The effectiveness of mannose (using phosphomannose isomerase [
pmi
] gene) as a positive selection agent to preferably allow the growth of transformed oil palm embryogenic calli was successfully evaluated. Using the above selection agent in combination with the previously optimized physical and biological parameters and the best constitutive promoter, oil palm embryogenic calli were transformed with
pmi
gene for producing transgenic plants. Bombarded embryogenic calli were exposed to embryogenic calli medium containing 30:0 g/L mannose to sucrose 3 weeks postbombardment. Selectively, proliferating embryogenic calli started to emerge around 6 months on the above selection medium. The proliferated embryogenic calli were individually isolated once they reached a specific size and regenerated to produce complete plantlets. The complete regenerated plantlets were evaluated for the presence of transgenes by
PCR
and Southern analyses.
