Lamont (86Ab1616)
Hulless spring oat, released by Idaho AES, USDA-ARS in 1998. The variety is relatively
tall and has strong straw, heading date is 3 days later than Monida, test weight is good,
appears equally well adapted to both irrigated and dryland production. The hulless trait
is expressed well in southern Idaho.
Ajay
A short-statured, midseason maturing variety released by Idaho AES, USDA-ARS in 1989. Ajay
is well adapted to irrigated production in southern Idaho. Ajay combines short straw and
very good lodging resistance with shattering resistance, satisfactory yield, test weight,
groat percentage and maturity. Kernel appearance is not as attractive as Monida and Otana.
Border
A short, white-kerneled variety released by the Wyoming AES, USDA-ARS in 1982. Border is a
high-yielding, relatively short-strawed variety with good lodging resistance. Border has
excellent yields under irrigation in Wyoming. Border has low protein and a fair test
weight. Border is moderately susceptible to gray speck based on Bonners Ferry data for
1977. It is susceptible to stem rust and moderately susceptible to barley yellow dwarf.
virus.
Calibre
A relativley tall, high-yielding, midseason variety released by the University of
Saskatchewan in 1983. Calibre has good test weight and groat content. It is similar to
Otana in height. Data for one year, 1984, at Bonners Ferry, indicate that Calibre is
moderately resistant to gray speck. It is resistant to Victorian blight and susceptible to
barley yellow dwarf virus, stem/crown rust, and loose smut.
Cayuse
An awned, light yellow-kerneled, stiff-strawed variety released jointly by Washington and
Idaho AES, USDA-ARS in 1966. Cayuse has an average test weight with an excellent yield
record in irrigated trials in the northwestern states and also yields well in dryland
areas. It has good lodging resistance with tolerance to barley yellow dwarf virus. It is
susceptible to gray speck in northern Idaho. Cayuse is adapted over a wide area.
Monida
A relatively tall, midseason variety released by Idaho, Montana, Oregon, and Washington
AES, USDA-ARS in 1985. Monida has moderate straw strength and good lodging resistance.
Monida has a good yield record in experimental trials in Idaho and other western states.
It is taller than Cayuse but shorter than Otana. It has good test weight, intermediate
between high test weight Otana and medium test weight Cayuse. Its kernels are similar to
Otana. Monida is similar to Otana but superior to Cayuse in groat content. Monida is
susceptible to crown rust and prevalent races of stem rust.
Otana
A relatively tall, midseason variety released by Montana AES, ARS-USDA in 1976. Otana has
moderately stiff straw and plump, short, white kernels. Otana has produced high test
weight grain in both irrigated and dryland trials. Although Otana has a relatively good
yield record under irrigation, it is too tall for production under irrigation in most
environments. Otana is resistant to Victoria blight and susceptible to shattering, stem
rust,and yellow dwarf.
Powell
Spring oat released by Idaho AES, USDA-ARS in 1998. Powell is adapted to both irrigated
and dryland production areas. Powell has higher yield than Ajay and Cayuse and is similar
to Monida. Test weight is similar to Ajay and slightly lower than Monida. Height is taller
than Ajay but shorter than most other adapted varieties. Heading date is similar to
Monida. Straw strength and shattering resistance are both very good.
Provena
A hulless variety released by Idaho AES, USDA-ARS in 1998. It averages 7 inches shorter
than Monida and 86Ab1616. Yields are not quite as high as 86Ab1616, but test weights are
higher and straw is stronger. Heading date is 2 days earlier than 86Ab1616 and 1 day later
than Monida, with good shatter resistance. Provena is relatively better under irrigation
than under dryland production.
Rio Grande
A yellow-kerneled, medium height variety released by Idaho and Colorado AES, USDA-ARS in
1990. Rio Grande is an early maturing variety with good straw strength. It has very
acceptable grain color for horse oats but has poor millling characteristics.
Saia
An Avena strigosa oat with nematicidal properties identified by Dr. Russ Ingham at OSU.
