Title Development and Analysis of Transgenic
Chickpea for Resistant to
Helicoverpa armigera (Hubner)
 
Creator Mohammed Mubarak, V
 
Subject Chickpea
 
Description The production of chickpea has been reduced considerably for the past 2 to 3
decades mostly due to biotic and abiotic stress factors. On the global basis, annual yield
loss due to these factors was estimated to be 11.2 million t, wherein 4.8 million t is being
contributed by biotic factors alone (Ryan, 1997, www.icrisat.org). Amongst the biotic
factors, the notorious pod borer Hel~coverpu armigera causes a severe pod damage of up
to 90% accounting for about 10-33 % per cent yield failure, resulting in annual losses of
over US $325 million (ICRISAT, 1992; Yadav et al., 2006). Often, the extent of losses
caused by this pest has led to the total failure of the crop (Jayaraj, 1990). This serious
threat has been ascribed to frequent and fast changes occurring in cropping pattern of
agroecosystem and the polyphagous and cosmopolitan feeding nature of H. armigera
