Abstract
Two hundred and sixty three genotypes of Pisum sativum were analyzed for numerical taxonomy to investigate inter and intra-cluster distances and superior accessions were identified with broad genetic base. High variance for grain yield per plant, biomass per plant and pods per plant indicated the scope of improvement through simple selection for high mean values for these traits. Based on average mean variance, five clusters with varying degrees on inter cluster distances were observed. Thirty-seven accessions of cluster-IV were early in maturity and high yielding, whereas 66 members of cluster-V were late in maturity and low yielding. Among selected genotypes, some exhibited better performance for more than two characters, hence these are suggested to evaluate under wide range of climatic conditions.
