Evaluation and Screening of Sweet Orange Cultivars for Vegetative Growth and Citrus Canker

This study was conducted at National Agricultural Research Center, Islamabad. The experimentwas performed on randomized complete block design (RCBD) consisting of eleven treatments(cultivars) replicated three times during 2015. The results showed that Tarocco attained maximumheight (156.13 cm), followed by Mexican Lemon (146.80 cm). Similarly, maximum plant spread andleaf area were recorded in Mexican Lemon 124.07 cm and 11.35 cm^2, respectively. However, Hamlin showed the highest stem girth (9.90 cm) and number of branches (66.53). The internode length was the greatest in Kinnow cultivar (2.66 cm). In case of disease incidence maximum lesion on leaves were found in Kinnow (14.2) while in Cara Cara, Salustiana and Arnold Blood, lesser lesions were found. On the basis of results and overall performance Tarocco and Hamlin performed best in all aspects while Arnold Blood and Cara Cara revealed poor growth.
