Internode lengths and other characters were measured with the 33 “Daikoku” type dwarfs, 43 of the other type dwarfs, 22 normal rices and 5 giant rices. Heritability and phenotypic and genetic correlation coefficients were estimated from those data. Then it was attempted to clarify the characteristics of the dwarf rice and the significance of using it in rice-breeding program.
