摘要:

以枣(Ziziphus jujuba Mill.)‘JMS2’× 酸枣(Z. acido jujuba)‘邢16’的179株F1群体及其亲本为试材,调查花果表型,测定糖、酸、维生素C、黄酮和总酚等果实营养指标,应用相关性、聚类与混合遗传分析,揭示各性状的遗传多样性、遗传倾向与遗传效应。结果表明,枣和酸枣杂交F1代果实数值型性状的变异系数分布范围是8.82% ~ 43.18%。亲本表型相同的性状有中果面光滑、平果肩、萼片脱落、有核和幼果无红晕等5个,其在子代中占比高;父本果实外观性状在子代所占的遗传比例较高。对果实外观8个数值型性状进行聚类,父本类群占总数的76.30%,果实较小、偏圆。对果实6种营养指标聚类,分4类群,其中母本类群个体占比最高(67.12%);外观指标更偏向于父本,营养内含物偏向于母本。糖、酸、维生素C、黄酮、总酚和核横径6个性状存在超亲分离现象,酸、维生素C、蛋白、单果质量、果实纵径和单核质量6个性状的亲中优势值为负值,减效基因显性遗传效应强。混合遗传分析发现,酸、蛋白质、果实横径、果实纵径和核纵径最适模型为OMG模型,无主基因控制,维生素C、黄酮、总酚、单果质量、单核质量和核横径由1对加性—显性主基因控制,糖含量由2对加性—显性—上位性主基因控制。

Abstract:

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.
