The allelic relationships among three uzu or semibrachytic mutant genes ( uz , uz2 , uz3 ) were studied. The coleoptile length and projection on the coleoptile were used as the representative traits of the uzu gene ( uz ). F 1 and F 2 data of five crosses showed that the three uzu‐type mutants are controlled by the same gene ( uz ), or at least they are allelic to each other. The previous conclusion that there were three different uzu genes ( uz , uz2 , and uz3 ) could be explained as follows: the character plant height used by the previous workers was not only affected by the uzu gene but also by pleiotropic effects of L vs. 1 for spike density and probably other modifier(s) as suggested by Takahashi (1951. Ber Ohara Inst. Landwirtech. Forsch. 9:383–398).
