영문 초록

‘Suan’ is a new high quality japonica rice variety developed from a cross between HR20017-B-19-3-1 and Iksan467 in 2003 by the rice breeding team of Rice Breeding and Cultivation Research Division, Department of Rice & Winter Cereal Crop, National Institute of Crop Science, RDA. in 2010. ‘Suan’ has about 132 days growth duration from direct seeding to harvesting in the southern plain including Chungcheong province. The heading date of ‘Suan’ is August 10, faster than that of ‘Nampyeongbyeo’ by 6 days at ordinary season cultivation. Culm length of ‘Suan’ is about 79 cm and tiller number per hill is similar to ‘Nampyeongbyeo’ and spikelet number per panicle is fewer than ‘Nampyeongbyeo’. Ripened grain rate of this variety is approximately 94.6 %, higher than ‘Nampyeongbyeo’ and ‘Suan’ showed higher spikelet fertility than ‘Nampyeongbyeo’ by 12 % when exposed to cold stress. ‘Suan’ has medium size of brown rice and is resistant to leaf blast, bacterial blight and stripe virus disease but susceptible to insect pests. The milled kernel of ‘Suan’ is translucent with non-glutinous endosperm. Protein content of ‘Suan’ is about 6.5%, amylose content and palatability of cooked rice is similar to ‘Nampyeongbyeo’. The milled rice yield is about 5.47 MT/ha, 9% higher under wet-direct seeding, 5.56 MT/ha, 9% higher under dry-direct seeding than ‘Juanbyeo’ and 5.80 MT/ha, 4% higher under the standard fertilizer level of the ordinary transplanting cultivation when compared with ‘Nampyeongbyeo’. ‘Suan’ would be adaptable for ordinary transplanting and direct seeding in the plain areas of south of Chungnam and southwest coastal district of Korea.
