Development of panicle blast on Pb1-mediated resistance gene cultivars. Rice blast index of cultivars grown in an experimental paddy field at the Aichi Agricultural Research Center field in 2014. The cultivars, Aichi67, Tsukinohikari, Hoshijirushi, K209 and Kanto HD2 were evaluated in the field. The resistances of Tsukinohikari and Aichi 67 were stronger than that of Kanto 209 and Hoshijirushi in the full heading stage. The heading date of Aichi67, Tsukinohikari, Hoshijirushi, K209 and Kanto HD2 were 21st, 20th, 20th, 19th and 22nd of August, 2013, respectively. The Kanto HD2 cultivar was the negative control for the rice panicle blast resistance
