Development, characterization and utilization of genomic microsatellite markers in turmeric (Curcuma longa L)

摘要

Development of a robust set of 18 genomic microsatellite markers from turmeric (Curcuma longa L) and its effective utilization in estimating the genetic diversity of 20 turmeric accessions are described A total of 103 alleles were detected with an average of 5 7 alleles per locus These markers displayed varied levels of polymorphism as evident from its discriminating power ranging from 019 to 070 The UPGMA cluster analysis of genetic distance values resolved the 20 turmeric accessions into five main groups Three sets of genetically identical accessions were detected within the analyzed accessions suggesting a revisit of the germplasm collection strategy based on vernaculai identity The entire grouping pattern of the entities was loose and independent of their geographical origins The,e polymorphic SSR markers would be useful for the population genetic studies and germplasm management of turmeric
