高油酸花生遗传育种研究进展

Advances in Genetics and Breeding of High Oleic Acid Peanut

花生是我国重要的油料作物,子仁中油酸和亚油酸的含量达到80%左右,其中油酸是影响花生油理化稳定性和营养价值的重要品质指标。"十五"以来,为进一步提升我国花生国际竞争力和满足国内人们对高品质花生油的消费需求,培育高油酸花生品种成为我国重要的花生品质育种目标之一。本文综述了国内外高油酸花生突变体、高油酸含量性状的遗传规律和分子机理、育成发放的高油酸花生品种的研究进展,对高油酸花生品种系谱、育成方式进行分析。分析高油酸花生育种中存在的问题,以期为我国高油酸花生育种提供参考。

Cultivated peanut（Arachis hypogea L.）is an important oilseed crop in China.Oleic content and linoleic content of peanut seed add up to 80%.Oleic acid is an important factor which affects physical and chemical stability,also nutritional value of peanut oil.Breeding peanut variety with high oleic content is an important breeding objective of peanut quality to promote international competitiveness and meet domestic consumption demand since 2000.Increasing oleic content in peanut significantly improves the nutritional quality.In this paper,we summarized mutants of high oleic peanut,the genetic characteristics of high oleic acid content,analyzed pedigree relationship of high oleic acid peanut varieties and developing methods.Our purpose is to improve high oleic breeding of Chinese peanut.
