Abstract:

With increased content of oleic acid, palmitic acid content reduced significantly, which would be beneficial to human health. High oleic acid can significantly prolong the shelf life of peanut products. In this study, to develop edible peanut varieties with high oleic acid, cross was made using elite peanut cultivar Huayu 23 as the female parent and high oleate peanut DF12 as the male parent. F1 and the selfed offspring were examined using marker-assisted selection method. Their agronomic traits, pod appearance and kernel nutritional quality of new germplasm with high oleic acid were analyzed. We obtained a new high oleic acid peanut with 49.95% oil content, 81.3% oleic acid, 26.1% protein and 6.01% total soluble sugar. These nutritional qualities and pod appearance of this line met the requirements of edible peanut and this study provided materials for high oleate edible peanuts breeding in the future.

Key words: edible peanut, high oleic acid, marker-assisted selection, germplasm innovation Norden
