1. Two previously undescribed characters of N. tabacum are described and studied genetically. The yellow plant color appears to be distinct from similar deficiencies heretofore reported. It is not to be confused with the Burley character in White Burley tobacco. 2. Green color is dominant to yellow color. 3. Normal green is dominant to glaucous or "Ceniza". 4. Green and yellow are differentiated by a single factor pair which is designated Yy. 5. Normal green and Ce or glaucous plants are differentiated by two factor pairs; therefore segregation occurs in the proportion of 15 normal green to 1 glaucous (Ce). These are designated by Ce1 ce1 Ce2 ce2. 6. The factors for glaucous and for yellow are inherited independently of each other.
