Genetics of Protein Content and Proteolytic Activity in Wheat

Additive and nonadditive types of gene action were found to be operating for the inheritance of grain protein and proteolytic activity in wheat. Some degree of overdominance was observed for both these factors. Presence of assymetry of dominant and recessive genes was observed for protein inheritance. A small group of genes were found to be controlling the inheritance of grain protein and proteolytic activity. The heritability was found to be 33⋅37 per cent, for protein content and 53⋅33 per cent, for proteolytic activity. The good general combiners for protein content were ‘Hy. 633’, ‘J.N.W. 137’ and ‘H.D. 1999’. The cross ‘Hy. 633’ × ‘H.D. 1999’ could be studied further for exploring the possibilities of obtaining high yielding and high flour protein hybrids.
