摘要
对吉林省1987～2002年审(认)定的大豆品种进行系谱分析结果表明,全省育成的高产、高脂肪、高蛋白和小粒类型(百粒重10g左右)等108个大豆品种,以杂交育种途径育成96个品种,占育成品种总数的88.9%。其中51个品种是由吉林20号等14个亲本参与的组合中选育而成。13个高脂肪大豆品种的平均脂肪含量为22.43%;15个高蛋白大豆品种的平均蛋白质含量在45.65%,蛋白质含量呈超亲遗传;13个大豆品种的蛋白脂与脂肪总含量平均64.26%,既育成品种中的双高品种。育成品种的主要遗传成份由少数亲本占主导地位,组合亲本资源少,品种之间的亲缘关系相近。分析育成品种的部分性状,并进行了讨论。
The spectrum analysis result of soybean varieties which were identified by jilin from 1987 to 2002 indicated that among 108 high yield, high protein, high oil and small grain type ( about 10 gram per hundred grains ) bred by cross is 96, occupied 88.9%. Among the 96 varieties 51 varieties were bred by combined Jilin 20 and other parents, 13 high oil varieties contain 22.43% oil on the average, 15 high protein varieties contain 45.65% protein on the average which showed surpass parents heredity, 13 varieties contain protein and oil 64.26% which named double high varieties. The main heredity composition come from few parents, component parents source is lack, the relationship of varieties is close. This paper also discusses some character of bred cultivars.
