Interpretive Summary: Hulless barley is considered a good source of food and feed. Hulless barley has higher feed value and is more nutritious than hulled barley. Because it has no hulls, hulless barley tends to yield 15 to 20% less per acre than control hulled varieties. Development of hulless barley with increased seed yield and high value-added traits such as increased grain protein and beta-glucan concentrations could provide new opportunities for growers and the food industry. Thirty-three hulless lines derived from various crosses were planted in replicated plots at two locations in Idaho. Heading date, plant height, seed yield, and test weight were recorded. Seed samples were also analyzed for protein, and beta-glucan concentrations. We found that seed yields of several lines were comparable to the hulled control cultivar. Most of the hulless lines had test weights and protein and beta-glucan concentrations that were significantly higher than hulled barley. These lines will be used for future improvement of hulless barley.

Technical Abstract: Hulless barley is considered a good source of food and feed. Hulless barley has higher feed value and is more nutritious than hulled barley. However, hulless barley is usually associated with low grain yields. Development of hulless barley with increased agronomic performance and high value-added traits such as increased grain protein and beta-glucan concentrations could provide new opportunities for growers and the food industry. Thirty-three F5 hulless lines derived from various crosses were planted in replicated plots at two locations, under irrigation at Aberdeen and under dryland conditions at Tetonia, Idaho. Agronomic data, including heading date, plant height, seed yield, and test weight were recorded. Seed samples were also analyzed for protein, beta-glucan, and lipid concentrations. Seed yields of several lines were comparable to the hulled control cultivar. Most of the hulless lines had test weights, and protein and beta-glucan concentrations that were significantly higher than hulled barley. These lines will be useful for future improvement of hulless barley germplasm.
