Screening of Soybean Variety Resources in Northeast China
摘要
Abstract
In recent years, the increase of domestic demand for soybean, the insufficient science and technology input in soybean production, and the slow increase of per unit area yield have caused more obvious imbalance between supply and demand. New soybean variety breeding has always been the objective of plant breeders for a long time. Excellent varieties are the basis of soybean high yield. In choosing soybean varieties, local climate and farming condition should be taken into account, varieties suitable for close planting and with resistance to pests and diseases and lodging should be selected. The authors selected 50 varieties which were suitable for the second accumulated temperature zone in Heilongjiang from 572 soybean variety resources, and the genetic structure, genetic background and genetic relationship of those 50 varieties were studied, and the variety adaptability in all areas was also analyzed. The results provide a theoretical direction for the innovation and utilization of excellent germplasm resources, and provide information for new variety breeding.关键词
