从品种志分析吉林省大豆八十五年来育成品种的亲本来源

Analysis on Parent Resources of Released Soybean Cultivar during Past 85 Years in Jilin Province

对吉林省1923～2007年以来育成大豆品种的亲缘关系进行了分析。结果表明：含黑龙江和辽宁省血缘品种（品系）进入吉林省最早，并且较多，20世纪50年代以前就开始应用，1923～2007年以来引入黑龙江和辽宁品种（品系）分别29个、15个；其它省份引入血缘品种较少，总计9个品种（品系）．外国品种在吉林省应用较晚，20世纪80年代才开始应用，但引入速度较快，90年代以后有19个外国品种被引人吉林做亲本，含有外国血缘品种占其育成品种38．5％。随着年代推移，含有外来血缘品种比例越来越大，表明吉林省一直在努力拓宽大豆种质资源的遗传基础。

Excellent germplasm resource is the basis to gain breakthrough in soybean breeding progress. The present study was aimed to analysis on parents of soybean released cultivars and the geographic source of ancestors and direct parents, so as to summarize the experience of selecting parents and provide reference for soybean breeding. The article analyzed the genetic relationship of soybean released cuhivars from 1923 to 2007 in Jilin Province. Cuhivars or strains containing consanguinity of Heilongjiang and Liaoning were introduced and applied in Jilin before 1950＇ s. Introduced cuhivars from Heilongjiang and Liaoning were respectively 29 and 15 from 1923 to 2007. Only 9 cultivars containing consanguinity of other province were introduced. Foreign cultivars were applied after 1980＇s and 19 cuhivars containing foreign consanguinity were released, account for 38.5% of released cultivars. The proportion of cuhivars containing foreign consanguinity showed significant increasing trend, suggests the genetic basis of soybean germplasm resource in Jilin Province has been widen greatly.
