Expert Answer:

Hybridisation is the act of mixing different species or varieties of animals or plants and thus to produce hybrids
Genetic engineering on the other hand is the technology of preparing recombinant DNA in vitro by cutting up DNA molecules and splicing together fragments from more than one organism.
In a sense genetic engineering and hybridization both accomplish the same thing - they both result in new genetic types. The difference is in how they acccomplish this. Hybrids come from seeds that are developed by cross-pollinating specific parental types so that the next generation will be a very uniform crop with hybrid vigor. The hybrid gets half of its genes from each parent.
Genetic engineering usually refers to biotechnological methods that can be used to insert a very small piece of genetic material (DNA) so that the resulting plants can be nearly identical to the parent, except for the gene or genes that were inserted. Nowadays, some hybrids may have genes that are artificially inserted, using high tech biotechnology methods.   But, generally speaking, hybrids are not genetically engineered, that is , not using high-tech or biotechnology.
