Abstract
‘Ondami’, a japonica rice cultivar developed from a cross between Hitomebore having a high grain quality and Sangju27 adaptable to southern mid-mountainous area was developed by the rice breeding team of Sangju Substation, NICS, RDA in 2013. The heading date of ‘Ondami’ is july 27 which is same with ‘Odae’ in Southern mid-mountainous area, mid mountainous, southern alpine area and north-east coastal area of South Korea. ‘Ondami’ has 70cm culm length, 19cm panicle length which is 2cm shorter than those of ‘Odae’ and 78 spikelets per panicle. In reaction to biotic and abiotic stresses, it shows strong resistance to blast, but is susceptible to bacterial blight, virus diseases, and insect pests. The milled rice of ‘Ondami’ exhibits translucent and, relatively clear non-glutinous endosperm, and medium short grain shape. This variety has a higher head rice milling recovery ratio(73.1%) and lower amylose content(18.8%) than that of ‘Odae’. The milled rice yield performance of this variety was about 5.29 MT/ha in ordinary cultivation of local adaptability test for three years. ‘Ondami’ could be adaptable to Southern mid-mountainous area, mid mountainous, southern alpine area and north-east coastal area of South Korea.
