| 摘 要： | 日本大豆品种十胜长叶是引进种质在我国大豆育种中利用最多的品种之一.对2005年以前利用十胜长叶育成的195个大豆品种进行了系谱分析,旨在明确十胜长叶对各育成品种的遗传贡献率,总结其利用方式,为国外种质的利用提供依据.通过分析发现,利用十胜长叶衍生育成的品种分布在吉林、黑龙江、辽宁、北京4个省市,它所衍生的品种数分别为96个、89个、8个和2个;平均遗传贡献率分别为13.04%、14.99%、20.31%和7.81%.其中92.2%的品种是由杂交育成的.十胜长叶对这些品种的遗传贡献率范围为0.78%～50.00%,以遗传贡献率为12.50%、6.25%和25%的衍生品种数较多,占衍生品种总数的77.3%,说明十胜长叶的利用以至少三交效果比较好,通过复交有利于聚合国内外品种的优良特性.十胜长叶在我国大豆育种中的成功利用说明,通过与当地品种杂交选育创造优良中间材料是利用国外引进种质改良我国大豆品种的有效育种途径. |

| Abstract: | Tokachi-Nagaha introduced from Japan is one of the widely utilized elite soybean germplasm in Chinese soybean breeding. In this paper, 195 soybean cultivars released before 2005 were analyzed based on their pedigree for the contribution of their common parent of Tokachi-Nagaha. The number of cultivars derived from Tokachi-Nagaha and its contribution were 96 and 13.04%in Jilin province,89 and 14.99% in Heilongjiang province,8 and 20.31% in Liaoning province,2 and 7. 81% in Beijing, respectively. The contribution ratio of Tokachi-Nagaha to various cultivars ranged from 0.78% to 50.0% ,in which there were 77.3% cultivars with the contribution ratios of 12.50%,6.25% and 25%. Among these cultivars,96%of them were developed by hybridizing method. The results suggest that Tokachi-Nagaha could be well utilized by multiple crossing in order to pyramid favorite traits among different parents. Successful utilization of Tokachi-Nagaha in soybean breeding shows that it is an important breeding approach to enhance lines as media tO corporate introduced germplasm into breeding program for broadening genetic base of modern cul- tivars. |
