Cultural, morphological and molecular characteristics of Fusarium oxysporum f. sp. udum were studied where eight isolates indicated a great variability amongst them. However, the isolate FOC-2 (Jalna) exhibited maximum mycelial growth of 90 mm. The isolates viz., Jalna (FOC-2) and Beed (FOC-3) produced partially submerged (FOC-2) to submerged (FOC-3) white sparse dense growth with smooth margin and bright white substrate pigmentation, respectively. | Cultural morphological and molecular variability of Fusarium oxysporum f. sp. udum Isolates by RAPD method
