Assessing phenotypic diversity between different landraces of okra (Abelmoschus esculentus L.)

Abstract

The objective of the present study was to investigate the morphological variations among collections of okra landraces in order to improve local varieties in Palestine. Eighteen okra accessions from various locations in the West-Bank region were evaluated for morphological variation. Different sixteen morphological traits were used for okra collection evaluation. The results revealed significant differences in seed color, leaf rib color, stem color, branching patterns, and fruit characteristics. Cluster and similarity analysis classified into two main clusters (I and II) with further sub-clusters. Genetic proximity did not strictly align with geographical boundaries, suggesting that factors beyond location influence genetic similarity. Cluster I exhibited greater diversity, with sub-clusters hinting at potential local adaptation. In contrast, Cluster II was smaller and less diverse, implying potentially distinct genetic origins. These findings provide insights for breeding strategies and germplasm conservation.
