Out of 9 apple cultivars belonging to spur and colour mutants, Red Spur exhibited the largest fruit size (6.38 cm x 7.69cm) followed by Red Chief (6.37 cm x 7.11 cm) and Vance Delicious (5.95 cm x 6.68 cm). The maximum value of average fruit weight (170.4 g) and fruit volume (193.1 ml) were observed in Red Spur. Maximum value for firmness (1.35 kg/cm2) and T.S.S. (12.50°B) were observed in Red Chief with the lowest acidity in Vance Delicious (0.23%). The highest value for total sugars (8.45%) was recorded in Vance Delicious and for reducing sugars (6.98%) in Red Chief . On the basis of these characteristics, spur type cultivars Red Chief and Red Spur, with maximum yield/tree of 27.4 kg and 24.3 kg respectively, and the colour mutant cultivar, Vance Delicious with an yield of 25.1 kg were suitable for cultivation under mid-hill conditions of Uttaranchal.

Abstract


Out of 9 apple cultivars belonging to spur and colour mutants, Red Spur exhibited the largest fruit size (6.38 cm x 7.69cm) followed by Red Chief (6.37 cm x 7.11 cm) and Vance Delicious (5.95 cm x 6.68 cm). The maximum value of average fruit weight (170.4 g) and fruit volume (193.1 ml) were observed in Red Spur. Maximum value for firmness (1.35 kg/cm2) and T.S.S. (12.50°B) were observed in Red Chief with the lowest acidity in Vance Delicious (0.23%). The highest value for total sugars (8.45%) was recorded in Vance Delicious and for reducing sugars (6.98%) in Red Chief . On the basis of these characteristics, spur type cultivars Red Chief and Red Spur, with maximum yield/tree of 27.4 kg and 24.3 kg respectively, and the colour mutant cultivar, Vance Delicious with an yield of 25.1 kg were suitable for cultivation under mid-hill conditions of Uttaranchal.
