Abstract

Varietal characterization of cultivars is essential for the quality of seed production and protection of plant varieties under PPV&FR Act, 2001. Digital image analysis is a fast and reliable method of variety discrimination. Seventy-five varieties of groundnut (Arachis hypogea L.) were studied to know various seed characters like area, perimeter, length, width, length in Y axis, width in X axis, variation, CMRV, circular, elongation, and shape factor. The cluster analysis revealed that the seventy-five varieties of groundnut could be grouped into five main clusters it was easy to characterize TMV-9 in cluster I and CO-1 in cluster 3.
