To explore the heredity variation and inheritance trend of flower and fruit traits in the F1 progenies of Chinese cherry [Cerasus pseudocerasus（Lindl.）G. Don],17 major traits of 708 individuals derived from true hybrids of two distinct cultivars‘Hongfei’（with large fruit size and excellent comprehensive performance）and‘Pujiang Honghua’（a semi-wild germplasm with small fruit size）were analyzed. Under the climatic conditions of Chengdu City in Sichuan Province,the blooming date of F1 progenies ranged from 7 to 17 February 2021,and mostly between 12 and 14 February. The fruit mature date started from 30 March to 19 April,with high frequency between 5 and 15 April. White,pinkish and pink petal color separation,and orange red,red,purple red and black purple peel color separation occurred in the F1 progenies,showing abundant genetic variation of ornamental phenotypes. Seven important fruit traits,including fruit weight,size,fruit shape index,total soluble solid content and stalk length followed normal distributions,a typical sign of quantitative trait that might be controlled by polygenes. The broad-sense heritability（Hb2）of these traits ranged from 60.12% to 84.90%,and the coefficient of variation（CV）was between 4.77% and 20.75%. The average fruit weight of F1 progenies was 3.71 g（range：1.60-6.37 g）,smaller than the mid-parent value,with the Hb2 and CV value being 82.50% and 20.75%,respectively. The ratio of individuals with fruit weight higher than high parent（HH）and mid-parent（HM）was 28.81% and 2.26%. Ellipse,reniform,near round,heart and oblateness shape fruits were observed in the offspring. The former three shapes accounted for 32.34%,29.10% and 21.89%,indicating a tendency toward ellipse and round heredity. Total soluble solid（TSS）content,ranging from 8.38% to 20.53% and the mean value of 13.03%,had over high-parent tendency in F1 progenies,with the Hb2 value of 76.77%. 47.60% and 76.13% of individuals were higher than that of high parent and mid-parent respectively. As for fruit flavor,sweet-sour,sour-sweet and sweet accounted for 90.95% proportion of all hybrids. The fruit stalk length showed heterosis with an HH value of 51.13%,which was beneficial for fruits harvest,storage and transportation,as well as the cultivation of ornamental cultivars. Correlation analysis indicated that the fruit weight was positively correlated with the longitudinal,transverse and lateral diameters（r = 0.880**-0.946**）,but negatively correlated to the TSS content（r =-0.103**）. These results will provide a basis for the prediction of offspring' main economic traits and parental selection in breeding programs of Chinese cherry.
