AbstractNew crop development often depends on a few essential traits such as nonshattering of seed at maturity and pollination control. In order to domesticateLimnanthes alba(meadowfoam), as a source of industrial oil, we performed genetic analysis of crosses betweenL. albaand its closest relativeLimnanthes gracilisvar.graciliswhich shows higher selfing ability and nutlet abscission. Differences in pubescence, nutlet abscission, and seedling pigmentation were each found to be governed primarily by a single locus; two interacting loci appeared to control capsule dehiscence. Segregation distortion was detected for pigmentation in F2and F3populations, and for pubescence in several F3families. Loci controlling pubescence, nutlet abscission, and capsule dehiscence resided in a single linkage block which assorted independently of the locus controlling pigmentation.
