Fifty hill wheats along with three checks (Kalyansona, Sonalika and VL 421) were evaluated to work out phenotypic and genotypic coefficient of variations (PCV, GCV) heritability. genetic advance (GA) and path coefficients for 12 matric traits. High estimates of PCV, GCV, heritability and GA indicated substantial genetic variability and scope for selection for grain weight/spike, 1000 grain weight, grains/spike, grain yield/plant, harvest index, biological yield/plant, spikes/plant and tillers/plant in the experimental material. There was little variability and scope for improvement through selection for days to 50 per cent flowering, days to maturity, spikelets/spike and plant height. Path coefficient analysis revealed importance of harvest index, biological yield/plant, 1000 grain weight and spikes/plant for improving grain yield/plant.
