A study was undertaken on phenotypic characterization of different isolates of Bipolaris sorokiniana isolated from the different varietal trials and nurseries of barley at the agricultural research farm, Institute of Agricultural sciences, Banaras Hindu University. The isolation was performed by transfer of single spore of the pathogen from diseased leaf in Potato Dextrose Agar media (PDA) under aseptic condition. The experiment revealed five groups of isolates on the basis of colony colour, morphology and number of spores. It was found that (42.2%) of the isolates were black in colour with profuse sporulation and suppressed type growth, (35.71%) of the isolates were greyish in colour and (21.42%) of the isolates possessed whitish colony with full plate growth and lower sporulation. The size of conidia ranged from 24 × 13µm to 36 × 14µm in size, while the number of spores per mm2 of colony varied from 20.36 to 162.77.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
