Genetic diversity analysis and population structure in apricot (Prunus armeniaca L.) grown under north-western himalayas using ISSR markers.

ABSTRACT: Investigation of genetic variability and population relationship of 50 accessions of the apricot (Prunus armeniaca L.) was carried out using ISSR markers. The results revealed that the number of alleles per locus varied from 4 to 8 with a mean value of 6.75, and the mean effective number of alleles (Ne) per locus was 1.54. Similarly, the polymorphic information content (PIC) values ranged from 0.464 to 0.424, with a mean value of 0.424. The mean heterozygosity, marker index, resolving power, and effective multiplex ratio (EMR) ranged from 0.001 to 0.002, 0.01-0.06, 1.76-3.84, and 1-4.12. The dendrogram clustered genotypes into two main clades based on their origins. The population structure revealed two sub-populations with some admixtures. The average expected heterozygosity and po
