Study of heterosis for yield and its related traits in Table pea (Pisum sativum. spp. Hortense L.)

Present study was carried out with fifty five genotypes including ten parental lines and their forty five F1s of Table pea (Pisum sativum. spp. Hortense L). The per cent heterosis over mid-parent and superior parent was worked out for yield and yield related attributes. The crosses namely KS-501×E-6, KS-156×E-6, AP-3×E-6 and AP-1×E-6 over superior parent; AP-2×AP-3, AP-4×E-6, AP-2×E-6 and KS-149×AP-2 over mid parent were superior in terms of heterosis along with the mean performance of yield per plant indicating the potential of selected hybrids over existing homozygous parental lines, and exploitation of dispersion of alleles between the parents and mean directional dominance gene action in crop improvement.
