Abstract
Artificial inoculation with a spore suspension of Ascochyta rabiei showed highest leaf and branch infection in Aug424 followed by Pb-1 with maximum resistance in ILCI91 followed by CM72. Histological studies showed that thickness of stem epidermis was significantly higher in ILCI91. Thickness of stem hypodermis was also greater in ILCI91 and CM72 as compared to Pb-1 and Aug424 , with minimum thickness of cortical region in Aug 424. The fungus caused severe damage to different tissues of Aug424 and Pb-1 soon after infection as compared to CM72 and ILCI91.
