Abstract:To excavate and accurately utilize Arachis hypogaea resources in Fujian, five geographical indication varieties with different phenotype and seed coat color, including 'Laifang', 'Yakouxiaoliuqiu', 'Zhukouxiaozi', 'Wenhenghongyi' and 'Yanghou', were collected. Their biological traits were described in details and the nutritional components, such as fatty acid, mineral element, vitamin E, and sterols were analyzed. The appearance characteristics and seed coat color of these peanut varieties were different. The main stem height or lateral branch length was negatively correlated with individual plant productivity. Contents of protein, fat, soluble sugar, dietary fiber, fatty acid, mineral elements and bioactive components in different peanut varieties were significantly different (P < 0.05). Among these, the contents of protein in 'Yakouxiaoliuqiu', fat, O/L value, vitamin E, and resveratrol in 'Zhukouxiaozi', Fe and phytosterol in 'Wenhenghongyi' was the highest, respectively. These results indicated that all five special peanuts accord with the grade 1 standards for direct consumption and grade 3 peanuts for oil, and have obvious local characteristics such as high iron contents.
