This paper presents results of the sweetpotato varietal trials in Central Luzon, as well as the lessons learned from the Central Luzon experience. A large number of promising genotypes was evaluated throughout the Philippines. As of the present, a total of 32 good performing sweetpotato (Sp) varieties have already been released by the National Seed Industry Council (NSIC) as recommended varieties. Results of the regional trials conducted in Tarlac College of Agriculture (TCA) in Camiling, Tarlac revealed that the Sp lines recommended by NSIC were also the good performers in Central Luzon. Of these varieties, VSP-6 was found to be widely adopted by many farmers in the area. Of the 48 SP clones evaluated, only five were found tolerant to viruses. These were J53-7, J60-2, Tres Colores, Tinagimtim and VSP 6.
