Abstract :A field experiment was conducted to screen the 15 chickpea genotypes against gram pod borer by using biochemical parameters at Research Farm of Pulses Section, Deptt. of G&PB, CCS Haryana Agricultural University, Hisar, Haryana insert ignore into journalissuearticles values(India);. The pooled analysis of two winter season 2013-14 & 2014-15 revealed thatthe maximum and minimum mean larval population of Helicoverpa armigera was 17.99 and 28.50 l/mrlon GNG 1581 and HK-2 genotype, respectively. The yield, per cent pod damageand pest susceptibility rating insert ignore into journalissuearticles values(PSR); ranged from 136.94 to 326.94 kg/ha, 33.26 to 83.30% and 3 to 7, respectively. Among the 15 chickpea genotypes maximum yield insert ignore into journalissuearticles values(326.94 kg/ha); minimum pod damage insert ignore into journalissuearticles values(33.26%); and PSR insert ignore into journalissuearticles values(3); was recorded on GNG 1581 while, in HK-2 minimum yield insert ignore into journalissuearticles values(136.94 kg/ha);,maximum pod damage insert ignore into journalissuearticles values(83.30%); and PSR insert ignore into journalissuearticles values(7); was observed. The content of different biochemical in chickpea plantsviz., Malic acid, Total phenol, Total soluble sugars, Cellulose, Hemicellulose and Lignin were evaluated for screening and these listed biochemicalranged from 137.51 to 265.65 mg/g, 35.62 to 60.06 mg/g, 2.28 to 4.12 mg/g, 16.05 to 27.15 mg/g, 16.30 to 22.65 mg/g and 6.80 to 12.10 mg/g, respectively. The significant and negative correlation coefficient was recorded between malic acid and mean larval population of H. armigera insert ignore into journalissuearticles values(r= -0.69**); while, all other parameters were correlated non-significantly. Thus malic can be used as selection criteria for identifying H. armigera tolerant genotypes in chickpea.
