1973-2017年山西省审定大豆品种的系谱分析

Pedigree analysis of soybean varieties released in Shanxi Province from 1973 to 2017

为给大豆亲本选配和育种提供有益借鉴,本文对1973-2017年山西省审定的84份大豆品种进行了系谱分析,归纳出山西省大豆品种的祖先亲本和骨干亲本。山西省审定的84份大豆品种,主要来源于晋豆1号、晋豆19和徐豆1号三大家族。84份大豆品种基因库源于110个祖先亲本,细胞核祖先亲本有110个,细胞质祖先亲本有39个。核遗传贡献率最大的祖先亲本有大白麻,其次是滨海大白花、铜山天鹅蛋、Mamatan等16个种质。细胞质遗传贡献率最大的是大白麻,其次是丹66-12、京谷玉。山西省育成的84个大豆品种中,形成系谱的品种占育成品种总数的80.95%。晋豆1号作为亲本育成36个大豆品种,占育成品种总数的42.9%,为山西省大豆育种做出了重大贡献。

In order to provide useful reference for the selection and breeding of soybean parents,pedigrees of 84 released soybean varieties in Shanxi Province from 1973 to 2017 were analyzed and the ancestors and backbone parents of soybean varieties were summarized.The results revealed that: these 84 soybean varieties mainly originated from 3 major families,namely Jindou 1,Jindou 19 and Xudou 1.The gene pool of 84 soybean varieties originated from 110 ancestral parents,110 nuclear ancestors,and 39 cytoplasmic ancestors.The ancestors with a high rate of nuclear genetic contribution include 16 germplasm such as Dabaima,Binhaidabaihua,Tongshantianedan,and Mamatan.The largest cytoplasmic genetic contribution rate is Dabaima,followed by Dan 66-12 and Jingguyu.Among the 84 soybean varieties in Shanxi Province,the genealogical varieties accounted for 80.95 % of the total.Jindou 1 was bred into 36 soybean varieties as a parent,accounting for 42.9 % of the total number of cultivars,and made great contributions to soybean breeding in Shanxi Province.
