Genetic improvement of Pisum sativum L. using diallel system

Pisum sativum L. is of great importance because it is suitable not only for fresh consumption, but it provides considerable raw material for the canning industry. It can be fitted well into the crop rotation; it is eco-friendly, after the pea the soil is enriched with nitrogen. Breeding of peas has been substantial to produce new genotypes with better qualitative and quantitative traits to suffice the demand of the market. In generally the diallel crossing has been used for getting the most completely genetic information about the inheritance of quantitative traits of the genotypes. Combining ability studies were made in F1 generation for four yield-determining quantitative traits: pod per plant, seed per pod, pod length and plant high. F3 generation was genetically characterized and genetic advancement was tracked by evaluations of subsequent generations.
