Hybrid rice technology has been recognized as a viable approach in increasing the genetic yield. Introducing some hybrid rice varieties in the Nigerian Niger Delta region will ultimately increase national rice production, and ultimately attain self-sufficiency and food security enshrined in the country’s National Rice Policy. Field studies were carried out to evaluate the performance of four Chinese hybrid rice varieties (9you 418, 9you138, Xudao151and Xuyou601) in comparison with FARO 15, the best conventional variety in the Cross River rain forest zone of Nigeria. Result obtained showed comparative superiority of FARO 15 to the hybrids in all growth and yield components assessed. FARO 15 was taller (140 cm) with more productive tillers (11.0), had highest number of 166 spikelets plant -1 , 156.17 filled grains panicle -1 , highest filled grains ( 92.17 % ), highest 100-grain weight of 2.63g and the highest paddy yield of 5.021 t ha -1 . Despite the comparative poor performance of the hybrids, Xudao151came close to FARO 15 with grain yield of 2.987t ha -1 , indicating that further agronomic investigations on this promising hybrid could improve its yield substantially and maximize the benefits of hybrid rice cultivation in the region.
