ABSTRACT

Several on-station and on-farm results demonstrated that CIP clones 388572.4k and 388572.1k are high yielder and moderately resistant to late blight and suitable for commercial cultivation in different agro-ecological domains of Nepal. Both of these cultivars are economically profitable in comparison to previously released potato varieties. In the trials, both of the clones were observed medium maturing type taking 100 to 120 days to harvest, which makes the clones fit in existing cropping systems. Main stems were counted average of 3 to 5 per plant and had medium height. Average tuber yield from CIP 388572.4k was 25 to 27 t/ha and that from CIP 388572.1was 24 to 28 t/ha i.e.3 to 6 tons higher than previously released varieties. Tubers had medium dormancy with low dry matter content (average of 17.1%) and medium (1.07) specific gravity. Farmers' preferences demonstrated the potentiality of good fresh market. Based on all of these superior characteristics, clone 388572.4k was released for commercial cultivation as variety "IPY-8" suitable for terai and clone 388572.1k as "Khumal Laxmi" from terai to high-hills on the year 2008.
