Performance of strawberry (Fragaria x ananassa Duch.) genotypes for quality and biochemical traits under naturally ventilated polyhouse conditions

An experiment was conducted for Evaluation of different genotypes for growth, yield and quality of strawberry (Fragaria X ananassa Duch.) in low cost polyhouse of the department of Fruit Science, College of Horticulture, Mudigere, during 2015-16. The experiment was laid out according to Randomized Complete Block Design with seven treatments replicated thrice. The result reveals that, the number of fruits per plant (22.36) and yield per plant (380.29 g) was recorded maximum in genotype Sabrina. The maximum fruit weight (20.01 g), diameter (3.28 cm) and volume (24.37 cc) was recorded in genotype Fortuna. The fruit quality parameters like total soluble solids was maximum (11.53 °Brix) in Safari, the ascorbic acid content was maximum (73.30 mg/100g) in Sabrina, total sugars was maximum in genotype Fortuna (7.50 %), sugars to acid ratio was maximum (12.20) in Elyana and minimum titratable acidity (0.50 %) was recorded in Fortuna. The genotype Fortuna resulted in maximum Cost: benefit ratio (1: 2.56). Among different genotypes evaluated the Sabrina accounted maximum for growth and yield parameters of strawberry.
