When cooked, the grains have a light and fluffy texture except for Gobindobhog rice which is sticky in texture. Aromatic rice produces more 2-acetyl-1-pyrroline than usual due to a loss-of-function mutation in the BADH2 gene. The BADH2 mutation can be transferred by conventional breeding; it is a recessive trait. Gene editing can be used to induce a similar mutation in ordinary rice, turning them aromatic without affecting other traits. The ''aromatic''

Not all members of the cultivar group are fragrant. The ''aromatic'' group is considered part of the '' japonica'' subspecies.
