Interpretive Summary: An obstacle for some cosmetic industry applications of Lesquerella fendleri is the dark pigmentation of the seed oil. Many applications of this hydroxy seed-oil require special processing, thereby increasing costs, to remove pigmentation from the oil. Plants were selected for a mutant seed coat color, which is associated with the seed-oil pigment. The oil from this new germplasm line has less pigmentation and provides germplasm with high genetic diversity for future improvements by public and private researchers. Development of lesquerella into a viable commercial crop will provide an alternative crop for U.S. farmers and an alternative domestic source of hydroxy fatty acids presently filled by imported castor.
