A study was conducted in Vegetable Research Institute, Faisalabad, Pakistan during 2017-18 and 2018-19 to estimate the genetic variability and correlation among eight different genotypes of pea (Meteor, 9800-5, Pea-2009, 2001-20, Samrina zard, Olympia, 9200-10 and 2001-40). These accessions were sown in RCBD triplicate. Data was collected on morphological parameters i.e. days to 50% flowering, 100-seed weight, yield per plot, plant height, pods per plant, pod length, seed per pod and pod width. The analysis of genetic variability showed high values in genotypic coefficient of variation (GCV 22.42 & 17.81) for pods per plant in bi-annual study of yield related attributes. Maximum genetic advance (36.76% & 20.87%) was also found for pods per plant among all traits in early pea lines. Positive and highly significant correlation (0.8393 and 0.8846) was found with 100 seed weight and pod width during consecutive years (2017-2019). Maximum heritability was found for Pod length (97.95) and days to 50% flowering (96.64) during sequential years. It is concluded that these attributes could be used as selection criteria for the development of early bearing and high yielding varieties.
