s. One obstacle to use is the oil's reddish-brown color, which makes it less valuable for certain applications than the colorless or pale yellow castor oil. Breeding may reduce the pigment load of the lesquerella's oils over time. Breeding may also favor other characteristics in lesquerella, such as its capacity for cultivation in other climates, male sterility to allow better control of pollination
