Abstract:
Twenty-three walnut varieties cultivated in Taihang Mountains area were used to study the fruit characters and kernel nutrient components of walnut in different distribution areas of Taihang Mountain area by using coefficient of variation (CV)，single trait ordering and principal component analysis，in order to screen out local walnut individual plants with excellent individual and comprehensive characters and provide high-quality germplasm resources for popularizing high-quality walnut variety and standard cultivation in Taihang Mountain area，at the same time，the breeding and genetic improvement resources of superior walnut varieties were enriched.The results showed that the coefficient of variation ranged from 3.07% to 46.65%，and the coefficient of variation of mineral element content and fatty acid content was higher according to different indexes.The No.1，No.53,No.35 and No.29 were all ranked in the top 7 of single fruit traits，and the No.1 and No.33 were the most abundant in protein and the No.64,No.18 and No.29 were the most abundant in fat，the content of linoleic acid and linolenic acid in No.28，No.42 and No.32 were higher than that in others，the 5 principal components extracted could represent 79.96% of the total characters of 23 varieties The key indexes to evaluate the comprehensive quality of walnut were fruit three-diameter，single fruit weight，palmitic acid，linoleic acid，linolenic acid，arachidonic acid，calcium content and protein content，the first five trees were No.1，No.53，No.67，No.32 and No.33 respectively，and the results of principal component analysis ranking and single trait screening ranking showed that the fruit characteristics of No.1,No.53，No.67 and No.32 were excellent.
