To study the inheritance of protein content, two high-yielding wheat (Triticum aestivum L. ssp. aestivum) lines (PH 132 and PH 133) were crossed with the widely grown Indian cv. WL 711 (grain protein 10 percent). Progeny were studied in the F2, BC1F1 and F3 seed (F1, BC1, and F2 generations, respectively). Both groups of crosses produced ratios of 1:14:1, low : medium : high protein content in the F2, and 1:3:0 in the BC1. These figures indicate that two partially dominant genes, which have an additive effect, control grain protein content in these wheat genotypes. The degree of dominance was 0.89 in the cross WL 711 x PH 132. A backcrossing program is now being used to transfer high protein content (from PH 132 and PH 133) into an agronomically superior background (WL 711 and HD 2329)
