Crown rust (Puccinia sp.) infection in oats continues to plague oat production, especially in the southern half of Minnesota. For all 40 entries of the variety trial, yields were highest at the crookston station in 1995 followed closely by Rosemount, Grapnd Rapids and Morris. Yields were down at Waseca and especially Lamberton, because of the extreme heat in the middle of June, and also by severe lodging. Yields at Roseau were even higher than those at Crookston, but only eight named cultivars were included at Roseau.
Some of the varieties have been in the oat variety tests for only one or two years. The average yields of these varieties have been adjusted mathematically to allow valid comparisons. Two-year and especially one-year data are less reliable and should be interpreted with caution.
Three cultivars - Belle, Classic, and Whitestone-have not been included in these test in previous years. Belle is from Wisconsin and is late maturing, high yielding, with good test weight and lodging resistance. It is resistant to smut and crown rust and has some tolerance to Barley Yellow Dwarf Virus (BYDV).
Classic is from Purdue and is medium maturing and lodging resistant, good yielding and has average test weight. It is resistant to smut, has some resistance to crown rust, and good tolerance to BYDV. Whitestone is from North Dakota and is late maturing, good yielding but has average test weight. It is susceptible to lodging and smut but has some resistance to crown rust.
In 1995, Belle and Milton were decidedly higher yielding than all other cultivars in the tests. All other cultivars performed generally consistent with that of previous years.
