Effects of non-allelic interactions of O2 and SU2 mutant genes on grain biochemical composition in various corn inbreds

The use of combinations of non-allelic mutant genes of the maize endosperm structure creates opportunities for improving the quality of corn grain in comparison not only with forms of the common type but also with monogenic endospermic mutants. In this study, the effect of a combination of mutant ge...
