The present research on the “Characterization of Cry IIa transgenic chickpea lines and their interaction with natural enemies of Helicoverpa armigera (Hubner)” was carried out under laboratory and field conditions at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Patancheru, Andhra Pradesh, India, during 2011 – 14. The transgenic plants suffered significantly lower leaf damage as compared to the non-transgenic plants. The larval survival and weight gained by H. armigera larvae after 5 days was significantly reduced on transgenic lines as compared to that on non-transgenic chickpeas during October and November plantings 2011-12 and 2012-13. The transgenic lines BS5A.2(T2) 19-1P2 and BS5A.2(T2) 19-2P1 exhibited significantly lower leaf damage rating, larval survival and mean larval weight under laboratory conditions. In glasshouse conditions, BS5A.1(T2) 18-1P1 suffered significantly lower leaf damage and mean larval weight was also reduced but the larval survival of H. armigera was significantly reduced on BS5A.2(T2) 19-2P1. Significant differences in grain yield were observed between transgenic and non-transgenic plants infested with H. armigera. BS5A.2(T2) 19-2P1 had the highest dry matter weight, pod weight, seed weight and number of seeds formed as compared to the other transgenic and non-transgenic chickpea lines under infested and un-infested conditions...
