Paper presented at the 31st CSSP Annual Scientific Conference on 2-7 May 2000 at Batac, Ilocos Norte Hybrid rice promotion is being conducted within the four provinces of Region 2 (Cagayan, Isabela, Quirino & Nueva Vizcaya) and three provinces of Cordillera Autonomous Region (Kalinga, Apayao & Ifugao) starting 1997. The aim is to promote hybrid rice in at least 25% of the 480,000 ha of irrigated rice lands in Northeast Luzon within 5 years. This is done through training, linkages or collaboration, on-farm and media demonstration of the results of research and development undertaken by collaborating agencies. Based on past technology demonstrations (techno-demos) of F1 hybrid rice, the highest yield was experienced in Camalaniugan, Cagayan during the dry season (DS) of 1999 with 12.40 tons/ha, while the best inbred attained a much lower yield of 8 tons/ha. In a 10-ha hybrid compact techno-demo in San Mateo, Isabela, the average yields were 6.85 tons/ha for hybrid rice and 4.00 tons/ha for inbred rice. This potential of hybrid rice to yield much higher than inbred rice has been expected to facilitate the full take-off of the hybrid rice program in Northeast Luzon. However, it is still moving at a snail pace. This is due to the inadequate seed support system which is brought about by several political, social and technological issues. To break through these issues and constraints, PhilRice Hybrid Rice Center (PHC) together with Department of Agriculture-Regional Field Unit 2/Cordillera Autonomous Region Field Unit (DA-RFU 2/CARFU), state colleges and universities (SCUs), local government units (LGUs), non-government organizations (NGOs), Agricultural Training Institutes (ATI), Cagayan Valley Agricultural Resources and Research Development (CVARRD) and farmer-partners in the area, tried to evolve a model/s for specific areas/culture that could lead to the development of a strong seed program on hybrid rice. With the unified efforts of the collaborators, the area planted for F1 hybrid seed production increased four times from 15 ha to 71 ha. Likewise, from a meager 16 ha area cultivated for hybrid rice commercial production during the 1999 dry season, the area was increased to 80 ha in 2000 DS. The yield potential of hybrid rice, its economic viability and other advantages over inbred rice were showcased using the multimedia approach for faster dissemination of hybrid technology. Based on observations, the usual 3-5 day training program was not enough for farmers to internalize the mechanism of hybrid seed production. This was manifested by the frequent calls for PHC staff to provide technical assistance in almost all aspects of hybrid seed production. In response, a season-long training on hybrid rice seed production was developed and conducted/organized in all provinces covered by the PHC. Some 300 farmers and LGU technicians have participated in this program. hybrid rice, inbred rice, multi-media approach, season-long training, seed program, technical assistance, techno-demo, technology advance, technology demonstration INTRODUCTION/BACKGROUNDER the Philippines.

CURRENT STATUS AND ACTIVITIES OF So far, hybrid rice technology in the Philippines has PHILRICE HYBRID RICE CENTER produced two cultivars: Magat (PSB Rc26H) and Mestizo (PSB Rc72H). Both have been bred by the International Rice At the PhilRice Hybrid Rice Center (PHC) at present, 44.17 Research Institute (IRRI). Magat is early maturing at 110 days ha are devoted to hybrid rice commercial production and 37.86 while Mestizo is medium-maturing at 123 days. Magat was ha to seed production. This achievement has been realized with released in 1994, Mestizo in 1997; the national hybrid rice the existence in the national setup of an efficient extension program was launched in 1998. system, of which training, field and media demonstrations are Promotion started in selected provinces that had already major components.

Thus the area for be encouraged to eventually engage themselves in the business hybrid rice for the second techno-demo increased to 15 ha. of hybrid rice. The techno-demo yield for Magat was 5.8 tons/ha, or 15% higher than the best inbred rice. Subsequently, Magat was A.

However, this belief was considered the profitability threshold. Mestizo A/R seed changed to sighs as they were disappointed with the yield of production plots yielded 1.7 tons/ha in the 1997 dry season and Magat at 4.1 tons/ha and Mestizo at 6.4/ha while the best inbred 2.3 tons/ha in the 1998 dry season. yielded 5.8 tons/ha.
