abstract
Screening of chickpea germplasm for identifying the biophysical and biochemical basis of host plant resistance were carried out against Callosobruchus chinensis (L.) under laboratory condition during 2017-18. Observation recorded revealed that the germplasm ICC39735 (57.33 eggs/100 seeds) was least preferred for egg laying, while maximum number of eggs were recorded on ICC6263 (177.67 eggs/100 seeds). Maximum developmental periods (29.83 days) for pulse beetle & minimum per cent adult emergence (11.89%), growth index (0.035) were recorded on ICC372351 showing considerable resistance pulse beetle. On the basis of morphological observation, the female beetle laid the minimum number of eggs on rough and medium sized seeds of ICC397375, however maximum number of eggs were found on smooth and black colored seeds of ICC6263. The germplasm ICC372351 with maximum phenol (1.63 mg/g), flavonoid (0.42 mg/g) & Protease inhibitors (3.31 IU/g) content recorded lowest growth index for pulse beetle.
