Thirty three genotypes of chickpea including 9 kabuli and 24 desi types were evaluated for distinctiveness based on 13
qualitative and 7 quantitative morphological DUS descriptors. In desi type, only 4 traits were polymorphic whereas, in
kabuli type, only 3 were polymorphic. Identification profiles were generated on the basis of grouping and essential characters
prescribed by DUS Guidelines of PPV & FR Authority. However, out of twenty four desi genotypes, distinct profiles could
be created only for sixteen varieties and in kabuli type, only three out of nine genotypes could be singled out individually.
Image analysis using scanned images of flowers of desi types successfully complemented the morphological descriptors to
establish genotypic identity based on differences in the petal colour intensity and venation pattern. Genetic parameters for
all the quantitative traits revealed less environmental influence on the characters expression thus, signifying their utility in
the varietal characterization. Seven agro-morphological traits were used to assess the variability using Ward’s Minimum
Variance Cluster Analysis. Thirty three cultivars from both types were grouped into four cluster each, however, none of the
clusters contained genotypes with all the desirable traits, which could be directly selected and utilized.
