Intermediate and Preliminary Yield Trials
Forty-five experimental lines were grown in the Intermediate Malting Barley Yield Trial
at four locations (Fargo, Carrington, Langdon, and Minot) for their second year of
evaluation. Selected lines were evaluated for malt quality by the USDA-ARS Cereal
Crops Research Unit at Madison, WI and for spot blotch and net blotch reactions in
greenhouse tests conducted by Dr. Neate. Four hundred ninety eight experimental lines
were grown in Preliminary Yield Trials at Osnabrock and Fargo.
Early Generation Selections
Single spikes from the F3 and F4 generations were sown at Fargo and Osnabrock in head
rows. About 17,100 head rows representing material from 124 crosses were sown.
Selection of head rows in the field was based on maturity, plant height, straw strength,
kernel plumpness, kernel color, FHB resistance, awn type, spike length, spike erectness,
and spike density. About 1,600 selections were made and submitted to Dr. Paul
Schwarz’s laboratory (Dept. of Cereal Science) for malt quality prediction tests.
Selections were evaluated for barley kernel assortment, barley grain protein, test weight,
barley kernel color, and barley diastatic power. Spikes from the selected rows were sown
in Yuma, AZ to increase seed for 2002 yield trials. Rows from the selections with the
best malt quality estimates will be harvested and advanced to the Preliminary Yield
Trials.
Sixty-seven F2 populations were grown at Fargo and Osnabrock. Selection among and
within populations was based on the same criteria used in the F3 and F4 progeny rows.
Nine F1 populations from crosses made in the 2001-spring greenhouse were grown in the
field at Osnabrock. All F1 populations had at least one parent with partial FHB
resistance. One hundred forty two crosses were made during fall of 2001 in the
greenhouse to combine favorable agronomic characteristics, disease resistance, and malt
quality traits. Over 85% of the crosses made used parents that showed resistance to at
least one of the following diseases: FHB, spot blotch, net blotch, stem rust, leaf rust,
speckled leaf blotch, and leaf scald.
