Protandry in meadowfoam Limnanthes alba Benth. is believed to hinder seed yield through the interaction of honey bees (Apis mellifera L.), as essential pollinators, with environmental variables. The objective of this research was to develop a self-pollinating meadowfoam having an L. alba plant type. Interspecific hybridization of L. alba with the autogamous L. floccosa Howell was used. Three subspecies of L. floccosa (pumila, bellingeriana, and grandiflora) were crossed with 10 selections of two subspecies of L. alba (alba and versicolor) during a 3-year period. Only the L. floccosa ssp. grandiflora ✕ L. alba ssp. alba produced viable, fertile, self-pollinating F1 hybrid plants. Selections for plant type, autogamy, and high seed yield were made in the F2, F3, and F4 generations. The results of this research show that it is possible to develop a self-pollinating meadowfoam cultivar with an L. alba plant type.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
