A hulless spring oat developed by the Cereal Research Centre (formerly Winnipeg Research Centre) in Winnipeg, Manitoba. It bears the accession number W87186 and OT258 and was tested in the Western Oat Co-op Test from 1989 to 1991. AC Belmont was licensed by the Food Production and Inspection Branch in 1992.

AC Belmont originated from the cross 83HN3693/W82281//OT232.

Based on disease resistance data, kernel quality data, yield and other agronomic data, AC Belmont appears to be well suited for planting in the oat growing areas of western Canada.

Like the well adapted oat variety "Dumont", AC Belmont is resistant to stem rust, and to loose and covered smut. Like Dumont, AC Belmont is also resistant to the races of rust that are avirluent on the Pc38 and 39 crown rust resistance gene combination but susceptible to the new races of crown rust that are virulent to this gene combination. Its tolerance to barley yellow dwarf virus (BYDV) is similar to that of Dumont but greater than that of Terra.

The test weight, kernel weight and kernel protein content of AC Belmont is slightly less than that of Terra. The percent plump, percent hulless kernels (versus covered kernels in a sample), groat colour and oil content of AC Belmont and Terra are similar.

AC Belmont yields approximately 10% more than Terra based on 47 station-years of testing in western Canada. Based on the groat yields of Dumont, Calibre and Cascade, AC Belmont also yields more than these common oat checks. AC Belmont has lodging resistance similar to Terra and Cascade and better than Dumont and Calibre. AC Belmont matures in the same number of days as Dumont and Calibre; but is 1.5-3 days later than Terra and Cascade. AC Belmont and the check cultivars are all of a similar height class; AC Belmont is 2-4 cm shorter than Terra and Dumont and 7-10 cm shorter than Calibre and Cascade.

AC Belmont is a hulless oat with its major strengths being good yield potential and resistance to stem rust, the smuts and to some races of crown rust. Its susceptibility to the new races of crown rust is its primary weakness.
