Varietal response of chickpea against the gram pod borer, Helicoverpa armigera (Hubner) under natural field conditions
K Dinesh, R Bharu Singh and S Anusha
Comparison of susceptibility response among ten chickpea varieties against gram pod borer showed that none was completely resistant against this pest. Variety Vijay recorded lowest (19.73 and 23.33%) pod damage followed by RSG 888 (20.46 and 27.67%); whereas, Samrat recorded pod damage of (30.40 and 34.33%) per cent followed by Kabuli with highest (31.26 and 37.04%) pod damage. Percent pod damage was recorded from varieties GNG 1581, Dahod Yellow, BGM 564, RSG 963, BGM 564 and local gram ranged between (23.66 to 28.26%) and (28.67 to 33.33%).However varieties Vijay and RSG 888 were found to be lest susceptibility while GNG 1581, Dahod Yellow, Samrat, BGM 547, RSG 963, RSG 564 and Kabuli were moderate susceptibility. The maximum yield was recorded for Vijay (2.12 and 2.02 kg/plot) followed by RSG 888 (1.90 and 1.80 kg/plot). The minimum yield was recorded for Samrat (1.45 and 1.41 kg/plot) and Kabuli (1.18 and 1.08 kg/plot), respectively during 2013-14 and 2014-1.
