Conteúdo: 	THE studies of the inheritance of dwarfness in common wheat were summarized by Kihara in 1938. Since the data obtained by different workers varied greatly from one another, the interpretations were also different. The results were explained on the basis of the following hypotheses: (a) There are two dominant complementary factors for dwarfness D1 and D2; (b) a factor I or N, when in a dominant condition, inhibits the action of D1 and D2; and (c) a second factor, E, in a dominant condition inhibits the action of I. In the fall of 1939, the writers obtained dwarf wheat plants among F2 segregates of two varietal crosses. In subsequent years the frequencies of dwarf plants were studied in some other crosses and backcrosses. These results could not be accounted for Satisfactorily by the previous hypotheses. The data obtained have been summarized and a genetic interpretation has been suggested.
