Genotype x Envrionment x Management Interactions in Wheat: Year 2

The cultural practices and recommendations that comprise management "packages" have been traditionally developed to apply to all wheat varieties. Yet we know that genetic differences among varieties in their growth habit, maturity, tillering capacity, yield potential, etc. are the rule rather than the exception. Recently Loyce et al (2012) in evaluating wheat variety x management interaction(s) stated "There is therefore a need to modify the classical methods of variety assessment before release". At the American Society of Agronomy meetings this fall there will be a symposium on "Genotype Specific Management". Further, we know from animal systems, that hog rations for breeding stock, for example, are determined largely by the genotype of the animal. In short, it is time to fine tune management recommendations according to wheat genotype.
