选取197份制干枣种质作为研究对象,基于层次分析法对其物性、外观和内在品质分析评价,从22项品质性状中选取关键性指标,构建综合评价体系;采用层次分析与灰色关联度相结合的方法对干枣种质果实品质进行全面分析和综合评价,并分别根据等权及加权关联度对其进行排序,筛选优异制干枣种质。结果表明,干枣种质果实品质间存在一定差异,变异系数为5.687%~68.430%;品质性状各指标间存在不同程度的相关性,鲜枣果实粘附性与干枣果实咀嚼度呈显著负相关;采用层次分析法构建了干枣种质果实品质综合评价模型,结合相关性分析结果确定了干枣咀嚼度、干枣单果重、干枣硬度、干枣果皮平展度、干枣果实颜色、干枣可溶性糖含量、干枣可溶性固形物含量7项关键性状为评价干枣果实品质特性主要指标;对197份枣种质进行了品质评价,依据灰色关联分析结果,筛选出15份综合品质优异的制干枣种质。本研究为优良制干枣种质精准鉴定和高效利用提供科学依据。
197 dry jujube germplasm accessions were applied in this study, a evaluation system was developed through of physical, appearance, and intrinsic quality traits, with 22 quality traits initially considered. Key indices were selected to construct the evaluation framework, and a combined approach of hierarchical analysis and gray correlation analysis were deployed to thoroughly analyze and comprehensively evaluate the fruit quality of dry jujube germplasm. Superior germplasm was identified based on weight and weighted correlation values.The results revealed significant variability in physical, appearance, and internal quality traits, with coefficients of variation ranging from 5.687% to 68.430%. Various correlations were observed among the quality traits. A significant negative correlation was observed between the adhesion of fresh jujube fruits and the chewiness of dried jujube fruits. To systematically evaluate the fruit quality traits of dried jujube germplasm, a comprehensive evaluation model was constructed using the Analytic Hierarchy Process (AHP). Combining the results of correlation analysis, seven key traits included dried jujube chewiness, dried jujube fruit weight, dried jujube haedness, dried jujube peel flat range, dried jujube fruit color, dried jujube total soluble sugar content and dried jujube soluble solid content were contentidentified as primary indicators for assessing dried jujube fruit quality. The quality of 197 samples was systematically evaluated, leading to the identification of 15 accessions with outstanding comprehensive quality for dried jujube production.
