Dee-geo-woo-gen is a spontaneous dwarf mutant of rice which is characterized by dwarf plant habit ( 60cm; half than the traditional tall varieties), stiff and erect leaves to ensure maximum exposure to sunlight, photo insensitivity and lack of seed dormancy. A cross between Dee-geo-woo-gen and tall drought-resistant variety produced Taichung Native-1, the first semi-dwarf rice variety.
