Abstract
This study was conducted to analyze the rice yield and grain quality of viviparous germinated seeds caused by long period rainy days. In the yield characteristics, the milled/brown rice rates in two cultivars, Unkwangbyeo and Gopumbyeo were 86.0 and 80.9%, respectively, in viviparous germinated seeds, showing the decreased rates by 3.2 and 6.2%, respectively, as compared to 89.2 and 87.1% in normal seeds. Rice yield in Unkwangbyeo and Gopumbyeo also decreased by 5 and 7%, respectively, in viviparous germinated seeds as compared to normal seeds. Peak viscosity and set back of viviparous germinated seeds were decreased, and the hardness of them was increased compared to normal seeds. Color value (a) of viviparous germinated seeds was 0.90, showing lower value than that (1.65) of normal seeds of Gopumbyeo. The results demonstrated that as the viviparous germinating rate was increased, the grain quality was deteriorated.
