Abstract
On the basis of incidence of appearance of Ascochyta blight symptoms after artificial inoculation of 25-day-old chickpea seedlings with 10 different pathotypes of Ascochyta rabiei, GL94011, PBG5 and C214 have been classified as resistant, moderately resistant and susceptible, respectively, to Ascochyta blight. In none of the pathotypes, peroxidase (PO) activity could be detected in culture medium and mycelium. Healthy tissues of GL94011 have almost three times the PO activity in comparison with that of C214. Resistant and moderately resistant genotypes showed 30–60% upregulation of PO activity against infection by A. rabiei whereas it was only 3–6% in susceptible genotype C214. These results indicate the possibility of using PO as a marker of Ascochyta blight resistance
