Genetic homogeneity of a recently introduced pathogen of chickpea, Ascochyta rabiei, to Australia
The study examined the genetic structure and potential for adaption to host genotype of Ascochyta rabiei, a major necrotrophic fungal pathogen of chickpea. For this, A. rabiei populations derived from six major chickpea growing regions in Australia were characterized using 20 polymorphic microsatellite markers. The overall gene (H = 0.094) and genotypic (D = 0.80) diversities among the entire population were low, indicating the establishment of a recent founder population. Since, no significant...[Show more]
