Molecular characterization of common bean accessions using microsatellite markers

ABSTRACT The common bean, a legume of significant economic importance, is renowned for its extensive genetic variability. It crucial to comprehend diversity, analyze population structure, and understand relationships among commercial classes accessions facilitate improvement. This study aimed molecularly characterize 143 bean by employing 25 SSR molecular markers. objectives were estimate cluster populations using the UPGMA PCoA methods. A total 105 alleles amplified microsatellite loci, observed heterozygosity was lower than expected across all indicating inbreeding within populations. Among 22 highly informative, demonstrating their effectiveness polymorphism in detecting diversity. variability found be highest, while variation between lowest. analysis structure revealed presence three with notable rate gene introgression. categorized into 15 groups, but they did not form distinct clusters based on geographic regions or pool. first two principal coordinates accounted 13.95% accessions. markers employed effectively detected accessions, revealing that diversity correlated distribution this study.
