Investigation of intraspecific diversity in Capsicum chinense using morphological and molecular markers

Published on

Sixty accessions of Capsicum chinense were investigated
to reveal the genetic diversity based on morphological traits
along with ISSR based molecular markers. Genetic distances
for morphological traits and ISSR markers respectively
ranged from 1.41 to 8.60 and 0.05 to 0.49. Fourteen ISSR
markers showed mean of 53.84% polymorphism. The Mantel
test revealed low correlation (r=0.34) between the genetic
distances based on morphological and molecular markers.
All the accessions of Capsicum chinense found genetically
diverse which can be used for future crop improvement
