Abstract
A comparative study was conducted from 1988 to 1990 at National Agricultural Research Centre, Islamabad to evaluate twelve varieties of sweet orange (Citrus sinensis Osbeck). Campbel Valencia produced maximum fruit per plant (300) yielding 62.00 kg per plant with average fruit weight 206.67 g. Fruit of Casa Grande were the heaviest in weight (226.67 g) while the smallest and lightest fruits were produced by Ruby Red (155.00 g). Because of red flesh and sweetness, Ruby Red and Blood Red were promising. In general, sweet orange varieties Sulstiana, Pineapple and Casa Grande seem promising for economic and juice volume could find better scope of utility in the processing industry.
