Technical Abstract: Ascochyta blight caused by Ascochyta rabiei is an important disease of chickpea. The pathogen is known to produce several phytotoxins. Reciprocal grafting between resistant and susceptible chickpea genotypes was employed to elucidate possible mechanisms of resistance by detecting translocations of disease-mediating agents such as toxin receptors or detoxifying enzymes across the graft junction. Chickpea genotypes Dwelley and Spanish White were grafted reciprocally and self-graft, and inoculated with isolates of either pathotype I or pathotype II of A. rabiei. Results showed that the scions of a given genotype grafted onto either resistant or susceptible genotype rootstocks reacted similarly to infection by A. rabiei. The genotype of the rootstock showed no detectable effect on the disease phenotype of the scion. The disease phenotype is conditioned locally by the scion genotype.
