摘　　要：对233份河南省地方花生资源进行了蛋白质含量、含油量、油酸和亚油酸含量的全面测定,并与省外和国外资源的相关性状进行了比较分析。在河南地方品种资源中,蛋白质含量中等,平均含油量和油酸含量相对较高,但缺乏蛋白质含量超过30%或含油量超过56%、油酸含量超过70%的突出材料。河南省目前高油品种选育有明显进展,育成了一批高油花生品种,但育成品种蛋白质含量普遍偏低。提出了充分利用现有地方品种资源,积极采用远缘杂交、诱变、分子标记辅助选择技术及现代基因工程技术创制优良种质,选育优质专用品种的育种策略。The quality traits,including protein content,oil content,oleic acid,and linoleic acid content,were detected on seeds of 233 local peanut germplasms from Henan Province,China.They were compared with the traits of the germplasms from other provinces of China and countries.The landraces from Henan Province possessed medium protein contents together with relatively high oil content and oleic acid content on average.However,outstanding germplasms with the protein content over 30%,oil content over 56%,and oleic acid content over 70% were not detected.The currently commercial varieties in Henan Province had low protein content in general.However,the varieties with high oil content were developed.A breeding strategy was proposed,which included full use of germplasms available together with application of techniques such as wide hybridization,inducing mutants,marker-assisted selection,and genetic engineering.
