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 results of pedigree analysis of the soybean varieties determined in 1987 ~ 2002 in Jilin Province showed that 108 soybean varieties with high yield, high fat, high protein and small grain type (100g per 100g weight) Breeding ways bred 96 varieties, accounting for 88.9% of the total number of cultivated varieties. Among them, 51 varieties were selected from a combination of 14 parents including Jilin 20. The average fat content of 13 high-fat soybean cultivars was 22.43%. The average protein content of 15 high-protein soybean cultivars was 45.65% and the protein content was super-progeny. The total protein and total fat contents of 13 soybean cultivars were 64.26% Both breeding varieties in the double high varieties. The main genetic components of the cultivated varieties are dominated by a few parents, with less parental resources and similar genetic relationships among cultivars. Some traits of cultivated varieties were analyzed and discussed.
