Isolation and characterization of genomic microsatellite markers for small cardamom (Elettaria cardamomum Maton) for utility in genetic diversity analysis.

ABSTRACT: Microsatellite markers in small cardamom (Elettaria cardamomum Maton) were developed using the selective hybridization enrichment method. A total of 140 microsatellite repeats were identified from 270 clones. Primers were designed for 58 microsatellites and 44 primer pairs amplified products of expected size in cardamom. These markers were used for studying the diversity of 20 important small cardamom genotypes, and six markers were found to be polymorphic. The number of alleles ranged from 2 to 7 with an average of 3.6 per locus. Polymorphic information content values ranged from 0.14 to 0.38 based on dominant scoring. The two markers ECM 47a and ECMG 28 generated specific banding patterns for the genotypes MCC7 (Pink tiller) and APG434 (MA18) respectively. Dendrogram illustrated the gene
