Abstract

This experiment was conducted to determine the general and specific combining abilities and heterosis for grain yield and yield associated traits in pea as a source of protein through line x tester analysis. Grain yield and its inheritance were carried out for investigation through a 12 x 3 line x tester analysis. Experimental materials comprising 15 parents and their 36 hybrids. The materials were planted in a randomized block design with three replications. The general combining ability and Specific combining ability effects were significant indicating the presence of both additive and non-additive types of gene actions. Heterosis was determined as the superiority over mid parent heterosis as well as better parent (HBP). Grain yield showed highly significant heterosis ranging from -36.29 to 8.77and relative heterosis ranged from -25.85 to 13.19 respectively.
