The study evaluated the agronomic yield of and incidence of late blight and leafminer in selected potato entries across locations/zones and seasons. It also recommended to the National Seed Industry Council (NSIC) the entries for official variety release. Five potato entries grown and selected from preliminary yield trials were evaluated from 2006 to 2009 under different ecoogical zones/elevations: from low mountain zone (1350 masl), mid-mountain zone (below 2000 masl) and high mountain zone (2000 and above masl) for wet and dry seasons. Treatments were laid out following the Randomized Complete Block Design (RCBD) with 40 tubers per replication in all locations and seasons. Entries 380241.17, 2.21.6.2, 676070 and 5.19.2.2 were the best performers in terms of survival, vigor, canopy cover, and leafminer and late blight incidence. These four entries significantly out yielded the check varieties Igorota (processing type), Ganza (newly approved variety) and Granola (table type/farmers variety). Dry matter content was found comparable with Igorota, the check variety. Based on the results entries 380241.17, 2.21.6.2, 676070 and 5.19.2.2 are highly recommended for potato production under low, mid and high mountain zones during wet and dry seasons. These are recommended for the National Seed Industry for variety release.
