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.
