WINTER BARLEY
The winter barley breeding program has produced both six-rowed and two-rowed
selections with promising malting quality characteristics that have the potential to
compete with existing spring malting barley varieties. The six-rowed winter selection
88Ab536-B (NE 76129/Morex//Morex) continues to be tested in regional trials and used
extensively as a parent in barley breeding programs designed to develop winter six-rowed
malting barleys. The selection 88Ab536-B has been evaluated in AMBA-sponsored
evaluations of malting and brewing quality and appears to have malting quality
characteristics similar to the recurrent parent Morex. This selection was included in the
2001 AMBA pilot-scale tests, mainly as a check variety for winter malting barley
Agronomic data for 88Ab536-B and other six-rowed winter barley varieties and
selections are shown in Table 17.
Additional winter barley selections of interest include several two-rowed winter barleys
with promising yield and malting quality characteristics. Two-rowed winter barleys
prominent in the program include 94Ab1269 (MT81616/81Ab1702), 94Ab1274
(MT81616/81Ab1702), and 95Ab2299 (ORWM8406/Harrington). Agronomic data for
these selections plus selected winter barley varieties are shown in Table 18, and malting
quality data in Table 19. The selection 94Ab1274 was submitted in 2001 for a third year
of AMBA pilot-scale evaluations. This is believed to be the first two-rowed winter
selection submitted for AMBA pilot-scale evaluations. In addition, Oregon State
University selections STAB 7, STAB 47, and STAB 113 were also planted in this drill
strip series in September 2000 and submitted in 2001 for AMBA pilot-scale evaluations.
The 2000-01 Aberdeen winter barley nursery included 100 entries in replicated yield
trials. Eighty entries were grown in a 2000-01 nonreplicated nursery and over 6500
headrows were evaluated. In addition, the 2000-01 winter barley nursery included two
replicated trials of winter barleys developed at Oregon State University, one replicated
trial of Russian Wheat Aphid resistant materials from Oklahoma plus over 100
observation plots and 600 headrows. The 2000-01 winter barley trials were the most
extensive winter barley trials ever planted at Aberdeen and all of the trials had good
winter survival. Named varieties planted in the current replicated trials include ‘Boyer’,
‘Cyclone’, ‘Eight-Twelve’, ‘Fanfare’, ‘Hesk’, ‘Hundred’, ‘Kamiak’, ‘Kold’, ‘Mathias’,
‘Merian’, ‘Opal’, ‘Petula’, ‘Pipkin’, ‘Plaisant’, ‘Puffin’, ‘P721’, ‘P954’, ‘Rifle’,
‘Schuyler’, ‘Scio’, ‘Sprinter’, ‘Strider’, and ‘Sunstar Pride’. Agronomic data for three
years of testing at Aberdeen are shown in Table 16.
