为了更好地对葡萄种质资源进行评价研究,丰富数量化、规范化的葡萄种质资源描述系统内涵,对国家果树种质太谷葡萄圃114份鲜食有核葡萄品种的果实主要数量性状(果穗长度、果穗宽度、果穗重量、果粒纵径、果粒横径、果粒重量、果穗大小、果粒大小等)进行了分析研究,结果表明,8个性状变异系数均在17%以上,果粒重量变异系数最大为48.05%;果穗宽度变异系数最小为17.58%;果穗重量的变异幅度最大,为100.0~1030.0 g,变异系数为41.28%;果粒横径的变异幅度最小,为1.3~3.5 cm,变异系数为20.82%。K-S检验表明,8个数量性状的Sig值均大于0.05,符合正态分布。对符合正态分布的数量性状统一用(X-1.2818S)、(X-0.5246S)、(X+0.5246S)、(X+1.2818S)4个点分级,1~5级出现的频率分别为10%、20%、40%、20%和10%。本研究为葡萄种质资源果实性状的描述规范和数据标准化的建立提供了参考。
In order to better evaluate the grape germplasm resources and enrich the connotation of the quantitative and standardized grape germplasm resources description system, the main quantitative traits of 114 varieties of fresh grapevine varieties from the National Fruit Tree Grapevine Ear length, ear width, weight of ear, length of fruit, diameter of fruit, weight of fruit, size of ear, size of fruit, etc. The results showed that the coefficients of variation of 8 traits were above 17% The maximum coefficient of variation of fruit weight was 48.05%, the minimum coefficient of variation of ear width was 17.58%, the maximum variation of ear weight was 100.0-1030.0 g, the coefficient of variation was 41.28%, and the smallest variation of fruit diameter was 1.3 ~ 3.5 cm, coefficient of variation was 20.82%. K-S test showed that the Sig values of all the eight quantitative traits were all greater than 0.05, which was in accordance with the normal distribution. For the quantitative traits conforming to the normal distribution, the frequencies of four points (X-1.2818S), (X-0.5246S), (X + 0.5246S) and (X + 1.2818S) 10%, 20%, 40%, 20% and 10%. This study provides a reference for the description of fruit traits and the standardization of data in grape germplasm resources.
