Abstract : Anthracnose of mango (Mangifera indica L.), caused by Colletotrichum gloeosporioides (Penz.) Penz. and Sacc. is one of the most serious diseases of mango worldwide. Morphological variations in relation to conidial size in the isolates of Colletotrichum gloeosporioides were studied. Variation among the six isolates of C. gloeosporioides of mango (BDR, BLR, DWR, KLR-1, KLR-2 and RCR) was studied on the basis of symptoms pattern on eight mango cultivars by detached leaf technique. The average conidia measured 10.9-20.6 µm length and 4.39 to 6.65 µm width. The isolates showed differential reaction on mango cultivars. RCR and BDR isolates showed more virulent on cv Khader, Mulgoa, AURumani and Beneshan. BLR and BDR isolates were more virulent on Alampur Beneshan, while RCR, KLR-1 and BLR isolates were more virulent on Beneshan. Further, BLR and RCR isolates showed more virulent on Mallika and RCR, KLR-2, BLR and DWR isolates showed more virulent on Mulgoa.
