Abstract:
Many commercial cultivars of mango are highly susceptible to bacterial leaf spot and infections can result in drastic yield losses. Symptomatic and morpho-cultural variability studied among different isolates of Xanthomonas campestris pv. Mangiferaeindicae causing mango bacterial leaf spot. Diseased samples collected from marathwada region expressed a wide range of variability in respect of lesion shape, size and colour etc. Cultural and morphological characters of different Xanthomonas campetris pv. Mangiferaeindicae isolates were studied on nutrient agar media. Eight isolates collected from different locations of Marathwada region differed in respect of cultural characteristics viz., pigmentation, colony shape, elevation, margin, surface appearance and cell shape were studied using NA as basal culture medium. Among the eight isolates tested, six isolates viz., Xcm1, Xcm3, Xcm4, Xcm6, Xcm7 and Xcm8 exhibited cream to white pigmentation while rest two (Xcm2 and Xcm5), exhibited white to pale yellow pigmentation. All the isolates had filiform colony shape, convex elevation and entire colony margin. However, all the isolates were morphologically single rods.
