To ensure the durability of resistance to blast disease in high-quality japonica rice a long-term rice breeding project to develop a few blast-resistant multiline cultivars was carried out from 1987 to 1999. Seven resistance donors were selected based on

“Saechucheongbyeo” is a new japonica multiline for blast resistance, which was composed of equal proportions in seed weight of three near-isogenic lines of two combinations. The recurrent parent, “Chucheongbyeo”, was a high-quality rice cultivar with susc

Anseongbyeo is a japonicaseed weight of three near-isogenic lines of blast resistance. The recurrent parent, Suweon345, was a high-quality and semi-dwarf rice cultivar with susceptability to neck blast. The blast-resistance donors for each liens were SR12
