Lathyrus × Hammettii
''Lathyrus × hammettii'' is a hybrid Hybrid may refer to: Science * Hybrid (biology), an offspring resulting from cross-breeding ** Hybrid grape, grape varieties produced by cross-breeding two ''Vitis'' species ** Hybridity, the property of a hybrid plant which is a union of two diff ... flowering plant within the genus ''Lathyrus'' and family Fabaceae''.'' The hybrid was produced by artificially hybridizing Sweet pea, ''L. odoratus'' with ''Lathyrus belinensis, L. belinensis''. History The hybridization of these two species was first attempted by plant breeder Dr Keith Hammett, using the sweet pea cultivar ''Lathyrus odoratus'' 'Orange Dragon', ''L. belinensis'' and embryo rescue techniques. The hybrid was attempted in hopes of producing a yellow sweet pea, which plant breeders have been attempting to create for decades. The F1 hybrid offspring produced from the cross were self sterile and possessed pink flowers. Multiple non yellow cultivars of ''Lathyrus × hammettii'' ha ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...
