초록
A new Japonica variety, ‘Keunnun’ was induced from the mutants of N-methyl-N-nitrosourea (MNU) treatment on fertilized egg cell of Ilpumbyeo by a rice breeding team of National Institute of Crop Science, RDA, in 2005. This variety has about 136 days of growth duration from transplanting to harvesting and a midium-maturty with heading date of August 17 in central plain area of Korea. It has resistance to lodging with strong culm and good semi-elect plant type. The number of panicles/hill of ‘Keunnun’ is more than that of Hwaseongbyeo. ‘Keunnun’ has a giant-embryo and richer GABA content than that of Ilpumbyeo after 2 days’ germination in sprouting brown rice. It is susceptible to leaf blast, bacterial blight, virus disease and insect pests. The yield performance of this variety is about 4.52 MT/ha in milled rice in local adaptability test for three years from 2003 to 2005. ‘Keunnun’ is one of cultivars adaptable to central and southern plain area of Korea.
