The seedling choice is a critical factor for the establish-
ment of new citrus groves and can guarantee the grove’s
health and productivity. Of the various seedling supply
sources, micropropagation methods have gained much at-
tention recently due to their ability in producing healthy,
uniform, true to type and authentic seedlings (George et al.
2008). Likewise, parallel to conventional breeding methods,
genetic transformation has been shown to be a powerful
strategy for cultivar improvement while maintaining its in-
tegrity by adding a single new trait (khan et al. 2009).
