The typical dwarf varieties of rice vary in height from 10 cm. to 75 cm. They are characterized by shortened internodes, short and broad leaves and small compact panicles. Crosses of dwarf with normal varieties have generally shown that they are mono-recessive (Parnell, Akemine, Nagai and Yamaguti). Sugimoto, however, reports a dominant dwarf. Except for Akemine's work, there have been no attempts to determine the number of genes for dwarfing in rice. He crossed two dwarfs, differing in height, and obtained tall F1 plants. In F2 the segregation was 9 tall; 3 first type of dwarf ; 3 second type of dwarf; 1 third type of dwarf ; the last phenotype being the result of segregation.
