An Experiment was carried out at Pulses Research Center, Ishurdi, Bangladesh for genetic divergence and variability estimate in nine field peas genotype. The trial was conducted randomly in complete block design with three replicas. Observations were recorded on different yield and yield contributing characters. All cultivars showed considerable differences in their performance, indicating the presence of extensive changes in genotypes for most parameters. The highest yield of pods was BFP 11015, followed by Bagha local and Jhikargachha local. The PCV for all the characters was uninterrupted from their respective GCVs. High GCV as well as PCV were observed for the number of pods per plant, 100 seed weight, powdery mildew severity and pod yield, indicating the existence of a broad genetic basis. The High values of heritability with high genetic advance over percent mean were observed for all traits except days to maturity. Plant height and maturity days showed a positive correlation and a significant correlation for seed yield and a negative correlation with a character yield of 100 seed weight. By using principal component analysis first 3PCs were presented variance for 92.37% of the total variation. First, two PC’s were used to build the biplot in which the genotypes such as, 1-IPSA motorsuti-3, 2-Jhikorgachha local, 4-Faridpur local, 7-BFP 11016 are scattered in four quadrants representing the most genetic divergence. Considering the yield, BFP 11015 and Bagha local genotypes are recommended for releasing as a variety and Jhikargachha local, Faridpur local & BFP 11016 are using crossing materials for advanced genetic material
