Hybridization involves pollination of two individuals of different species (or two varieties within a species). This pollination can occur randomly in nature or via intentional pollination through human involvement.
Plants or seeds labeled F1 are first filial generation hybrids. They may exhibit “hybrid vigor” with higher yields or other desirable characteristics. Seeds from F1 plants are unstable and often do not produce plants that are true-to-type. Some hybrids can be stabilized through many generations of plant selection.
