Abstract: (204 Views)
Pomegranate (Punica granatum L.), one of the oldest cultivated fruits, is renowned for its high nutritional value and medicinal properties. Originating from Central Asia, particularly regions of Iran, Afghanistan, and India, the pomegranate has spread globally, with its high genetic diversity enabling adaptation to varied climatic conditions. This study aimed to evaluate the genetic diversity and relationships among 50 pomegranate genotypes from eight countries—Iran, Afghanistan, Turkmenistan, Syria, Lebanon, India, Yemen, and the United States—spanning three continents (Asia, Europe, and North America) using simple sequence repeat (SSR) markers. Six microsatellite markers were employed, yielding 24 polymorphic loci. The number of alleles per locus ranged from 3 to 5, with an average of 4 alleles per primer pair. The polymorphic information content (PIC) values of the SSR markers varied from 0.28 to 0.46, with an average of 0.38 per locus. Analyses, including Nei's gene diversity index, Principal Coordinate Analysis (PCoA), and Analysis of Molecular Variance (AMOVA), confirmed the presence of substantial genetic diversity within the genotypes of each population. These findings demonstrate the effectiveness of SSR markers in assessing genetic diversity, genotype identification, and DNA fingerprinting of pomegranate genotypes from diverse geographic origins. This study provides valuable insights for pomegranate breeding programs and conservation strategies.
