Lathyrus × hammettii is a hybrid flowering plant within the genus Lathyrus and family Fabaceae. The hybrid was produced by artificially hybridizing L. odoratus with L. belinensis.[1]
History
[edit]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.[2] The hybrid was attempted in hopes of producing a yellow sweet pea, which plant breeders have been attempting to create for decades.[3][4] The F1 hybrid offspring produced from the cross were self sterile and possessed pink flowers.[3] Multiple non yellow cultivars of Lathyrus × hammettii have been produced descending from those plants.[3]
Mildew resistance
[edit]Lathyrus belinensis possesses genetics that exhibit mildew resistance.[5] L. odoratus is susceptible to mildew.[6] Hybrids produced between the two species were found to be resistant to the fungus Erysiphe pisi, which causes mildew in sweet peas.[7]
