摘　　要：对黄淮海地区自1980年以来国外种质的衍生品种进行系统的分析,明确了其对黄淮海地区衍生品种的遗传贡献。分析发现黄淮海地区育成的550个品种共使用了42个国外种质,遗传贡献排在前5位的依次是Mamotan、William、Clark63、Magnolia和Williams82。在黄淮海地区7个省份和地区中,北京地区和江苏省大豆育成品种中具有国外种质血缘的品种占有比例较高,分别使用了23个和9个国外种质;山东省和山西省育成品种中具有国外种质血缘的品种比例较低,分别使用了16个和12个国外种质。分析还发现,后期育成品种中具有国外种质血缘的比例高于前期育成品种,黄淮海各个地区利用的国外种质有所不同。The genetic contribution of foreign germplasm to soybean cultivars in Yellow-Huai-Hai Rivers Valley was analyzed, the result showed that 42 foreign varieties were used in soybean breeding in the region from 1980 to 2016. The gerplasms that inheritance effect value was in top five were Mamotan, William, Clark63, Magnolia and Williams82. In Yellow-Huai-Hai Rivers Valley, the cultivar proportion that derived from foreign germplasm in Beijing and Jiangsu province were higher than other provinces, 23 and 9 foreign germplasm were used in these regions, but that in Shandong province and Shanxi province were lower than other regions, 16 and 12 foreign germplasm were used in these regions. The results also showed that the cultivar proportion that derived from foreign germplasm released lately was higher than that released early, and the utilized foreign varieties in different province in Yellow-Huai-Hai Rivers Valley was significant differently.
