Parental Pedigree Analysis of'Hedou'Series Soybean Varieties
摘要
Abstract
A comprehensive analysis of the parental lineage composition of the'Hedou'series of soybean varieties was conducted to provide scientific guidance for parental selection in soybean breeding research.Using 20'Hedou'series soybean varieties as materials,lineage diagrams and genetic contribution value statistics were employed to explore their parental types,hybridization patterns,and the genetic contributions of nuclear and cytoplasmic ancestor parents.The results indicated that all'Hedou'series soybean varieties were developed through hybridization,primarily utilizing two combination modes:'cultivated variety×cultivated variety'and'cultivated variety×high-generation line'.The direct parents of the'Hedou'series included 22 varieties,primarily sourced from Shandong,Henan and Beijing.The nuclear ancestor parents of the'Hedou'series soybean varieties numbered 42,with an average of 2.1 nuclear genetic ancestor parents per variety,and the highest nuclear genetic contribution came from'Binhaidabaihua'.There were 4 cytoplasmic ancestral parents of'Hedou'series soybean varieties,with'Binhaidabaihua'having the highest genetic contribution rate.The backbone parents of the'Hedou'series soybean varieties primarily included'Zhonghuang 13','He 84-5','Hedou No.12',and'Hedou No.20',with'Zhonghuang 13'serving as the direct parent for 5 derived varieties.The'Hedou'series soybean varieties exhibited a rich nuclear genetic basis but a narrower cytoplasmic genetic basis.Future breeding efforts should optimize parental selection and enhance germplasm innovation.'Zhonghuang 13'and'Hedou No.12'are important backbone parents for soybean variety selection and should be prioritized for use.This study provides important theoretical support and practical guidance for soybean breeding.关键词
