Outline of Final Research Achievements

Rice plants are affected by surrounding temperature. It results in injury of pollen fertility, delay of development, seed set, and defective kernels. Countries like Japan extended from north to south have required broad range of heading data by which varieties adapted to different areas. In northern areas, chilling tolerance and blast disease resistance have been also key traits to improve varieties and succeeded to some extent. However, current climate changes results in unpredicted damages to rice cultivation such as chalky grain and cracked grains. Recently relatively higher temperature at ripening stage damaged rice grains and reduced the quality.Cracked grain is a major factor of defective kernels in east Japan. It leads grains to lower grade. Koihonoka has bred as Basmati370 as one parent and shows higher tolerance. We developed molecular markers to enable rice breeders efficiently select progeny tolerant lines.
