Abstract
The present investigation entitled “Genetic diversity analysis in buckwheat using morphological and molecular markers” was undertaken during the kharif 2017 to assess the nature and magnitude of genetic variability and associations among various traits including their direct and indirect effects on seed yield and to identify potential donor parents among the 40 genotypes for their use in future breeding programmes. Data were recorded on seed yield per plant and various morphological traits along with reaction to disease. The analysis was done as per the standard statistical procedures and morphological analysis was done using Mahalanobis D2 statistics and principle component analysis. Molecular analysis was done using NTSYS-pc software and POPGENE software. Sufficient genetic variability was observed for almost all the traits studied. High PCV, GCV, heritability and genetic advance was observed for 1000-seed weight and seed yield per plant. Genotype IC-313149 which was highest yielding genotype was found promising among all the germplasm lines as it also exhibited high number of primary branches per plant, short plant height and 1000-seed weight. Similarity was observed among data for diversity from morphological and molecular analysis. A total of 38 genotypes were found common while comparing molecular clusters and morpho-metric clusters thereby exhibiting the congruence between morphological and SSR data.
