| Abstract: | Limnanthes is a potential seed oil source of long chain fatty acids. Agronomic evaluations in Alaska, California, Maryland, and Oregon indicate that theL. alba group has the best crop potential because of superior seed retention and erect growth habit. Experimental seed yields of 1700 kg/ha or more indicate that economically feasible yields on a commercial scale will be attainable, as continued study reveals optimum cultural practices and utilizes variability present in the various accessions. For the best seed yields,Limnanthes must be handled as a winter annual in California, Maryland, and Oregon but as a spring-seeded annual in Alaska.Limnanthes plants mature rapidly during hot weather; thus the timing of harvest is critical for maximization of seed yields. Further studies on seeding rates, weed control, and harvest methods are suggested. |
