A novel mutant with triple the dietary fiber content in white rice

Dietary fiber has high functional value in relation to gut flora. We searched for a high-lysine mutant of the most popular rice cultivar in Japan, ‘Koshihikari’, as a route to a higher dietary fiber content like a success case in new barley cultivar, ‘Beau-fiber’. We found several promising high-lys...

description Dietary fiber has high functional value in relation to gut flora. We searched for a high-lysine mutant of the most popular rice cultivar in Japan, ‘Koshihikari’, as a route to a higher dietary fiber content like a success case in new barley cultivar, ‘Beau-fiber’. We found several promising high-lysine mutants with high dietary fiber content. One of these, ‘WFE5’, has three times the dietary fiber content in white rice. Two rounds of backcrossing to Koshihikari produced a near-isogenic line with a high fiber content. The line’s agronomic traits were close to those of Koshihikari except for yield and eating quality. As these two traits are critical, we discuss how to improve them.
