A reliable protocol for efficient shoot induction in brinjal cv. CO 2 was developed. The effects of different plant growth regulators and explant types in in-vitro shoot induction were studied. The 12-15 days old cotyledonary leaves showed the maximum shoot induction. The regeneration efficiency was significantly increased by using Thidiazuron (TDZ) in culture medium as a growth regulator. Following the standardized regeneration protocol, Agrobacterium-mediated transformation of brinjal cv. CO 2 was optimized. Cotyledonary leaf bits were used for co-cultivation with the Agrobacterium strain LBA4404 carrying pCAMBIA 2301 vector. A transformation efficiency of 33.5% was obtained by using the cotyledonary leaves as explants. The transformation efficiency was significantly enhanced when the explants were cocultivated on medium overlaid with Whatman No.1 filter paper.
