Abstract
Studies on the biophysical and biochemical basis of resistance to chickpea pod borer, Helicoverpa armigera (Hubner) was assessed under field condition at RARS campus, Vijayapur, Karnataka during rabi, 2015-16. Results revealed that at BGD 111-01 chickpea genotype showed resistance to the pod borer and recorded lower egg load on the crop (5.00 / mt row length) lower larval incidence (2.00 / mt row length) at reproductive stage and lower pod damage at harvest (6.60%) compared to Bidar bold genotype. Further, BGD 111-01 genotype had registered higher number trichome density on leaf surface, higher amount of phenol and lower amount of total sugar, reducing sugar, protein compared to Susceptible genotype (Bidar bold). Correlation study also indicated that negative correlation was found between per cent pod borer infestation with phenol content and was positively correlated with total sugar, reducing sugar, protein and total chlorophyll content.
