The cross F1 population of Ziziphus jujuba‘JMS2’× Z. jujuba ‘Xing 16’and its parents were used as materials. The phenotypic characters of flower and fruit indexes were investigated. The fruit nutrition indexes such as sugar,acid,vitamin C,flavone and total phenol were determined. The genetic diversity,genetic tendency and genetic effect of each index were revealed by correlation,cluster analysis and mixed genetic analysis,it provides reference for further research on jujube cross breeding. The main results are as follows:(1)The distribution range of variation coefficient of numerical characters of F1 fruit of jujube and wild jujube is 8.82%-43.18%. According to the statistics of descriptive characters of fruit appearance,five phenotypes of the same parents,smooth fruit surface,flat fruit shoulder,sepal abscission,nucleation and no red halo of young fruit,accounted for a high proportion in the offspring. The genetic proportion of descriptive fruit appearance traits of male parents in offspring was higher.(2)Cluster analysis of eight indexes of fruit appearance showed that the male parent group accounted for 76.30% of the total. The fruit of male parent group was smaller and round,similar to that of male parent. Cluster analysis of six kinds of fruit internal nutrients showed that the proportion of female parent group was the highest,accounting for 67.12% of the total. The appearance index was more inclined to male parent,and the nutrient content was more inclined to female parent.(3)Sugar,acid,vitamin C,flavone,total phenol and nuclear diameter were separated from each other. The heterosis values of acid,vitamin C,protein,single fruit weight,fruit longitudinal diameter and single kernel weight were negative,and the dominant genetic effect of reducing gene was strong. Mixed genetic analysis found that the optimal model of acid,protein,fruit transverse diameter,fruit longitudinal diameter and core longitudinal diameter was OMG model,without major gene control. Vitamin C,flavonoids,total phenolics,single fruit weight,single kernel weight and kernel transverse diameter were controlled by one pair of additive dominant major genes,while sugar content was controlled by two pairs of additive dominant epistatic major genes.
