This study was conducted to identify the varietal differences of the viviparous germination and viviparous germinated seed characteristics occurred by continuous rain during maturing stage of rice in 2007. The viviparous germination rates were increased in early and medium-maturing cultivars such as Unkwangbyeo and Gopumbyeo. In the germinating rates using already viviparous germinated seeds were severely deteriorated by 15.3 and 28.2% compared to those of normal seeds as 97.3 and 98.5% on Unkwangbyeo and Gopumbyeo. The regermination rates were increased as the plumule length of already viviparous germinated seeds was shorter, so it is 46.7% in less than 0.9mm plumule length and 12.7% in 1.0~1.9mm.
