Differentiation of populations of AG-2-2 of Rhizoctonia solani by analysis of cellular fatty acids
1993
Johnk, J.S. | Jones, R.K.
A population of Rhizoctonia solani representing AG-2-2 IIIB (mat rush type) and AG-2-2 populations isolated from corn, sugar beet, and turfgrass were analyzed for cellular fatty acid composition. The AG-2-2 IIIB population and populations of isolates from turfgrass and from sugar beet (AG-2-2 IV) were differentiated by cluster and principal component analyses of the percent composition of the fatty acids identified. A dendrogram of the four populations shows that AG-2-2 IIIB and the population from corn were closely related, and the population from turf was distinct from AG-2-2 IIIB and AG-2-2 IV.
