Abstract

The conditions of distinctness, uniformity and stability (DUS) must be met in order for a new variety to be registered or protected. DUS testing ensures that a novel variety is unique from other existing varieties and that the farmers will produce a variety with consistent traits that will remain intact in subsequent generations to follow. However, DUS testing does not provide information about genetic diversity as a result, cluster analysis was performed.

Twenty-two farmers’ varieties (FVs) of pea (Pisum sativum L.) were collected from Vindhyan zone of eastern Uttar Pradesh and were grown in randomized block design with three replications during rabi 2019-20 and 2020-2021. FVs were characterized according to DUS guidelines of the PPV and FRA, 2001 and were subjected for Agglomerative cluster analysis by using Ward’s method.

All the characters were found uniform and stable in their expression in consecutive two seasons. PKKK-227 and PMKK-232 were similar to each other, while rest FVs were found distinct. The varieties were grouped into 5 clusters, among which maximum genotypes (8) were in cluster II and minimum genotypes (2) were in cluster V. Cluster I, III and IV had 4, 3 and 5 farmers’ varieties respectively. FVs in cluster II are more or less similar to each other; hence they have a common ancestor. Ramaipur had maximum diversity among the villages of Vindhyan zone.
