Effect of Different Inoculum Levels of Ascochyta lentis on Growth and Yield Attributes of Lentil Plant

Effect of different inoculums levels (10 3 , 5x10 3 , 10 4 , 5x10 4 spores/ml) of A. lentis was studied on growth and yield parameters of four lines of lentil. Results showed that among these lines one (ILL-358) showed microsperma resistant, one (ILL-4605) macrosperma resistant, one (ILL-5580) microsperma susceptible and the remaining one (ILL-6002) macrosperma susceptible response over control. Plant height was the minimum in case of all the four lentil lines are at 5spores/ml. Similarly no. of leaflets, no. of pods/ plant, no. of grains/pod and 100 grain weight were reduced with increased level of spores concentration from 10 3 spore/ml to 5x10 4 spore/ml. Size and frequency of lesions/pods showed positive correlation with increasing spore concentrations.
