Abstract
With 7 figures and 6 tables AbstractGarlic is widely consumed for its culinary and medical benefits. Six hundred and thirteen accessions of garlic and its relatives with diverse origin were evaluated for genetic diversity at eight recently novel simple sequence repeat loci in this study. A total of 113 alleles were detected, the average allelic richness was 14.1 alleles per locus. Using a heuristic approach, a core set of 95 accessions was successfully developed, which showed 100% coverage of alleles with minimum redundancy. The model‐based structure analysis here revealed the presence of four subpopulations in the selected core set, which was basically consistent with clustering based on the genetic distance. The analysis of molecular variance based on this core set showed that between‐population component of genetic variance is <15.6% in contrast to 84.4% for the within population component. Overall FST value was 0.1560, indicating a moderate differentiation among the four groups. These results will provide an effective aid for future allele mining, association genetics, mapping and cloning gene(s), germplasm conservation, and improvement programs.
