Abstract:

Helicoverpa armigera (Hubner) is the major constraint for the production of chickpea as it feeds on the pods causing direct economic damage to the farmers. A single H. armigera larva feeds 30-40 pods in its life time. It is polyphagous and multivoltine pest which is difficult to control. Farmers generally rely on the insecticides but this pest was reported to show resistance to most of the insecticides used against it. Host plant resistance for managing this pest is best as it is compatible with other pest management practices. The chickpea plant was observed to have certain morphological characters which reduce the preference of the pod borer. In the current experiment, 18 chickpea varieties were studied for the effect of morphological characters viz., plant height, number of primary branches, number of pods per plant, 100 grain dry weight, pod trichome density, pod length and pod width on pod damage by H. armigera. It was found that the average pod density was significant and negatively correlated with the per cent pod damage during 2015-16 (r = -0.911) and 2016-17 (r = -0.619) while the other morphological parameters were non significant. The pod trichome density was highest in the variety C-235 during 2015-16 and 2016-17. Further, plant height, number of pods per plant and 100 grain dry weight were observed to be positive and non significantly correlated with per cent pod damage during two years of experiment.
