Abstract:

The insecticidal chimeric cry2AX1 gene was introduced into rice indica cultivar ASD16 with a view to impart resistance to a major lepidopteran pest, rice leaf folder. A total of 17 putative transgenic events were generated with two different constructs harbouringcry2AX1 gene and all of them were found to be positive for cry2AX1and hptII genes. The Cry2AX1 protein expression in T0transgenic rice events ranged from 0.021 to 0.093 μg/g of fresh leaf tissue. The detached leaf bit bioassay on selected transgenic plants against neonates of Cnaphalocrocis medinalis showed that the larval mortality ranged from 23.33 to 66.67 per cent in T0 transgenic plants.
