Tori  (Brassica  rapa  syn. Brassica campestris var. toria) is the most important oilseed crop of Nepal which oceupies about 85 %  of the total oilcrops area. Varietal Improvement has been carried om since National Oilseed Research Program (NORP)  came into  existence.  An  Observation Nursery was planted in 1998199 -1999/2000 at NORP with 24 lines.  Out of them Acc.# 6761 produced highest mean seed yield of 681 kg/ha followed by ACC # 6076 (659 kg/ha) and ACC#6764 (653kg/ha).  In Initial Evaluation Trial  (IET),  highest  mean  seed yield  was produced  by ACC#5738  (825 kg/ha)followedby Surkhet local-B (799 kg/ha)  and ACC# 5692 (797 kg/ha), Over the  locations  and years  (1998/99-1999/2000)  seed yield  results  in coordinated varietal trial showed the variety M-27 as highest yield with 873 kg/hafollowedbyICT-8257(855  kg/ha)  and ICT-9137(811 kg/ha).  While the  check  variety  Pragati produced  mean  seed yield  of 776  kg/ha.  In coordinatedfarmers field trial (CFFT),Surkhet local recorded highest mean seed yield (722 kg/ha)  in Surkhet  condition and Pragati performed  well in Nepalgunj  and  Parwanipur  conditions  and  PT-30  and M-27 performed better in Sarlahi condition.
