Based on the findings of the study, the different hybrid rice varieties evaluated had significant effects on plant height at maturity, number of days to maturity, number of tillers, number of productive tillers, number of filled and unfilled grains, length of panicle and yield. RGBU010A X SL8R is therefore recommended as planting material among hybrid rice varieties because it produced favorable yield, produced more productive tillers and filled grains, produced longer panicles, heavy seeds, high harvest index and are accepted by consumers. In the absence of this variety, RGBU02A X SL8R, RGBU003A X SL8R and RGBU0132A X SL8R may also be used as planting material.
