Abstract

ABSTRACT Date palm has excellent economic value all over the world. Date palm genotypes grown in Pakistan are diverse in nature. The current study aimed to explore the diversity in 50 date palm genotypes collected from two different research stations in Punjab, Pakistan. The study findings are as follows: Dhakki had the highest fruit weight, pulp weight, fruit width and fruit volume. Jaman had a longer fruit length. Eedel Shah and Begum Jangi had greater fruit thickness and fruit perimeter, respectively. Makran showed a higher fruit area. Dedhi showed the highest stone weight, thickness and volume. Halmain had a longer stone length, and Sundari had an extended stone width. Makhi exhibited a higher stone perimeter and area. The Danda genotype had low weight and a small length of the stone. Begum Jangi and Peeli Sundar had small stone width. Seib and Shado had a higher moisture content in their fruits. The fruits of Baidhar and Khudraw-2 genotypes had the highest dry matter and reducing sugars. Champa Kali and Shakri had higher TSS levels in fruits. Halmain had higher juice pH. The fruits of Pathri and Makhi genotypes exhibited higher non-reducing sugars and carotenoids. In this study, a dendrogram was constructed to cluster 50 genotypes into five different clusters based on their physico-chemical characteristics. The correlation matrix and variable plot revealed positive and negative correlations between fruits traits and their biochemical properties conducive to the improvement of desired traits. Principal component analysis (PCA) revealed that Dhakki, Chohara, Baidhar, Karbalaen and Eedel Shah showed a higher genetic diversity; hence, in the scatter plot and biplot, these genotypes deviated from the centre of origin. Physico-chemical characteristics of data palm genotypes indicated a huge diversity among them, which could help select diverse parents, which is important for different breeding purposes.

理化性质揭示了50种椰枣（Phoenix dactylifera L.）基因型的巨大多样性

摘要椰枣在世界各地都具有卓越的经济价值。在巴基斯坦种植的椰枣基因型在性质上是多样的。目前的研究旨在探索从巴基斯坦旁遮普邦的两个不同研究站收集的50种椰枣基因型的多样性。研究结果表明：达基具有最高的果实重量、果肉重量、果实宽度和果实体积。贾曼的果实长度较长。Eedel Shah和Begum Jangi的果实厚度和周长分别较大。马克兰的果实面积更大。德迪的石头重量、厚度和体积都最高。Halmain的石头长度更长，Sundari的石头宽度更长。Makhi展示了更高的石头周长和面积。丹达基因型具有较低的体重和较小的结石长度。Begum Jangi和Peeli Sundar的石头宽度很小。Seib和Shadow的果实水分含量较高。Baidhar和Khudraw-2基因型的果实干物质和还原糖含量最高。Champa Kali和Shakri的果实TSS水平较高。Halmain的汁液pH值较高。Pathri和Makhi基因型的果实表现出较高的非还原糖和类胡萝卜素。在本研究中，构建了一个树状图，根据50种基因型的理化特征将其聚类为五个不同的聚类。相关矩阵和变量图揭示了果实性状与其生化特性之间的正相关和负相关，有利于所需性状的改善。主成分分析（PCA）显示，Dhakki、Chohara、Baidhar、Karbalaen和Eedel Shah表现出较高的遗传多样性；因此，在散点图和双图中，这些基因型偏离了起源中心。数据棕榈基因型的理化特征表明它们之间存在巨大的多样性，这有助于选择多样化的亲本，这对不同的育种目的很重要。

期刊介绍： Folia Horticulturae is an international, scientific journal published in English. It covers a broad research spectrum of aspects related to horticultural science that are of interest to a wide scientific community and have an impact on progress in both basic and applied research carried out with the use of horticultural crops and their products. The journal’s aim is to disseminate recent findings and serve as a forum for presenting views as well as for discussing important problems and prospects of modern horticulture, particularly in relation to sustainable production of high yield and quality of horticultural products, including their impact on human health.
