열대지역 적응 자포니카 품종의 수발아 특성 = Viviparous Characteristics of Four Korean Japonica Rice Cultivars Adapted to Tropical Region

다국어 초록 (Multilingual Abstract)

To evaluate pre-harvest sprouting(PHS) characteristics of four Korean japonica rice cultivar, ‘MS11’, ‘Japonica1’, ‘Japonica2’ and ‘Jinmi’, which were developed in order to be adapted to tropical region, one Tongil-type, ‘Segyejinmi’ and one indica, ‘IR72’, we examined the viviparous germination rate(VGR) in growth chamber and field condition at International Rice Research Institute, the Philippines and National Institute of Crop Science, Korea, respectively. As results, VGR of three japonica rice cultivars were higher than that of ‘Segyejinmi’, Tongil-type and ‘IR72’, indica. And the VGR of ‘MS11’, ‘Japonica1’ were lower than that of ‘Jinmi’, parent of former two rice cultivar, meaning that it has more improved than its parent. In particular, among japonica rice cultivar, VGR of ‘MS11’ was the lowest both in temperate and tropical regions and that of ‘Japonica2’ was the highest both areas. However, VGR of those cultivar raised, VGR of tolerant two was still higher than that of indica cultivar. These results showed that in terms of viviparity, PHS tolerant ‘MS11’ and ‘Japonica1’ were suitable for and ‘Japonica2’ was inappropriate to cultivation in the tropical regions.
