  • 'Sinunbong 1' is a japonica rice cultivar developed from the cross between "Sangjubyeo", high yield cultivar and 'Unbong 17', cold tolerance at Honam Agricultural Research Institute (HARI), NICS, RDA, in 2005. This cultivar has a short grain shape and about 111 days growth duration from transplanting to harvesting in Korean climate condition. This cultivar shows high resistant reaction to the blast, but susceptible to bacterial blight and strip virus. This variety has cold tolerance, compared to Odaebyeo. The milled kernels of 'Sinunbong 1' are translucent with non-glutinous endosperm. It has about 19.2% of amylose content and better palatability of cooked rice compared with 'Odaebyeo'. The milled rice yield of 'Sinunbong 1' is about 5.46 MT/ha under the standard fertilizer level of the ordinary transplanting cultivation. 'Sinunbong 1' would be adaptable to the northern plain, mid-mountainous, southern mountainous of Korea.
