For rice blast control with multilines, nine near-isogenic lines (NILs) with different complete blast-resistance genes were developed from a leading rice cv. Sasanishiki at Miyagi Prefectural Furukawa Agricultural Experiment Station in Japan. Four of these nine NILs, namely, the Pik, Pik-m, Piz and Piz-t lines were first registered as multilines named Sasanishiki BL (BL) in 1994, and the Pita-2, Pita and Pib lines were added to the registered NILs in 1997, 1998 and 2001, respectively. BL has been cultivated in farmers’ fields in Miyagi Prefecture from 1995, was planted on over 5,000 hectares in 1997. However, its cultivated area is now less than 800 hectares, since Sasanishiki has become unpopular. Resistance of the Sasanishiki multilines to blast has not been broken down for 7 years, and other NILs are also being developed from other leading rice cultivars in our experiment station. New rice multilines are expected to be cultivated for blast control.
