Semidwarf with shortened stem, 15 cm shorter than 'Yukara' in ordinary paddy field conditions. Both Yukara and Fukei 71 dwarfs are controlled by gene, d12. Fukei 71 dwarf is sensitive to high temperature (grows to c. 46 cm at 25~30°); number of parenchyma cells tends to decrease longitudinally, thereby broadening culm diameter.
