摘　　要：花生脂肪酸成分中80%以上为油酸和亚油酸,二者均属有益脂肪酸,高油酸含量是花生遗传育种的主要目标之一,借助分子辅助育种技术可提高高油酸花品种的育种效率。为高油酸花生品种选育提供技术支撑,从高油酸花生不饱和脂肪酸的生物合成途径、高油酸性状的遗传机制、分子标记辅助育种技术等方面进行概述,提出分子标记辅助选择技术与回交育种系统结合的高油酸化遗传改良策略。More than 80%of peanut fatty acids are oleic acid and linoleic acid,both of which are beneficial fatty acids.High oleic acid content is one of the main objectives of peanut genetic breeding.The breeding efficiency of peanut with high oleic acid content can be improved by molecular assisted breeding technique.The authors summarize the biosynthesis pathway of unsaturated fatty acids in peanut abundant in oleic acid,the genetic mechanism of high oleic acid characters and molecular marker assisted breeding technology,and put forward the genetic improvement strategy of high oil acidification by combining molecular marker assisted selection technology with backcross breeding system to provide technical support for the breeding of peanut varieties with high oleic acid content.
