Abstract
Demand of high yielding potato varieties with major diseases and pest resistance has been tremendously increasing day by day in Nepal. With the objective of fulfilling this demand, a series of on-station and on-farm studies as Initial Evaluation Trials, Coordinated Varietal Trials and Coordinated Farmers' Field Trials were are continuously undertaken by National Potato Research programme (NPRP) after its establishment (1991). Results from several on-station and On-fam trials conducted during the years of 2004/05 to 2009/010 demonstrated that clones L 235-4 and CIP 389746.2 are superior to check varieties tested for their growth, yield characteristics and farmers' preferences including better resistance level to late blight disease. Therefore, based on their overall performance, clone L 235-4 has been proposed to release as the variety for commercial cultivation for the hills and clone CIP 389746.2 for terai of Nepal, respectively.
