The use of the haplo-diploidy for the development of new cultivars in autogamous species has as a consequence that the evaluated lines for selection must be homocigotic. On the contrary, certain residual segregation between the generator lines is foreseen in conventional programmes. Our group is involved in breeding programmes of durum and bread wheat. In this study, lines of both wheat species have been evaluated for the composition of the endosperm storage proteins previously to be released as cultivars. This analysis has the double finality of evaluate the potential gluten quality together with their homogeneity. Our analyses indicate that double-haploid lines present higher homogeneity than the lines obtained by conventional programmes
