百粒重的提高在于选择百粒重大、遗传性强的栽培大豆品种(系)作亲本.
