The phenotypic diversity of Black Currant germplasm resources conserved in National Field Genebank for Hardy Fruits (Gongzhuling) China (NFGHF) was analyzed by calculating and analyzing the diversity indices, standard deviations, variances and extreme values of 22 phenotypic traits. Combining with tasting and sniffing, we screened resources suitable for fresh-eating through using fresh-eating fruit evaluation index, weight per 100 berries, soluble solids and flavor of berries . The results showed that Simpson index and Shannon-weaver index of non-numerical traits varied from 0.13 to 0.74 and 0.46 to 2.10. Simpson index and Shannon-weaver index of numerical traits ranged from 0.06 to 0.88 and 0.20 to 3.04. Among the 22 traits of tested resources, diversity indexes of ten traits were higher, including date of first blooming, state of inflorescence, thickness of seedcase, flesh color, berry flavor, flesh texture, weight per hundred berries, soluble solid content of berries, inflorescence length, flower number per one inflorescence. The results indicated that the phenotypic diversity of the black currant resources conserved in NFGHF was more abundant which could meet basically the germplasm resources for the late flowering, fruit property suitable for fresh-eating, processing characteristics and (or) yield formation. The diversities of fruit uniformity and fruit hardness were poor, so we should work hard for the collection and evaluation of the relevant poor diversity resources. Comprehensive analysis of the fruit size, flavor, soluble solids and other properties, as well as tasting and sniffing fruit, we screened out five accession resources suitable for fresh-eating , including 11C-18 (seadling offspring), C82, 11C-22 (seadling offspring), 92/69A, Brodrop, which can provide reference resources for further the evaluation and screening of Black Currant suitable for fresh-eating.
