Analysis of the Parentage Compositions Among Soybean Cultivers(lines) Developed in Jilin Province

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.
