Mag 7 winter, waxy food barley germplasm update 2011 harvest The entries in the 2010-2011 Mag 7 trial were selected from a larger set of lines based on agronomic performance and grain beta glucan measured during three years of replicated testing in the Pacific Northwest. Earlier generation precursors to the Mag 7 were selected for disease resistance, agronomic type, and beta glucan content. All Mag7 lines are hulled and have waxy starch. Entries 1 – 2 are two-rows tracing to the pedigree Luca/Merlin, F1//Luca. Entry 3 is also a two-row, with the pedigree is Luca/Waxbar, F1//Luca. Entries 4 – 7 are six-rows tracing to the pedigree Strider/Merlin, F1//Strider. Luca and Strider are hulled, non-waxy winter two-row and six-row varieties, respectively. Luca is from Hungary and Strider was released by Oregon State University. Merlin and Waxbar are hull-less, waxy spring two rows developed by WestBred of Bozeman, Montana. Based on three years of data (2009 – 2011 harvests), three lines were advanced to head row purification in the fall of 2011: 09OR-28 (two-row), 09OR-55 (six-row) and 09OR-56 (six-row). The current plan is to select one or more for Breeders’ seed production beginning fall 2012 and to propose release in 2013. All seven lines were included in the 2011-2012 OFOOD trial for a final round of assessment and selection. The 2011 – 2012 OFOOD trial was planted at nine locations in the PNW. In the 2011 trials, grain beta glucan averaged 6% (Table 1), a value comparable to previous years. Assuming reasonable servings of whole grain foods, this level of beta glucan will easily meet recommended daily allowances. Pearled waxy barley makes an excellent rice replacement due to superior grain integrity and mouth feel. Proper recipe formulation is essential for breads made with waxy flour. Since all selections are hulled, pearling - or sieving after stone milling - will be necessary. Grain yields and test weights were competitive at all locations (Tables 2 – 8) , and in some cases they were outstanding. For example, the yield of 09-OR-56 was 9,206 lbs/acre (184 bu/acre) at Aberdeen, ID (Table 3). Quantitative resistance to stripe rust at Corvallis (the only location where this disease was observed) was good in all selections except 09OR-51, and confirmed ratings made in previous years (Table 6). Scald was observed at Corvallis and Pendleton (Tables 6 and 8); tolerance ranged from excellent (1) to acceptable (9). No winter hardiness issues were encountered. In the three years that the Mag 7 were tested in the PNW, differential winter injury occurred at Hermiston in 2009. At that location, all lines had percentage survival values > 90%. In short, the Mag 7 are agronomically competitive and aggressively seeking a market. Table 1.
