Heterosis and protein profiling through SDS-PAGE in vegetable pea

59 genotypes (14 lines, 3 testers and 42 F₁s) of vegetable pea were studied for heterosis and 17 parents were characterized through SDS-PAGE. PMR-53 × PSM-3 showed highest economic heterosis for most of the traits studied including the yield and yield attributing characters. Seed proteins profiling showed ten groups on different banding patterns in three zones (A, B, C and D). The UPGMA analysis showed that VRP-32, VRP-16 and PMR-53 and PMR-19, Arka Ajit, PSM-4, PMR-62, PMR-31, PMR-60, Nepal Pea, VP-266, PMR-32, E-6, AP-3, Arkel, PSM-3 and VL-7 formed two different clusters. However, PSM-4, PMR-62, PMR-31 and PMR-60; Nepal Pea, VP-266, PMR-32 and AP-3, Arkel, PSM-3 and VL-7 were three different neighbouring groups.
