An Early-Maturing, Blast Resistant and Low Amylose Rice Variety ‘Seolbaek’

The ‘Seolbaek’ is an early-maturing low amylose variety developed from a cross between ‘Suweon460’ and ‘Geuroobyeo’ by the rice breeding team of National Institute of Crop Science, Rural Development Administration (RDA) in 2000. The ‘Seolbaek’ has about 100 days duration from seeding to heading in middle plain, mid-northern inland plain, southern alpine and north-eastern coastal areas. It has about 60 cm in culm length with semi-erect plant type and good canopy architecture. This variety has 13 tillers per hill and 81 spikelets per panicle. Its 1,000 grain-weight of brown rice is 20.7 g whereas less than that of ‘Odaebyeo’ (26.3 g). The milled kernels look like dull because amylose content of this variety is about 10.0%. This variety shows strong resistance to cold treatment, lodging, and wilting. The ‘Seolbaek’ shows resistant to blast disease but susceptible to bacterial blight, stripe virus and insect pests. The milled rice yield performance of this variety is about 4.96 MT/ha by ordinary culture in local adaptability test for three years. This variety may be highly adaptable to the middle plain area, mid-northern inland plain area, southern alpine area and north-eastern coastal areas of Korea.
