Dry seeds of twelve linseed genotypes grown at three different locations viz. Palampur, Malan and Kangra of Himachal Pradesh were analyzed for oil, crude fibre, carbohydrate, protein, methionine, β-carotene and total phenol content. Wide variation in various biochemical constituents was observed to range from 38.31 - 47.80% for oil, 11.92- 20.95% for protein, 38.74 - 136.14 mg/g N for methionine, 12.89 - 23.00% for carbohydrate, 5.26 - 8.58% for crude fibre, 12.18 - 32.06 µg/100 g for â-carotene and 609.85 - 1285.99 mg/100g for total phenols at Palampur; from 42.29–52.18% oil, 11.74 - 22.47% protein, 36.90 - 132.21 mg/g N methionine, 12.42–21.10% carbohydrate, 4.72 - 6.95% crude fibre, 12.00 - 25.00 µg/100 g β-carotene and 421.59 - 1342.43 mg/100g for total phenols at Malan and it ranged from 35.64 - 49.69% for oil, 15.18 - 22.80% for protein, 32.76 - 118.43 mg/g N for methionine, 11.28 - 19.88% for carbohydrate, 3.94 - 6.37% for crude fibre, 12.33 - 36.55 µg/100 g for β-carotene and 259.85 -995.64 mg/100g for total phenols at Kangra. The compositional variation among genotypes and locations were significant and ranged from 39.59 - 48.34% for oil, 14.17 - 22.07% for protein, 36.79 - 122.87 mg/g N for methionine, 12.42 to 20.45% for carbohydrate, 5.00 - 6.90% for crude fibre, 14.52 - 27.12 µg/100 g for β-carotene and 430.43 - 1208.02 mg/100g for total phenols. Varietal grading done in order to find out the versatile genotypes revealed that at Palampur, Surbhi, Sweta and PKDL-65 occupied first, second and third positions, respectively, at Malan, Surbhi and BAU-06-17 occupied first and second positions, respectively and LNS-P-5 and NL-119 occupied third position and at Kangra, Surbhi and Sweta occupied first, PKDL-65 and LNS-P-5 occupied second and third positions, respectively. Out of the three locations, Palampur was found to be the ideal location followed by Kangra and Malan in respect of various linseed genotypes.
