Interpretive Summary: Maverick spring oat was jointly released by the USDA-ARS; the Idaho AES, the Montana AES, and the Colorado AES in 2007. Maverick derives from the cross 80Ab988/Monida made in 1984 at Aberdeen, Idaho. The name Maverick was chosen as a term associated with ranch life. Maverick is a midseason, short spring oat with excellent yield potential under both irrigated and dryland conditions in Colorado, Idaho and Montana. Maverick has a good grain yield record in Idaho and other locations in the West. In 106 location years of testing, Maverick equaled or exceeded the grain yield of the best cultivars in the trials. Maverick also showed good forage production, equaling the best cultivars in 4 years of testing in Colorado. Maverick is similar in appearance to Monida and Otana for plant type and color but is much shorter. It is earlier than Monida but later than Otana. Kernels of Maverick are typically short to mid-long, plump and white to light cream in color. Maverick is equal in seed size to Monida and Otana with a slightly smaller groat percentage. It had a higher percent protein than Monida but lower than Otana. It was slightly lower in '-glucan than both, and between the two in percent oil. Maverick is a white hulled, high protein type favored in the equine industry.
Technical Abstract: Maverick spring oat (Avena sativa L.) was developed cooperatively by the U.S. Department of Agriculture, Agricultural Research Service (USDA-ARS), and the Idaho Agricultural Experiment Station (AES). It was jointly released by the USDA-ARS; the Idaho AES, the Montana AES, and the Colorado AES in 2007. Maverick derives from the cross 80Ab988/Monida made in 1984 at Aberdeen, Idaho. Maverick was developed utilizing a modified bulk selection program and selected as an F5:6 head row at Aberdeen, Idaho in 1990, and was given the selection designation of 90Ab1322. Maverick is a short-strawed oat cultivar suited to irrigated and higher moisture areas in Colorado, Idaho and Montana, and is a white hulled, high protein type favored in the equine industry.
