Isolation and characterization of fungi from sugar beet roots samples collected from Morocco

The aim of this study is to isolate and characterize fungal communities from moroccan sugar beet. isolation of fungi was performed using standard microbiological techniques. fifty-five fungal isolates belonging to eight different genera were recovered: alternaria,fusarium,pythium,rhizopus,botrytis,aspergillus,rhizoctonia,penicillium. of 55 isolates obtained,43 were identified to species level. the fungi species associated with moroccan sugar beet root were fusarium oxysporum,pythium sp.,alternaria alternata,botrytis cinerea,aspergillus niger,rhizoctonia solani,rhizopus stolonifera and penicillium expansum. isolates belonging to the genera fusarium (18 isolates),pythium (12 isolates) and alternaria (9 isolates) were dominant. the obtained species could be classified into three groups: (a) well-known and economically important pathogens of beet,(b) commonly abundant phyllosphere those considered as primary saprobes and minor pathogens and (c) species that are occasionally present in beet. © 2017,university of mohammed premier oujda morocco.
