The study determined the performance of PhilRice [Philippine Rice Research Inst.] special purpose rice varieties in terms of yield in Abra under lowland ecosystem. The best varieties would be recommended to rice farmers for growing in the area. Specifically, the study was conducted at the ASIST Research area for two cropping seasons (2007 and 2008). Based on the findings, significant effects were noted on plant height at maturity, number of productive tillers, number of unfilled grains, length of panicle, weight of seeds, harvest index and yield. Moreover, all the varieties were found to be resistant to pest and diseases. NSIC Rc 13, NSIC Rc 17 and NSIC Rc 128 varieties gave the highest yields, which did not significantly differ from each other. These varieties were therefore recommended as planting materials.
