Abstract : 'Minachikara' is a rice cultivar for feed use. This cultivar was established by the Western Region Agricultural Research Center, NARO in 2016. 'Minachikara' was selected from the progeny of a cross between high lodging tolerance line 'Kanto PL12' and high grain yield rice line 'Kanto-shi 226' named 'Momiroman'. The heading date of 'Minachikara' is three days later than that of 'Hoshiaoba'. Its heading is classified as "middle" in western region of Japan. Its maturity is also classified as "medium-late" The culm length of 'Minachikara' is shorter than that of 'Hoshiaoba'. Its panicle length is similar to 'Hoshiaoba' and panicle number is more than that of 'Hoshiaoba'. Thus, plant type of 'Minachikara' is classified as "panicle weight type". The lodging tolerance is superior and classified as "very strong". The resistance to the white-backed plant hopper is similar to that of 'Hinohikari'. The resistance to rice stripe disease is "resistant". Brown rice yield of 'Minachikara' is 81.6 kg/a, 9% higher than that of 'Hoshiaoba'. 'Minachikara' is expected to contribute to stable production of rice feed grain in the western region in Japan because of its high grain-yield ability, resistance to rice stripe disease and the white-backed plant hopper, and high lodging tolerance.
