摘要

"Nunbora" is a new japonica rice cultivar developed from a cross between Iksan433 resistant to bacterial blight and Miyadamamochi, a waxy line, at Honam Agricultural Research Institute, NICS, RDA, in 2006. This cultivar is a short grain shape and about 118 days of growth duration from transplanting "Nunbora" to harvesting under Korean climatic conditions. The milled rice are snow white and glutinuous. This cultivar shows high resistant reactions to the bacterial blight pathogen race K_1~K_3 and blastrespectively. The milled rice yield of "Nunbora" is about 5.34 MT/ha under the standard fertilizer level of the ordinary transplanting cultivation. "Nunbora" would be adaptable for in the middle plain, north middle-mountin plain and Honam plain, and Youngnam plain areas of Korea.
