Yield and physico-chemical performance of different kiwifruit cultivars in Kumaon hills of Uttarakhand

Abstract

An experiment was conducted to evaluate the yield and physico-chemical performance of five kiwifruit cultivars viz., Monty, Hayward, Allison, Bruno and Abbott in the year 2016. The highest fruit yield (70.28 kg/tree), fruit length (71.73 mm), fruit weight (61.66 g) and fruit volume (60.41 cc) were recorded in cultivar Allison. The lowest fruit yield (25.12 kg/tree) and fruit length (52.20 mm) were recorded in Hayward, while lowest fruit weight (53.84 g) and fruit volume (52.70 cc) were estimated under Monty. The fruit firmness was found highest (7.53 lb/in2) in Hayward, while the lowest (2.37 lb/in2) in Monty. The highest T. S. S. (13.50 °B) was found in Allison, while lowest (11.67 °B) in Abbott, whereas highest acidity (2.39%) was recorded in Monty and lowest (1.89%) in Abbott. The highest ascorbic acid (110.47 mg/100 g), carotene content (354.33 µg/100 g) and total anti-oxidant activity (37.04 mMTE/L) was recorded in Bruno, while lowest ascorbic acid (89.52 mg/100 g) and total anti-oxidant activity (31.14 mMTE/L) were recorded in Hayward. The lowest carotene content (218.56 µg/100 g) was recorded in Monty. The highest reducing (7.04%) and total sugars (8.31%) were found in Monty, while lowest reducing (4.56%) and total sugars (5.10%) in Hayward. Therefore, Allison followed by Bruno cultivar of kiwifruit needs to be popularize in the region in view of yield and physicochemical performance.
