This study investigated the genetic diversity of 80 wild bael genotypes () compared to commercial cultivars NB-5 and NB-9, focusing on 16 pomological traits. With the rising temperature impacting perennial fruit crop production and the urgent need for heat- and drought-resistant varieties, bael emerges as a viable option for rainfed areas due to its xerophytic characteristics and ability to withstand high temperatures. Among the collected, wild bael genotype germplasm, JMU-Bael (Sel-27) demonstrated superior traits, including maximum fruit length (12.05 cm), width (11.72 cm), weight (917.65 g), pulp weight (746.81 g), and pulp percentage (81.38%). Correlation matrices revealed significant associations among pomological traits, particularly positive correlations with fruit weight. Principal component analysis (PCA) indicated substantial genetic diversity, with the first two components explaining 63.98% of the cumulative variation. Cluster analysis grouped genotypes into two main clusters, providing insights into their diversity and potential breeding applications. This comprehensive analysis offers valuable insights into the genetic variability and adaptability of bael genotypes under changing climatic conditions in the plains of north-western Himalayan regions.
本研究调查了80种野生印度枳椇基因型与商业品种NB - 5和NB - 9相比的遗传多样性，重点关注16个果实性状。随着气温上升影响多年生水果作物生产，以及对耐热和耐旱品种的迫切需求，印度枳椇因其旱生特性和耐高温能力，成为雨养地区的一个可行选择。在所收集的野生印度枳椇基因型种质中，JMU - 印度枳椇（Sel - 27）表现出优异的性状，包括最大果实长度（12.05厘米）、宽度（11.72厘米）、重量（917.65克）、果肉重量（746.81克）和果肉百分比（81.38%）。相关矩阵显示果实性状之间存在显著关联，特别是与果实重量呈正相关。主成分分析（PCA）表明存在大量遗传多样性，前两个成分解释了累积变异的63.98%。聚类分析将基因型分为两个主要聚类，为其多样性和潜在育种应用提供了见解。这项综合分析为喜马拉雅西北部平原气候变化条件下印度枳椇基因型的遗传变异性和适应性提供了有价值的见解。
