Evaluation of Physico-chemical Characters of Different Genotypes of Karonda (Carissa carandas L.)

Abstract

The current study was conducted in 2021–2022 at the Post Graduate Laboratory of the Department of Horticulture, School of Agriculture, ITM University Gwalior (M.P.). The presents study was entitled to Study onCollection and Evaluation of Karonda (Carissa carandas L.) Genotypes in Gwalior and Etawah Region. In the present study, 20 Karonda genotypes collected from two region viz. Gwalior and Etawah. The experiment was laid out in Complete Randomized Block Design (CRD) with three replications. The results highlighted that, the genotype GKr9 produced maximum fruit weight (3.96 g), fruit width(18.47 mm). The genotype GKr10, GKr11, GKr12, EKr19 and EKr20 produced highest number of seed per fruit (3.0) and seed weight (0.50 g). However, the genotype EKr14 had maximum total soluble solids (6.17°Brix). However, the genotype EKr19 produced highest TSS: acid ratio (4.95) and ascorbic acid (40.76 mg/100g). The genotype GKr12 and GKr13 had maximum pH of the juice (6.43) and acidity (2.44%). Whereas, the genotype GKr8 had maximum reducing sugar (16.64%) and total sugar (45.20%). Thus, on the basis of present study it may be concluded that the genotype GKr8, GKr9 GKr10, GKr11, GKr12, GKr13, EKr14, EKr19 and EKr20 superior among all the genotypes.
