In the same year, parent, F1 and F2 pea plants were grown. Estimates of harvest index for parental plants ranged from 0.32 to 0.53. In F1 generation, estimates for harvest index ranged from 0.38 to 0.56, which is on the higher parent or mean parents level. In F2 generation, estimates for harvest index ranged from 0.41 to 0.51. High heritability and low coefficient of variation points that harvest index is an high-hereditary trait. Harvest index in F1 and F2 generations was inherited dominantly and intermediately, depending on combination, and in Poneka x Ramonski 77 hybrid, heterosis occurred. Good general combinators for harvest index were high-yielding varieties Moravac and Karat. Higher estimates of additive variance in comparison to dominance component points on importance of additive gene effect in expression of this trait.
