Genetic Diversity and Population Assessment of Musa L. (Musaceae) Employing CDDP Markers

Abstract Sixty-six accessions of Musa genus with different genomic groups that consisted wild relatives and cultivated lines were obtained from the International Transit Center, Belgium, for DNA extraction using Cetyl trimethylammonium bromide method, followed by amplification Conserved DNA-derived Polymorphism (CDDP) markers genetic diversity population assessment. A total 421 alleles major allele frequency 2.051 detected reproducible markers. High (GD, 11.093) polymorphic information content (0.918) revealed. The number loci percentage ranged 59 to 66 89.34 100, respectively. Using potential indicators including effective alleles, Nei’s diversity, Shannon’s index, AS group was identified have highest GD, while AAA had lowest GD indices. parameters in ranked as > AAB AAAA AA ABB diploidy BB AB high low based on Total intraspecific interspecific estimate gene flow 0.433, 0.404, 7.113, coefficient differentiation 0.066 obtained, indicating 6.57% among 93.43% within population. Dendrogram analysis produced nine subgroups at similarity index 0.814. These CDDP functional gene-based informative very efficient resolving indices banana plantain genomes. might serve tools selecting suitable training populations breeding conservation species.
