Abstract:
The objective of the present investigation was to distinguish between different Xanthomonas axonopodis pv. citri (Xac) isolates, the causative agent of canker in acid lime. 32 different isolates were gathered from acid lime canker lesions (leaves and fruits) in Andhra Pradesh's potential growing regions. In the present study, morphological characteristics and biochemical technique i.e Grams staining were used to identify different Xac isolates. All 32 isolates grown on nutrient agar media produced small, yellow to orange yellow colonies with a variety of margins, according to the morphological studies. Grams staining test were performed on these isolates and all the isolates were found negative to Grams staining test.
