摘要
通过对1989～1994年参加吉林省大豆品种区（预）域试验的274份大豆新品种（系）的血缘组成分析，揭示了目前吉林省大豆育种的现状，即育成品种（系）遗传基础狭窄、外来种质渗入较少、育种模式十分单一、育种队伍过于庞大等，提出应及时调整现行状况，重新规划育种程序及布局。
Analysis of the parentage compeitions about 274 soybean cultivers(lines) developed from. the soybean varieties regional test and preliminary test in Jilin Province from 1989 to 1994, showed that the genetic base of ones was relatively narrow, the parent germplasms introduced were very few, the breeding method was extremely unitary but the breeding orgnization was more than unwieldy. Therefore it is necessary to readjust promptly the current situation of soybean breeding in Jilin Province and to plan a new soybean breeding procedure and distribution.
