This study determined the adaptation of upcoming hybrid rice varieties under Tabuk condition in Kalinga Province. The Randomized Complete Block Design and the following treatments were used in the study: T1-HLX1, T2-HLX2, T3-HLX3, T4-HLX4, T5-HLX5. Results showed that T3 produced the highest number of tillers and T4 the lowest. T3 produced the longest panicle at 22.64 and T2 the shortest at 21.97. T2 yielded the highest number of filled grains per panicle with a mean of 26.7 and T1 the lowest at 3.6. Unfilled grains per panicle were highest in T4 (136.25), but lowest in T2 (90.5). On the degree of spikelet opening, T5 showed the widest spikelet opening and T2 the closest. T2 had the heaviest grains and T5 the lightest. On the return of investment, T2 obtained the highest at 533.94% while T5 had the lowest at 25.50%. T2 has been recommended for planting in Kalinga during the wet season based on its performance-highest number of filled spikelets, heaviest grains and highest ROI [return on investment] (533.94%) compared to the other treatments. However, a similar study should be conducted during the dry season for verification purposes.
