Abstract:

Previously generated genetically modified 22 (J2-J24) cotton transgenic events expresses Bacillus thuringiensis (Bt) derived Cry1Ac protein were evaluated for their performance in the field trial during 2014-15. Event J8 (2.23 µg/g) showed the highest accumulation of Cry1Ac protein. The maximum cumulative larval mortality reached up to 76.16 per cent in Bt Jayadhar J2 event, compared to the negative control which stood at absolute zero as expected. The Bt Jayadhar events were further evaluated for the yield parameters, fibre quality and to confirm presence of cry1Ac gene providing resistance against H. armigera.


Keywords: Cotton, Transgenic, Cry1 Ac protein, Insect bioassay.
