Technical Abstract: 'Jay' spring oat (Avena sativa L.) was developed cooperatively by the Purdue University Agricultural Research Programs and the USDA-ARS and was released in 1998. Jay has resistance to crown rust, caused by Puccinia coronata Corda var. avenae W. P. Fraser & Lidingham, barley yellow dwarf virus BYDV), and loose smut, caused by Ustilago avenae (Pers.) Rostr. Jay was developed using a modified pedigree method of breeding. Jay is adapted throughout the North Central region and is particularly well suited to the upper Midwest region because of its resistance to crown rust and BYDV. Jay has high yield potential, producing 4,788 kg ha-1, compared with 4,191 kg ha-1 for Ogle, averaged over 6 yr at Lafayette, IN. Jay has excellent test weight, ranking in the upper 10-15 percent of entries in regional trials. Jay ranked in the best 10 percent in regional trials for short plant height (81 cm), lodging (13%), and groat protein yield (442 kg ha-1). BYDV symptom severity's (0=no symptoms; 9=severe leaf discoloration and plant stunting) on Jay, Classic, INO9201 and Ogle in controlled tests at Lafayette averaged over six years were 3.5, 3.0, 4.1, and 4.5, respectively. Breeder seed produced in 1997 was the F14 generation, which was grown in 1998 to produce foundation seed. The generation sequence of seed production is foundation, registered, and certified. Protection of Jay under the U. S. Plant Variety Protection Act has been applied for. Breeder seed of Jay is maintained by the Purdue University Agricultural Research Programs, West Lafayette, IN
