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
(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 (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 (326.94 kg/ha) minimum pod
damage (33.26%) and PSR (3) was recorded on GNG 1581 while, in HK-2 minimum yield (136.94 kg/ha),maximum
pod damage (83.30%) and PSR (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 (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.
