Genetic Analysis For Seed Yield, Seed Water Absorption Capacity and Protein Content in Pea (Pisum Sativum L.)

The present study on the nature of gene action controlling yield, seed water absorption capacity and protein content in pea (Pisum sativum L.) in two crosses (T163 × EC33866 and T163 × 485) shows epistatic component for seed water absorption capacity and protein content. Greater contribution of i type epistasis than j and i types has been observed for protein content in both the crosses and for grain yield in cross T163 × EC 33866. However, j and i type epistasis was observed for seed water absorption capacity in both the crosses. in the presence of i type epistasis, the additive component was more important for grain yield in cross T1 63 × EC 33866 and for protein content in both crosses, while dominant component was present for seed water absorption capacity only in cross T163 × EC 33866.
