Milestone: One to two Bt-transgenic events of pigeonpea used for introgression into locally adapted genotypes
(KKS/HCS/KML) 2010
Milestone: Commercialization package for the introduction of pigeonpea with transgenic resistance to Helicoverpa
armigera available for deployment (KKS/HCS/KML) 2011
Milestone: Biosafety of transgene products/transgenic events to non-target organisms investigated (HCS/KKS) 2010
Movement of Bt toxins through different trophic levels in the field: We monitored the movement of Bt toxin,
Cry1Ac through different trophic levels in the field. A total of 40 insect specimens (25 from transgenic and 15 from
non-transgenic cotton) were collected, and tested for the presence of Bt-toxin using qualitative ELISA at different
intervals during the crop-growing season. Of the 25 insect species colleted from transgenic plots, 7 showed high
levels, 9 showed low levels, and the remaining 9 had no Bt-toxin. Further studies on the sensitivity of different
insect species to Bt-toxins and their uptake by the natural enemies are in progress.
