abstract
Seven interspecific chickpea genotypes along with ICCL 86111 and L 550 as resistant and susceptible checks were evaluated against Helicoverpa armigera under laboratory conditions during rabi 2014-15 and 2015-16. Pooled data revealed that the larval and pupal duration varied from 21.68 to 23.49 and 14.09 to 15.89 days in all the test genotypes. Genotype GLW 32 (23.49 days) had recorded longest larval duration and was at par with GLW 8, GLW 48 and GLW 84. Resistant and susceptible checks had recorded larval duration of 20.86 and 20.62 days and were at par with GLW 131 (21.68 days). Similar trend was followed for pupal duration. The larval and pupal survival was ranged from 61.27 to 85.99 per cent and 62.50 to 88.25 per cent, respectively. Genotype GLW 32 had recorded lowest larval survival (61.27%) and was at par with GLW 8. Susceptible check L 550 had recorded highest larval survival of 93.33 per cent. Similar trend was followed for pupal survival. Significantly lowest adult longevity of 11.17 days was also recorded in GLW 32, which was at par with GLW 8.
