A New Rice Cultivar with High Grain Quality, Adaptability to Reclaimed Saline Soil and Multi-Disease Resistance, “Cheongho”

Abstract

Research Institute (HARI), NICS, RDA, in 2004. This cultivar has a short grain shape and about 123 days growth duration from trans-planting to harvesting under the reclaimed saline area of the south-western and the mid-western coastal plain and Honam plain of Korea.The culm and spikelet number per panicle of Cheongho are similar to those of Nampyeongbyeo, while the filled grain rate is lower thanstandard variety. This cultivar has medium size of brown rice, and shows resistant reaction to bacterial leaf blight, leaf blast and striperoteinand amylose content of rice grain are 6.9% and 19.2%, respectively. The palatability of coked rice of Cheongho is better than Nampy-eongbyeo. The milled rice yield is about 5.53 MT/ha under the standard fertilizer level of the ordinary transplanting cultivation. Cheon-gho would be adaptable for the reclaimed saline area of the south-western and the mid-western coastal plain and Honam plain of Korea.
