Fetch, J.W.M., Kibite, S., Chong, J., Clayton, G.W., Fetch, T.G., Menzies, J.G., Turkington, T.K. (2009). Lee Williams hulless oat, 89(4), 665-669.


Can. J. Plant Sci. 89: 665-669. Lee Williams is a high-yielding hulless oat (Avena sativa L.) with good disease resistance and good straw strength. It is well adapted to all of the oat producing regions of western Canada. It carries genetic resistance to several races of crown rust (caused by Puccinia coronata Corda f. sp. avenea Eriks.) and stem rust (caused by P. graminis f. sp. avenae Pers.), loose [Ustilago avenae (Pers.) Rostr.], and covered smut (U. kolleri Wille), and moderate resistance to barley yellow dwarf virus (BYDV). Lee Williams has protein and oil levels and a high groat to hull ratio that make it well-suited for livestock feed. Hulless oat may retain a low percentage of hulls after threshing so a high groat to hull ratio is desirable. Lee Williams was supported for registration at the Prairie Regional Recommending Committee for Grains meeting in February 2002.
