DUARTE LEAL, Yanisia; ECHEVARRIA HERNANDEZ, Anayza  and  MARTINEZ COCA, Benedicto. Identification and characterization of Fusarium spp. isolates present in chickpea (Cicer arietinum L.) in Cuba. Rev. Protección Veg. [online]. 2016, vol.31, n.3, pp.173-183. ISSN 1010-2752.

The aim of this study was the cultural and morphological identification and characterization of sixteen isolates of Fusarium spp. from chickpea (Cicer arietinum L.) seeds and plants. Colony color (surface and reverse) and texture, shape of the colony edges, presence of rings on the colony surface, and the linear growth, were the cultural variables evaluated.  Size, shape, and color of the vegetative and reproductive structures were the morphological variables examined. A taxonomic key was used for identifying  the fungi. All the isolate characteristics analyzed showed a great variability. It was identified the presence of Fusarium proliferatum (Matsushima) Nirenberg, Fusarium nygamai Burgess & Trimboli, Fusarium dlamini Marasas, Nelson & Toussoun, and Fusarium phyllophilum Nirenberg & O’Donnell, all them represented by one isolate. Two isolates corresponded to Fusarium solani (Martius) Appel & Wollenweber emend. Snyder & Hansen and three to Fusarium oxysporum Schlechtendahl emend. Snyder& Hansen. According to its characteristics, one of the isolates  remained as Fusarium sp. Cultural variability was observed among the isolates of a same species, which showed the possible presence of biotypes
