Abstract
The comparative assessment of density of glandular hairs, population and size of stomatal aperture in chickpea cultivars resistant (R), moderately resistant (MR), moderately susceptible (MS) and susceptible (S) to Ascochyta blight revealed that the density of the glandular hairs on the ventral, dorsoventral sides and population and size of the aperture of stomata were highly significantly different among the four reaction groups. Similarly length of the glandular hairs and area of stomata were significantly different among the four reaction groups. In the resistant reaction group of cultivars, there were higher number of glandular hairs on the ventral, dorsoventral sides and higher number of stomata of leaf as compared to susceptible group. There was no appreciable difference among the population of glandular hairs on ventral side, length of non-glandular hairs and size of stomata of two reaction groups of resistant and susceptible cultivars. The resistant group had the smallest aperture than other groups.
