Background

The nutritional quality, flavor, and shelf-life of both peanut products and its seeds are dependent on relative quantity of various fatty acids (FAs) like saturated, mono unsaturated fatty acid (MUFA) and poly unsaturated fatty acid (PUFA) present in its oil. High oleic (HO) peanut oils are extremely valued due to its superior nutritional composition for human health and augmented thermo-oxidative stability for industrial purposes.

Scope and approach

From the research perspective, noteworthy progress has been made during last three decades for the development of peanut lines having HO trait in its oil. In this review, the research achievements, perspectives, and prospects of peanut genetic improvement for HO trait is thoroughly discussed.

Key findings and conclusions

The research has helped not only understanding the genetics of HO traits and its genotype (G) by environment (E) interaction but also produced an enormous number of HO line throughout the world. Although, as of now, most of the high O/L cultivars developed are the outcome of traditional breeding efforts. But, with the advent of novel molecular techniques like CAPS and AS-PCR assay for HO peanut breeding program, it is extremely easy to achieve the traits through marker assisted selection (MAS) rather than through either conventional or genetic engineering approaches. The availability of peanut genome sequence and identification of different ahFAD2 gene families is also expediting the research for the breeding of HO peanut genotypes.

高油酸花生育种：成就，前景和前景

背景

花生产品及其种子的营养质量，风味和保质期取决于其中存在的各种脂肪酸（如饱和，单不饱和脂肪酸（MUFA）和多不饱和脂肪酸（PUFA））的相对含量。油。高油酸（HO）花生油因其对人体健康的卓越营养成分和增强的工业用途热氧化稳定性而备受推崇。

范围和方法

从研究的角度看，在过去的三十年中，其油中具有HO特性的花生品系的开发取得了显着进展。本文综述了花生遗传改良HO性状的研究成果，前景和展望。

主要发现和结论

该研究不仅通过环境（E）相互作用帮助了解了HO性状的遗传学及其基因型（G），而且在世界范围内产生了大量HO系。尽管到目前为止，开发的大多数高O / L品种是传统育种努力的结果。但是，随着CAPS和AS-PCR测定等新型分子技术用于HO花生育种计划的出现，通过标记辅助选择（MAS）而不是通过常规或基因工程方法来实现性状极为容易。花生基因组序列的可获得性和不同ahFAD2基因家族的鉴定也促进了HO花生基因型育种的研究。
