Rayo (Brassica juncea) and Sarson (Brassica campestris var. Sarson) are one of the most important edible oil crop of our  country having the high yield potentiality. They are the most important cash crop of country too which plays very important role in increasing the purchasing power of the Nepalese farmers. Better varieties are  needed for different agroclimatic conditions to increase the productivity of oil crop. With this view ORP has been conducting Varietal investigation work in this crop. During 1995/96, in observation Nursery on Rayo Acc  No. 5750 produced highest seed  yield (953  kg/ha) followed by Acc No. 5746 (627  kg/ha)-Table-1). In CVT on Rayo, Pusa barani produced highest seed yield (630 M/hn) followed  by Kranti (611 kg/ha)and  verdan (602   kg/ha) - Table-2. In Observation Nursery on  Sarson, the highest seed yield was produced by ECS-9138-3 (580.3 kg/ha) followecl by EC6-9138-4 (511.4 kg/ha) and Acc no 5742 (498.1 kg/ha) - Table-11.   IET  on Sarson, Acc No. 28/5 produced hiqhest seed yield (502  kg/ha) followe  by  ICS-9108 (493 kg/ha) - Table-12. In CVT on Saron, the hiqhest seed yield was obtained by PVS-6(775   kg/ha) followed by S-5 (775 kq/ha) and Local sarson(664  kg/ha)-Table-13.
