Abstract
The suitability of potato varieties in a particular location is a matter of economic return in Gandaki province condition. A RFFT consisting of nine genotypes was conducted in river basin conditions of Lahachowk, Kaski and Babiyachaur, Myagdi during the winter season of 2019/20 and 2020/21. The potato genotypes were: CIP 392920.1, CIP 393371.159, CIP 393371.164, CIP 394600.52, CIP 395443.103, CIP 396012.266, Khumal Ujjwal, PRP 336769.1 and Janakdev (check) in the first year and six promising genotypes were selected for the second year. The trial was replicated four times in RCBD where each treatment received 7.2 m2 plot area. The spacing of 60 cm between rows and 25 cm between plants was maintained during planting which accommodated 48 plants per plot. Fertilizers and manure were applied @ 100:100:60 kg N, P2O5, K2O/ha and FYM 20 t/ha, respectively. The tested genotypes were significantly different with each other. The first year results revealed that the genotypes CIP 396012.266 (39.41 t/ha at Lahachowk and 42.23 t/ha at Babiyachaur) and CIP-393371.164 (29.38 t/ha at Lahachowk and 37.29 t/ha at Babiyachaur) were superior with the high yield. Similarly, the second year results showed the same genotypes CIP 396012.266 (38.76 t/ha at Lahachowk and 38.89 t/ha at Babiyachaur) and CIP-393371.164 (29.86 t/ha at Lahachowk and 34.81 t/ha at Babiyachaur) were superior with highest yield. These two genotypes were recommended for farmers’ preference test.
