Abstract
The development of genetic manipulation techniques has become an important tool for conventional crop breeding programs, especially where the required genes for breeding are limited. The commercialization and worldwide use of transgenic plants has been expanding since their approval for liberation in 1994, showing several benefits for the farmers as well as for the environment. This paper presents the general context of crop genetic manipulation, an example of developments in Colombia in genetic transformation of Passiflora edulis for virus resistance, and finally it refers to Biosafety issues.
