is one of the main signatures of Perlis with regards to its delightful taste, pleasant aroma and expensive price. authenticity and productivity had become the remarks among the farmers, entrepreneurs, consumers and plant breeders due to the existence of morphological characteristics variation among the fruits and high production cost. Assessment of morphological characteristics of natural population and different tree ages may represent a possible source of important characteristics for development and breeding purposes of . The aim of this study is to evaluate the morphological variation of collected from different location in Perlis and tree age. A total of 150 fruits from 50 trees with three different stages of development (young, middle-aged and old) were characterised using 11 traits; 10 quantitative and one qualitative morphological trait. The ANOVA analyses in combination with Dunn's pairwise and Kruskal-Wallis multiple comparison test able to point out the existence of environmental factor and age influence towards the significant different of identified morphological traits except for Total Soluble Solid (TSS) and pulp percentage. Five clusters of 50 accessions reflect a grouping pattern which not according to neither geographical region nor age. The result of Principal Component Analysis (PCA) using the first two principal components (PCs) provided a good approximation of the data explaining 84.09% of the total variance which majorly contributed by parameters of weight, fruit dimensional characteristics, peel percentage and hue angle, . Preliminary screening of important morphological characteristics which contribute to the phenotypic diversity of is successfully achieved. The findings can be employed by the plant breeders and farmers for the establishment of standard grading of and advancement of breeding crop of in future.
就其宜人的口感、愉悦的香气和高昂的价格而言，是玻璃市的主要特征之一。由于果实存在形态特征变异以及生产成本高昂，真实性和生产力已成为农民、企业家、消费者和植物育种者之间的话题。评估自然种群和不同树龄的形态特征可能是其开发和育种重要特征的一个可能来源。本研究的目的是评估从玻璃市不同地点和不同树龄采集的果实的形态变异。使用11个性状（10个数量性状和1个质量性状）对来自50棵树的150个处于三个不同发育阶段（幼年、中年和老年）的果实进行了特征描述。方差分析结合邓恩成对比较和克鲁斯卡尔 - 沃利斯多重比较检验能够指出环境因素和树龄对除总可溶性固形物（TSS）和果肉百分比之外的已识别形态性状显著差异的影响。50个种质的五个聚类反映了一种既不按地理区域也不按树龄的分组模式。使用前两个主成分（PC）的主成分分析（PCA）结果对数据提供了良好的近似，解释了总方差的84.09%，主要由重量参数、果实尺寸特征、果皮百分比和色相角贡献。成功实现了对导致果实表型多样性的重要形态特征的初步筛选。这些发现可供植物育种者和农民用于未来建立果实的标准分级以及推进果实育种作物的发展。
