为探究中国樱桃花和果实的若干性状在后代中的变异和遗传倾向,对中国樱桃‘红妃’(大果,综合性状优良)和‘蒲江红花’(半野生,小果)杂交F1代708株个体的17个花和果实的性状进行了观测和分析。在四川成都,F1群体2021年花期为2月7—17日,盛花期为2月12—14日;果实成熟期为3月30日—4月19日,集中在4月5—15日。F1代的花蕾、花瓣和果实的颜色遗传变异丰富,其中果实颜色有橙红、红、紫红和黑紫等表型。单果质量、果实纵径、横径、侧径、果形指数、果实可溶性固形物含量以及果柄长度均呈正态分布,广义遗传力为60.12% ~ 84.90%。F1代果实质量为1.60 ~ 6.37 g,呈变小趋势,变异系数为20.75%,超中亲率和超高亲率分别为28.81%和2.26%。果实可溶性固形物含量为8.38% ~ 20.53%,呈升高趋势,后代超高亲率为47.60%。果实风味总体表现为甜酸、酸甜和甜。果柄长度表现为超亲遗传的倾向,超高亲率为51.13%,更有利于果实采摘、采后储运以及观赏品种的选育。单果质量与果实纵径、横径、侧径均呈极显著正相关,与可溶性固形物含量呈极显著负相关。

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.
