Abstract:
Pea (Pisum sativum L.) an extremely self pollinated, annual herb of Fabaceae family comprising each wild (Pisum fulvum & Pisum elatius) and cultivated species (Pisum abyssinicum). A glorious supply of dietary protein particularly essential lysine amino acid in its pods. Offseason peas holds nice economic potential however suffer on productivity front. Yield could be a complicated polygenic trait; its improvement is feasible through identification of contributory traits. With the aim to find out yield contributing traits thirty one diverse pea genotypes were morphologically evaluated. Evaluation was done in mid hill conditions of western Himalayan range during Rabi season of 2014-15. Loading of various variables supporting first principle component indicated that node at which first flower appear (NF), Number of pods per plant (NP), Number of seeds per pod (NS) and yield (Y) were the main components of divergence between 31 pea genotypes. Multiple linear regression model indicated that yield per plot might be well predicted with assistance of variables like number of pods per plant (NP), weight of 100pods (WH).
