Abstract excerpt
Flowering time is a critical determinant of regional adaptability. High-yielding rice (Oryza sativa L.) varieties, such as IR64, exhibit an extended vegetative growth period. As a result, IR64 is poorly adapted to high-latitude regions, such as Hirosaki-Aomori in northern Japan where prolonged day lengths and chilling stress during later growth stages induce an excessively late heading. In this study, we...
