Description This research was conducted to study the inheritance of virulence, mating
type distribution, pathogen diversity for Ascochyta rabiei affecting chickpea, and to
screen sub set chickpea accessions against the highly virulent pathotype IV.
Inheritance of virulence was studied by doing crosses between pathotypes three
crosses were made and 20 progenies per cross were tested on susceptible and
resistant chickpea genotypes, chi square test showed that inheritance of virulence
was controlled by single gene. Mating type distribution for 78 isolates collected from
four countries was investigated by using MAT-specific primers, and the study
showed no significant deviation from 1:1 ratio. Pathogen diversity for 96 isolates
collected from four countries was studied studied by using eight SSR primers , the
study showed highly genetic diversity between the isolates. Finally the reaction of
200 chickpea genotypes against pathotype IV the highly virulent pathotype was
studied and just one genotype showed moderately resistant reaction.
