3. The su_x found in a Brazilian commercial variety (Maize Genetics Co�p. News Letter No. 22. 1948), when crossed with a white flint strain and selfed, gave a ratio of approximately 6 normal : 1 su_x. Seeds, su_x, of this cross were sown and the plants crossed with su₁ tests. The ears secured contained: (a) All seeds apparently normal, (b) all seeds sugary or "pseudo" sugary or, (c) segregation of approximately 1 normal : 1 sugary or "pseudo". Other combinations will be investigated this summer (1950).
