Characterization and comparative nutritional study of three strains of Kinnow Mandarin (Citrus reticulata Blanco)

Abstract

The high number of seeds per fruit is a major hindrance in export, fresh fruit consumption as well as in the processing industry. A seedless trait in Kinnow is the utmost desirable characteristic to accelerate the local and export markets. In this comparative study, three strains of Kinnow (normal seeded Kinnow, low seeded and seedless Kinnow) grafted on Rough Lemon rootstock were evaluated for various physico-chemical attributes and nutritional parameters at gene pool center of Citrus Research Institute, Sargodha, Pakistan. Even though conventionally used normal seeded Kinnow performed better in various aspects like fruit size, firmness, acidity, and vitamin C contents. Two new strains of Kinnow mandarin delineate promising nutritional value regarding various physicochemical and proximate analysis parameters like TSS, total sugars, Beta carotene, fat, and ash percentage (11.95%, 7.84%, 63.92 g/100ml, and 2.03% respectively). Seedless Kinnow and low seeded Kinnow strains portray similar results in various citrus quality and nutritional value aspects, anticipating a healthier and progressive domestic and export market.
