The goal of the study is to evaluate the major characteristics of pea (Pisum sativum L.) accessions to analyse morphological genetic diversity and identify the candidate genotypes from indigenous gene-pool of Pisum sativum L. The present investigation will be conducted at seed breeding farm, college of agriculture, Jabalpur in randomized complete block design with three replications on 101 pea genotypes for morpho-diversification study of 13 attributing characters. Rabbit eared stipule, compound tendril type, leaflets presence, foliage colour, pod shape of distal part, seed cotyledon colour, seed shape and seed surface has high variation among all germplasm lines. Leaf axil and flower standard petal colour were found purple in 7 lines namely B-22, DDR-54, JP-885 (Purple), FP 14-67, Kalamatar, FP 14-67, FP 14-88 so may be concern that genes governing leaf axil colour also express for flower standard petal colour. Above study revealed the distinct characteristics of germplasms and indicated that morphological variations exist in collected germplasms due to variation in genetic makeup and could be better utilized by breeders in the selection based on their specific requirement for breeding programme along with that this is highly useful study for varietal identification and conservation. The unique germplasms were found; B-22, FP 14-67, FP 14-88 which has stem anthocyanin coloration whereas DDR-23 and FP7-562 lines found normal pod curvature. Further, the unique features can be selected for developing varieties with unique identification may be particularly referred to as indicators to determine an unstable expression of the phenotype of candidate variety.
