Rol genes-rolA, rolB, and rolC-have been used in some plants to produce new genetic variability for agricultural traits. This study analyzed the effects of transferring rol genes to increase panicle-bearing tillers and induce early flowering in indica rice. The rolC gene was transferred to indica variety Heera to increase the number of panicle-bearing tillers, which are inherently low in this variety. Due to the transfer of this rol gene, two plants showed a multiple tillering habit after 10 d of germination, 9-12 tillers per plant compared with only 2-3 tillers in control plants. Increased grain production approached 160%. The transfer of rolA gene to indica varieties Kalonunia and Basmati 385 to induce early flowering is also briefly discussed
