On-station experiment was carried out to identify appropriate potato cultivars for red ant management and increase the tuber yield of potato at Agriculture Research Station (ARS), Jaubari, Ilam, Nepal (2900 masl) during two consecutive years 2018 and 2019. Eight different promising potato genotypes [1. BLR-20 2. PRP296667.2 3. PRP-14267.11 4. PRP-8561.11 5. PRP-016367.7 6. PRP-16567.5 7. Khumal Seto (standard check and 8. Ilam local (Jhyale)] selected from diseased screening nursery were included in the study. Experiment was conducted in previously red ant infected potato field in Completely Randomized Block Design (RCBD) with three replications. The experimental plot size was 5.4 m2 (3m x 1.8m) where planting tubers was done at 60 cm row to row and 25 cm plants to plant spacing. Fertilizers were applied at the rate of 100:100:60 kg NPK/ha and 20 t/ha compost. Well sprouted tubers with weight 30-40 g were planted during the second week of February. The cultural operations were carried out as per the recommendation of National Potato Research Program (NPRP). Harvesting was done during the last week of July. Data on yield attributing traits, late blight disease, number of red ant damaged tubers, maturity days, red ant infested yield and healthy tuber yield were recorded. The potato cultivar PRP-16567.5 produced the lowest red ant score (1.00 red ant score in 1-5 scoring scale), less (0.33 – 1.66 %) red ant incidence percentage, minimum (0.04 – 0. 22 t/ha) red ant infected tuber yield and highest (31.19 – 35.22 t/ha) potato tuber yield followed by PRP14267.11 (1.00 red ant score, 2.00 – 2.16 % red ant incidence percentage, 0.31 – 0. 33 t/ha red ant infected tuber yield and 27.27 – 27.67 t/ha potato tuber yield. Therefore, planting of PRP-16567.5 as well as PRP-14267.11 potato cultivars is appropriate for higher potato tuber yield and lower down red ant incidence at Jaubari area.
