‘Saegyejinmi’: Multiple Disease Resistance and Mid-late Maturing Tongil Type Rice Cultivar

Agriculture is being forced into marginally productive areas due to utilization of more land area for housing and industrial activities. Furthermore, climate changes also become a primary restriction factors for food security. To cope against these changes, a Tongil-type rice cultivar ‘Saegyejinmi’ derived from a cross of ‘Milyang160 (Areumbyeo)’ and ‘Yongjubyeo (Suwon333)’ which is high yielding and good eating quality as well as multiple deasease resistant was developed at Department of Functional Crops, NICS, RDA in 2008. The pedigree name of ‘Saegyejinmi’ is YR20798-6-3-1, which was designated as ‘Milyang 223’ later. Heading date of ‘Saegyejinmi’ is August 17 as mid-late ecotype unlike other early ecotype of Tongil-type cultivars. The culm length of ‘Saegyejinmi’ was 82 cm which is 10 cm higher than that of ‘Dasanbyeo’. ‘Saegyejinmi’ shows multiple resistances to leaf blast, all races of bacterial blight (K1, K2, K3, K3a), and rice stripe viruses. It is susceptible to plant hoppers. The taste and texture of cooked ‘Saegyejinmi’ were similar or even higher compared to that of japonica grains. In the local adaptability test, the potential milled rice yield of ‘Saegyejinmi’ was about 7.01 MT/ha at 18 kg/10a of nitrogen fertilizer level. ‘Saegyejinmi’ is suitable for mid and southern plains of Korea.
