Abstract

Walnuts (Juglans regia L.) are nutritionally rich finest nut crop of temperate regions having beneficial effect on the human health. Five different walnut cultivars grown in the temperate region of Himachal Pradesh namely; Kotkhai Selection, Govind, Lara, Partap and Maylannise were selected and evaluated for their physical characteristics, nutritional properties and biochemical composition. Among the fruit physical characteristics, the nut length was found in the range of 29.59 – 38.74 mm, nut diameter (26.72 mm-32.82 mm), nut thickness (28.81mm-34.70 mm), nut weight (7.07 g-12.98 g), kernel weight (3.04g-6.70g), kernel ratio (43.26%-51.62%) and shell weight (4.03–6.84 mm). Arnongst the nutritional properties and biochemical composition of walnut cultivars, high protein content were observed in Kotkhai Selection (20%), followed by Partap (19%) cultivar. varied from ranged The fat content was found to range between 32.25–56.40%, total carbohydrates 8.09–14.0%, moisture content 2.71–3.01%, Totalphenol content renged 32.61–80.00mg/g and Scavenging Antioxidantactivity veried between 40–85%. On the basis of aforesaid characteristics, Kotkhai Selection and Partap suitable for culivation was found to be a superior walnut cultivars in temperate region of Himachal Pradesh, India.
