%X The analysis of wheat protein data from ten homozygous genotypes grown at six locations in 4 years gave a heritability estimate of 50%, and another of 65% from a sub-set of genotypes of similar maturity. The first-order interactions, genotype x year and genotype x location, were small and nonsignificant. An examination of the variance of a genotype mean indicated that selection in regional testing programs could be based on data from as few as three trials. Laboratory error represented a large proportion of this variance, thus more than one laboratory determination will be necessary.
