Abstract:

The appearance and nutritional quality of peanut kernel are important factors for evaluation of peanut for food-use. Our The present study assessed and analyzed these quality traits of 258 peanut germplasm accessions. The aim of the study is to provide guidance for breeding of peanut as food source. Thirteen 13 agronomic traits including five nutritional quality traits and eight appearance factors were examined for 258 accessions. The results showed that these accessions can be divided into two large groups and six sub-groups. Interestingly, the clustered accessions were highly correlated withBased on botanical classification, plant type and origin. Diverse variations in kernel morphological traits were observed in these germplasm and could meet specific needs for different processing application. However, Germplasms with either high oleic acid content or high protein content and low oil content are less. The strategy for selecting parents for food-use peanut cultivars breeding was discussed and the potential type of parents was proposed. Based on the industrial purpose of roasted and confectionary peanut, germplasm of irregular type, hypogaea type, and vulgaris type with middle to large sized peanut with kernal high oleic acid , high protein , and low fat content could be chosen as crossing parents. Traits of high oleic acid content, high protein content, and low fat content should be focus on for further improvement.
