Registration of three winter malting barley lines

Germplasm lines are the most important genetic resources for cultivar development. ARS669W (Reg. no. GP-216, PI 699131), ARS671W (Reg. no. GP-215, PI 699130), and ARS431W (Reg. no. GP-214, PI 699129) are three high yield and good malting quality two-rowed winter type malting barley (Hordeum vulgare L.) germplasm lines developed by the USDA-ARS breeding program at Aberdeen, ID. All three germplasm lines have been evaluated in 23 trials. Compared with the checks, all three lines have about the same or higher yield potentials. The lodging resistance of ARS669W and ARS671W is similar to the checks but better than ARS431W. The test weight of three lines was like the 'Endeavor' cultivar and higher than the 'Charles' cultivar. The winter survival rates are all the same statistically. Malting evaluation results showed acceptable quality profiles with specific quality traits including high malt extract, low protein content, and low beta-glucan for the years tested. These lines are good winter malting barley genetic stocks for future breeding or for further evaluation as possible cultivars.
