ABSTRACT
An elaborated study on evaluating quality characteristics of exotic fruits belonging to orange group of citrus was carried out at Citrus Research Institute Sargodha. The candidate varieties/cultivars were Rhode Red Valencia, Cara Cara, Amber Sweet, Sun Star and Salustiana. All of these different five citrus varieties evaluated objectively assessing their suitability both for direct consumption and value addition. The work spread over two years (2018and19) produced distinctive results for their commercial exploitation. The attributes in analytical work for fruit quality evaluation were fruit size, weight, peel thickness, peel percentage, juice percentage, rag percentage, total soluble solids (TSS), acidity, TSS/acid ratio, number of segments, and number of seeds, maturity period and degree of granularity. This was ever important study in Pakistan for evaluating the citrus exotic material of latest generation. This endeavour led to the sound recommendation of sweet oranges like Rhode Red Valencia and Sun Star in the two years of study. In case of taste imparting characteristics like TSS, acidity and their respective ratio in the Rhode Red Valencia TSS 11.4 %, Acidity 1.05, TSS/Acid Ratio 10.97, Cara Cara produced TSS 10.95, Acidity 0.74, TSS/Acid Ratio 14.81, Amber Sweet TSS 10.95, Acidity 1.03, TSS/Acid Ratio 11.11, Sun Star TSS 10.54, Acidity 0.95 and TSS/Acid Ratio 11.02 and in Salustiana TSS 10.5, Acidity 1.17, TSS/Acid Ratio 9.00. On the basis of cumulative and maximum presence of quality characteristics Rhode Red Valencia, Cara Cara, and Amber Sweet have been recommended as suitable varieties/cultivars of the future both for direct consumption and value addition.
