Pea (Pisum sativum L.) is the second most economically essential winter legume in Pakistan. Yield potential of this crop is low in Pakistan in contrary to other countries and little genetic diversity in the germplasm is the reason for it. This research was planned to determine the genetic diversity in pea genotypes. Twenty pea accessions collected from NARC and AARI were sown following the RCBD design in October, 2022 at the Department of Plant Breeding and Genetic. Data were collected for days to 50% flowering, pod length (cm), pod width (cm), yield per plant (g), plant height (cm), number of seeds per pod, hundred seeds weight (g), seed diameter (mm) and number of pods per plant. For estimating genetic diversity, LSD, and principal component analysis were employed. Significant variation was exhibited by all the studied genotypes. It was concluded by principal component analysis that first five PCs contributed 73.641 % in total variation and the leftover 26.359% was provided by other components. Through this study it is viewed that a great range of genetic diversity is present in assembled accessions which may be used in the breeding of high yielding pea cultivars.
