In plants, hybridization mostly generates speciation events, [5] and commonly produces polyploid species. Factors like polyploidy events also plays significant factors for understanding the hybridization events (Example: an F1 hybrid of Jatropha curcas x Ricinus communis ), [ 6 ] because these polyploids tend to have an advantage for the early ...

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.
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.
Introgressive hybridization, also known as introgression, is the flow of genetic material between divergent lineages via repeated backcrossing. In plants, this backcrossing occurs when an F 1 {\displaystyle F_{1}} generation hybrid breeds with one or both of its parental species.
Alternatives to hybridization include open pollination and clonal propagation. [2] An important factor is the heterosis that results from the genetic differences between the parents, which can produce higher yield and faster growth rate. Crossing any particular pair of inbred strains may or may not result in superior offspring.

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.
