Summary

Early segregating generations of an intervarietal spring wheat cross ‘WG 357 × Tobari 66’ was studied to obtain information on the genetics of tiller number, seed size, number of seeds per ear and grain yield, at the Punjab Agricultural University, Ludhiana, Punjab, India. The parental, F₁ F₂, B₁ B₂, bip's, F₃ (parents of bip's), F₃ bulk and F₄ bulk generations were studied to provide analysis of generation means and variance components analysis. Recurrent selection proved to be of limited utility for the improvement of the characters under study. Additive gene action was predominant in the inheritance particularly of yield components and thus simple breeding procedures may be more useful in segregating generations for the improvement of the yield component.
