Hybridization sometimes results in introgression, which can occur in response to habitat disturbance that puts plant species into contact with each other. [2] Introgression is gene transfer among taxa and is a result of hybridization, followed by repeated backcrossing with parental individuals.

In 1994, a hybrid was made between longan (Dimocarpus longana) and lychee (Litchi chinensis) [22] A list of plants that can hybridize under the same genus (Interspecific introgression, allopolyploid origin, and interspecific hybrid origin) can be found here: List of plant hybrids
Hybridization is a particularly common mechanism for speciation in plants, and is now known to be fundamental to the evolutionary history of plants. [4] Plants frequently form polyploids, individuals with more than two copies of each chromosome. Whole genome doubling has occurred repeatedly in plant evolution.

Interspecific incompatibility in plants can occur for many reasons, but most often embryo abortion occurs [3] In plant breeding, wide hybridization crosses can result in small shrunken seeds which indicate that fertilization has occurred, however the seed fails to develop. Many times, remote hybridizations will fail to undergo normal sexual ...
A form of hybrid speciation that is relatively common in plants occurs when an infertile hybrid becomes fertile after doubling of the chromosome number. Hybridization without change in chromosome number is called homoploid hybrid speciation. [1] This is the situation found in most animal hybrids.
Fused protoplast (left) with chloroplasts (from a leaf cell) and coloured vacuole (from a petal) Somatic fusion, also called protoplast fusion, is a type of genetic modification in plants by which two distinct species of plants are fused together to form a new hybrid plant with the characteristics of both, a somatic hybrid.
