Abstract:
In the last decades，introduced soybean germplasm was used in soybean breeding，in order to broaden the genetic bases of Chinese soybean cultivars.The objective of this paper is to provide theoretical basis for the selection and breeding of distant hybrid soybean progenies.45 cross combinations of soybean，whose parents were from 4 current varieties released in Liaoning，China and 4 released in Ohio，USA，and 4 old varieties released in Liaoning in about 1920s’respectively，were arranged in incomplete diallel crosses.The agronomic parameters in F2?generation were analyzed.The results showed that the main characters of different combinations had higher genetic variation coefficients(GCV) and had a similar trend.The number of branch had the highest GCV.And the GCV of yield per plant，pod number per plant and seed number per plant also had high GCV.The 100-seed weight and plant height of different combinations had high heritability.The relative genetic schedule (RGS) of the number of branch was the biggest one，while seeds number per plant，pods number per plant，yield per plant and seed-stem rate had medium RGS.There were abundant genetic variations and great selection potential in the hybrid soybean progenies，especially the crosses with parents released in different decades.
