ABSTRACT
 
'PRP 2586.1' is a new high yielding, early maturing and red skinned potato clone. It was selected at Hattiban Research Farm of National Potato Research Programme (NPRP), Nepal from a cross between 'Desiree' and 'LBr-40'. It has semi-erect growth habit, medium plant height, light green foliage, medium flowering habit and whitish-pink flowers. Tubers are medium size, red skin, white-flesh, round to oval shape, medium eye depth, medium dormancy and good keeping quality. It is resistant to late blight, early blight, powdery scab and wart disease but susceptible to potato leaf roll virus. It has medium dry matter (19.5%) and specific gravity (1.073) which is higher than 'Desiree' and 'Kufri Jyoti'. Stakeholders preferred its plant character, yield, tuber and cooking qualities. 'PRP 25861.1' exhibited high yield both at on-station and on-farm experiments. Its average yield was 18.4 tha both at on-station and on-farm which is 31.4% and 8.2% higher than 'Desiree' and 'Kufri Jyoyi', respectively. High yielding, late blight resistant, early maturing and red skin characteristics of this clone were preferred by the potato growers and it is expected to be fit in the hill cropping system of Nepal.
