↵Analysis of Trait Association and Genetic Diversity in Garden Pea (Pisum sativum L.) Genotypes under Middle Gangetic Plain Region of India

Background: Garden pea is a cool season vegetable crop cultivated extensively throughout the world. Besides nutritional quality it also boosts soils through fixation of atmospheric nitrogen. The most important task breeding to develop varieties with high and stable production, different maturity types resistance against biotic abiotic stresses. To fulfil these objectives, analysis genetic diversity prerequisite choose genetically diverse parents for successful hybridization program know source genes particular trait within available germplasm. Methods: A study was conducted at ICAR-Indian Institute Vegetable Research (IIVR), Varanasi during 2015, using principle component analysis, correlation stepwise regression approaches assess present in 160 genotypes identification use improvement. Result: Based on phenotypic data, three superior VRPD-2, VRPR-15 VRP-292 were identified basis pod yield, number pods per plant, ten weight, length seeds whereas other VRPE-45-1, VRPE-55 VRPE-36 found early flowering. Principle Component Analysis revealed that first four components contributed 85% total variation so given due importance further explanation. Stepwise multiple weight internode best predictors yield plant.
