在对１９２３～１９９５年育成的６５１个中国大豆品种系谱分析的基础上，计算每一育成品种祖先亲本的细胞核和细胞质遗传贡献值。在全国３４７个细胞核祖先亲本和２１４个细胞质祖先亲本中，来自东北、黄淮海、南方及国外的祖先亲本对全国育成品种细胞核与细胞质遗传贡献分别为４８．２３％和５０．５４％，２５．５０％和２９．４９％，１３．７４％和１６．２８％，１１．９５％和２．９２％。进一步分析了东北、黄淮海、南方三大生态区大豆育成品种的核、质来源，包括国外引种所占的份额及其特点。评选出３８个对全国和三大生态区域遗传贡献最大的种质
Based on the pedigree analysis of 651 Chinese soybean varieties bred from 1923 to 1995, the genetic contribution of nucleus and cytoplasm of each progeny parent was calculated. Among 347 nuclear ancestral parents and 214 cytoplasmic ancestral parents nationwide, the ancestral parents from the northeast, Huang-Huai-Hai, southern and foreign countries contributed 48.23% and 50.54% to the cytoplasmic and cytoplasmic genetic components of the bred varieties respectively. 50% and 29.49%, 13.74% and 16.28%, 11.95% and 2.92% respectively. Further analysis of the nuclear, qualitative sources of soybean breeding varieties in Northeast, Huang-Huai-Hai, southern three ecological zones, including the share of foreign introduction and its characteristics. Thirty-eight germplasms that contributed the most to the nation and the three major ecological regions were selected
