Abstract

‘Wolbaek’ is an early-maturing, semi-transparent low amylose content variety developed from a cross between ‘Milkyqueen’ and ‘Geuroobyeo’ by the rice breeding team of National Institute of Crop Science, Rural Development Administration (RDA) in 2000. ‘Wolbaek’ has about 102 days duration from seeding to heading in middle plain, mid-northern inland plain, southern alpine and north-eastern coastal areas. It is about 67 cm in culm length with semi-erect plant type and good canopy architecture. ‘Wolbaek’ has 16 tillers per hill and 59 spikelets per panicle. Its 1,000 grain-weight of brown rice is 21.4 g which is less than that of ‘Odaebyeo’ (26.4 g). The milled kernels look like semi-transparent dull because amylose content of this variety is about 11.6%. This variety shows strong resistance to cold treatment, lodging and wilting. ‘Wolbaek’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 5.13 MT/ha by ordinary culture in local adaptability test for three years. ‘Wolbaek’ may be highly adaptable to the middle plain area, mid-northern inland plain area, southern alpine area and north-eastern coastal areas of Korea.
