  abstract = {{I}n recent years, {B}rown spot disease of rice ({BSR}) has been observed on leaves and seeds of rice in all rice-growing areas of {B}urkina {F}aso. {B}ipolaris oryzae and {E}xserohilum rostratum are the main fungal species isolated from {BSR} infected tissues and they are frequently observed in the same field. {H}owever, we are lacking information on the genetic diversity and population structure of these fungi in {B}urkina {F}aso. {T}he mode of reproduction is also unknown. {T}he genetic diversity of isolates of {B}. oryzae (n=61) and {E}. rostratum (n=151), collected from major rice-growing areas of {B}urkina {F}aso, was estimated using genotyping-by-sequencing ({GBS}). {T}he mean values for nucleotide diversity (?) were 1.9 x10-4 for {B}. oryzae and 4.8 x10-4 for {E}. rostratum. {T}here is no genetic differentiation between the geographical populations of each species. {T}he analysis of molecular variance revealed that 89% and 94% of the genetic variances were within the populations of {B}. oryzae and {E}. rostratum, respectively. {F}or each species, four genetic clusters were identified by two clustering methods ({DAPC} and s{NMF}). {T}he distribution of these genetic groups was independent of the geographical origin of the isolates. {E}vidence of recombination was detected in the populations of {B}. oryzae and {E}. rostratum. {F}or {B}. oryzae balanced mating type ratios were supporting sexual reproduction. {F}or {E}. rostratum overrepresentation of {MAT}1-2 isolates (79%) suggested a predominant asexual reproduction. {T}his study provides important information on the biology and genetics of the two major fungi causing brown spot disease of rice in {B}urkina {F}aso.},
