Hordeum vulgare
Lacey Barley Seed


"‘Lacey’ a six-rowed spring barley (Hordeum vulgare L.) (Reg. no. CV-290, PI 613603), was developed by the Minnesota Agricultural Experiment Station and released in February 2000. It was developed in a program to obtain low soluble protein in a Midwest malting barley.

Lacey's malting quality traits, determined in collaboration with the USDA Cereal Crops Research Unit at Madison, WI, and industry testing in cooperation with the American Malting Barley Association, appear to be similar to Robust, the industry six-rowed quality standard. The following quality comparisons are based on data from 13 separate evaluations made from 1996 to 1999. For the malting quality trait of most interest, soluble protein, the values were 5.6, 5.6, and 6.7%, respectively, for Lacey, Robust, and Stander. Diastatic power is similar to Robust, but Lacey is 18% higher in alpha-amylase and yields 0.5% more malt extract. Lacey is currently being evaluated for both malting and brewing quality in industry tests coordinated by the American Malting Barley Association.

Lacey was 16% higher yielding than Robust and 3% higher than Stander in Minnesota (1996–1999). In Midwestern regional trials (1998–1999), Lacey was 12 and 4% higher yielding than Robust and Stander, respectively. Percentage plump kernels of Lacey is similar to Robust and Stander. In seven Minnesota trials where lodging occurred, the respective lodging percentages were 33% for Lacey and 42% for Robust. It is not as resistant to lodging as Stander."
