설갱'은 다양한 전분소재를 육성할 목적으로 1991년 하계에 양질다수성 품종인 일품벼에 돌연변이 유도물질(MNU)을 처리하여 M1세대 697개체를 얻었다. 1992년 하계온실에서 M2세대 113개체를 선발하여 1992/'93 동계 온실에서 M3집단을 육성하였다. M4세대부터는 포장에서 계통선발법에 의해 주요 병충해 및 미질검정을 병행하여 다양한 전분 신소재 계통을 선발 고정시켰다. 중만생종이며 전분의 형태가 아밀로스 함량은 일반 메벼와 같고 투명도는 찰
Seolgaeng' is a new Japonica rice variety developed from an 'Ilpumbyeo' mutant line, N-methyl-N-nitrosourea (MNU) treatment on fertilized egg cell, by a rice breeding team of National Crop Experiment Station, Rural Development Administration in 2001. This variety has about 134 days of growth duration from transplanting to harvesting in central plain area of Korea, a good semi-elect plant type and resistant to lodging with strong culm. The number of panicles/hill of 'Seolgaeng' is more than that of 'Hwaseongbyeo'. The milled rice appearance of this cultivar is an opaque, but it has amylose content (19.3%) similar to 'Hwaseongbyeo'. It is superior to hypae formation of Aspergillus orzyae in the making of fermented rice and amount of pigmentation in fermented rice by Monascus anka that of 'Ilpumbyeo'. This variety showed slow leaf senescence and considerable resistance to viviparous germination. It is moderately resistant to leaf blast and susceptible to bacterial blight, virus disease and insect pests. The yield performance of this rice cultivar is about 5.27 MT/ha in milled rice in local adaptability test for three years from 1999 to 2001). 'Seolgaeng' is adaptable to central and southern plain areas of Korea.
