Hybridisation in plants refers to the process when two plants which are not genetically similar and have difference in their traits due to different genetic patterns are crossed or allowed to reproduce.

Hybridisation crosses can be between two different species i.e. interspecific, between two different varieties i.e. intervarietal and it can be between two different genera i.e. intergeneric according to the requirement of the desired traits.

Following are the two desired characters for which it is done:

•Resistance to different diseases is the most desirable trait as it provides ability to the plant to be disease free.

•High yield is another desirable trait as the main purpose is fulfilled here. If some variety or species have high yields it will provide benefit to us and therefore is one of the desired traits.
