Physiochemical Characterization of Citrus Fruits for Identification of Potential Cultivars in Pakistan
Muhammad Agib Shah
Abstract
The present study aimed to analyze the variability in fruit quality parameters from the citrus germplasm unit in Arifwala, Pakistan. Healthy, uniform, and disease-free fruits were sampled at commercial maturity from 10-year-old citrus plants grafted on rough lemon rootstock grown at the Citrus Germplasm Unit during 2021-2022. Twenty-eight cultivars from five citrus groups (sweet orange, mandarin, grapefruit, lemon, and lime) were kept under investigation. Sampled cultivars were subjected to the following fruit quality parameters: physical (fruit weight, fruit diameter, number of seeds per fruit, juice, peel, and rag content) and biochemical (juice pH, total soluble solids, titratable acidity, ripening index, vitamin C, total phenolic contents, antioxidant, anthocyanin, and sugars (sucrose and fructose)) and data was recorded. The results of twenty-eight cultivars demonstrated a significant difference among physiochemical parameters. Rhode Red Valencia cultivars from the sweet orange group; Minniola and Honey cultivars, from the mandarin group, had significant quality traits. Reed and Frost Marsh, from the grapefruit group; Mozero lemon from the lemon group and Persian Lime from the lime group were considered best cultivars with good quality traits. The cultivars identified from the current study were considered valuable from the view of physiochemical parameters.
