A hundred and seventy monoconidial isolates of the pathogen virulent to ‘Primavera’ and 139 to ‘BRS Bonança’ collected from eight fields, during two years (2001-2003) were tested, under greenhouse conditions, on six newly rele...
متن کاملVirulence and rep-PCR Analysis of Pyricularia grisea Isolates from Two Brazilian Upland Rice Cultivars
The phenotypic and genetic diversity of 77 isolates of Pyricularia grisea collected from two upland rice cultivars, Maravilha and Primavera, was studied. Isolates exhibiting compatible reaction to cv.Primavera were incompatible to cv.Maravilha and vice versa, with the exception of six isolates that were compatible to both cultivars.
