“…Dietary BG also reduces human glycemic response and has potential in management of diabetes and associated health risks (Chen and Raymond, 2008). Indeed, new barley cultivars with enhanced BG content are being developed specifically for the food industry (Obert et al, 2011(Obert et al, , 2012Hu et al, 2016).

The content of (1→3, 1→4)‐β‐glucan (BG) in barley (Hordeum vulgare L.) has become a breeding target due to the human health benefits of BG. More than 20,000 barley accessions from the USDA National Small Grains Collection (NSGC) have been assayed for BG content and the data recorded in the Germplasm Resources Information Network (GRIN). This study classified barley accessions as high or low BG content using the GRIN data, analyzed the relationship of BG content with the geographic origin of accessions and other barley descriptors, and verified the analysis with two replicated field experiments using a total of 829 accessions. Content of BG varied with geographic origin and spike‐row type. Accessions from Asia and Africa had higher frequencies of high‐BG‐content accessions and those from Europe and the Americas had higher frequencies of low‐BG‐content accessions. Two‐row accessions were more often classified as high BG content than six‐row types. There was no significant relationship between accession improvement status (e.g., landrace vs. either cultivar or breeding line) and BG content. The geographic differences among barley accessions likely correspond to the ecogeographic classification of barley and end‐use needs, such as malting vs. food barley, that vary by origin. Genebank databases should be expanded to include classification of relative BG content to make the data more readily useful to plant breeders.

Barley (Hordeum vulgare L.) has a storied history as a food crop, and it has long been a dietary staple of peoples in temperate climates. Contemporary research studies have focused mostly on hulled barley for malt and animal feed. As such, nitrogen (N) and seeding rate agronomic data for naked food barley are lacking. In this study, we evaluated the effects of N on ß-glucan and protein content, and N and seeding rate on phenotypic characteristics of naked food barley, including grain yield, emergence, plant height, days to heading, days to maturity, test weight, percent plump kernels, and percent thin kernels. Experiments were conducted at two no-till farms, located in Almota, WA, and Genesee, ID, in the Palouse region of the Pacific Northwest from 2016 to 2018. The experiment comprised two varieties (“Havener” and “Julie”), employed N rates of 0, 62, 95, 129, and 162 kg N ha−1, and seeding rates of 250, 310, and 375 seeds/m−2. Increased N fertilization rate was shown to significantly increase all response variables, except β-glucan content of the variety Julie, days to heading, test weight, and percent plump and thin kernels. Increased N fertilization resulted in higher mean grain yield of Havener and Julie in both Almota and Genesee up to 95 kg N ha−1. Havener had higher yields (3,908 kg N ha−1) than Julie (3,099 kg N ha−1) across locations and years. Julie had higher β-glucan (8.2%) and protein (12.6%) content compared to Havener (β-glucan = 6.6%; protein = 9.1%). Our results indicate that β-glucan content is associated with genotype, environmental, and agronomic factors in dryland cropping systems of the Palouse.

“…Most of the food barley cultivars currently used in the United States contain medium levels of b-glucan (6-8% dry matter based), including 'Julie' (Obert et al, 2013), 'CDC Alamo' (Rossnagel et al, 1999), 'Kardia' (Hu et al, 2016), and ones from WestBred Co., 'Salute', 'BG006', and 'BG012'. 'Transit' (Obert et al, 2011) has a high b-glucan concentration, averaging between 90 and 100 g kg -1 .…”

Goldenhart' (Reg. No. CV-368, PI 688445) is a two-rowed spring hull-less food barley (Hordeum vulgare L.) developed by the USDA-ARS, Aberdeen, ID, in cooperation with the University of Idaho Agricultural Experiment Station, and released in 2017. Goldenhart is derived from the cross of 02HR 4590/'CDC Fibar' and was advanced through modiied bulk pedigree F 1 -F 5 . Goldenhart was tested at the USDA-ARS, and all other cooperative trials, as line 2Ab09-X06F058HL-31. Goldenhart was tested over 40 location years and has shown better yield under irrigated conditions than 'CDC Alamo' and 'Transit' and better yield in dryland areas than all the current two-rowed spring hull-less food barley cultivars, 'Julie', Transit, and CDC Alamo. Moreover, Goldenhart has shown signiicantly higher yields than Transit, the barley check with similar b-glucan concentration, in both irrigated and dryland conditions. Goldenhart will be a good hull-less cultivar and a better alternative than Transit in the food barley production market.
