In order to identify the suitable varieties of potatoes for Kathmandu valley, four sets of potato
varietal trial with ten promising lines, D!!siree, 388572.11(, LT-5, 389708.3, CEZ 69-1, Kufri
Jyoti. Cruza- 118, 388580.6D, 388578.2D and Cardinal as a check variety were tested in RicePofDio
systems for two consecutive· years, 1999100 and 2000/0 I in Chapagaun of l.alitpur district.
Fertilizers were applied@ 100:100:60 NPK kg/ha along with farmers' dose of FYM (20 tlha) as
a basal application during planting. Potato was p/a~~ted in RCBD with four replications (farms)
with a planting distance of 60 X 25 em Among the tested lines, Cru1:1l- 118 produced the highest
tuber yield (31.2 tlha)followed by CEZ 69-1 (25.83 tlha). Cru1:1l118 produced 58% higher yield
over the farmers' variety ( 19.65tlha). Even then fanners did not prefer this variety because of its
white tuber color, delay maturity, low market price and inferior taste. Considering all the
parameters farmers liked CEZ 69-1, which yielded 31% higher compared to cardinal and because
of its red round tuber shape, good taste, and high market price. This variety surpassed the
standard check Kufri Jyoti (23.54 tlha) in tenns of tuber yield. Harvested tubers of CEZ 69-1 were
saved for seed by the cooperator. farmers. These days, they are growing this variety both in
lowland as well as upla11d conditions, and serving as the seed source of the variety for other
neighboring farmers. This variety should be kept under varietal releasing scheme for Kathmandu
and similar conditions.
