Languages : English (eng) Keywords: late  blight,  participatory,  potato  cultivars,  tuber  yield Abstract: Farmers' participatory multi location field experiments were conducted in 201 Ill 2 with the objectives of evaluating late blight disease [Phytophthora infestans (Mont) de Barry] resistant and high yielding potato genotypes. Twenty hvo promising potato genotypes which have been selected through the series of experiments since 2006, were tested in farmers' fields at Dhikure (Nuwakot), Panvanipur (Bara), Belachapi (Dhanusa), Sonpur (Dang) and Kimugaun (Dailekh) involving twa to four farmers in each location. A farmer's field trial ~FF.I') set per farmer, composed af6-15 genotypes, were planted in the plat size ranging from 3 to 6 m during the respective potato planting season. Potato cultivars Desiree and Kufri Sindhuri in Bara, Lalgulab in Dhanusa, MS-42.3 and Cardinal in Nuwakat and Tharu Local in Dang were used as check to compare with test genotypes. Fungicide against any disease was not sprayed throughout the crop period Late blight severity as foliage damage % was recorc(ed at 70-75 days after planting. Crop was harvested at 90-110 days after planting depending an the location and farmers decision. Genotype PRP-266264.01 produced the highest tuber yield (46.67tlha)followed by PRP-266264.15 (41.67 tlha) in Dang, LBr-40 (37.17 t/ha) and CIP-384321.15 (31.83 tlha) in Nuwakot, PRP-266264.15 (17.9 t/ha) in Dhanusa, PRP-25861.1 (26.37 tlha) and PRP 266264.01 (22.66 t/ha) in Parwanipur, BSUP03 (47.05 t/ha) and PRP-266264.01 (44.33 t/ha) in Dailekh. Tuber yields of these genotypes were significantly higher as compared to the yields of respective local check cultivars rangingfram 2.8 to 13.33 tlha.
