	<span lang=\"EN-US\"><span style=\"font-family:Verdana;\">Genotypic and
phenotypic variation among 16 isolates of </span><i><span style=\"font-family:Verdana;\">Ramularia
areola</span></i><span style=\"font-family:Verdana;\"> of </span><i><span style=\"font-family:Verdana;\">Gossypium hirsutum</span></i><span style=\"font-family:Verdana;\"> collected from five different geographical regions of Brazil was studied
through virulence spectrum on three cultivars in the glasshouse and through
ERIC- and REP-PCR and ITS1-5.8S-ITS2 rDNA analysis. Difference in virulence
spectrum and molecular analysis of some isolates was observed. ERIC- and
REP-PCR showed similar results and revealed a high level of diversity among the
isolates. A unique profile for both ERIC and REP was obtained for most
isolates. On the other hand, the ITS rDNA analysis did not show different
PCR-RFLP patterns. While some isolates differed among each other considering
genotypic and phenotypic reactions, no clear cut evidence was found about the
existence of genetic lineages of </span><i><span style=\"font-family:Verdana;\">R.

Identification of genetic variability among the </span><i><span style=\"font-family:Verdana;\">R. areola</span></i><span style=\"font-family:Verdana;\"> isolates originated from different geographic regions
would permit screening of Brazilian germplasm and achieve sources with a wide
spectrum of resistance. This is the first report of the genotypic and
phenotypic variability among the </span><i><span style=\"font-family:Verdana;\">R.
