| Research Abstract |
The Japanese rice cultivar “Yamadanishiki” is popular with Japanese sake-brewing. This cultivar is characterized by many traits that are not observed in modern rice cultivars: the opaque structure in the center of rice grains called as “white core” and large grains for the sake-brewing, and late heading date. We conducted genetics analyses of white core and late heading in “Yamadanishiki” using a set of “Yamadanishiki” chromosomal segment substitution lines with “Koshihikari” genetic background.
