Development of Improved Barley Cultivars for Idaho
Small Grains and Potato Germplasm Research
2012 Annual Report
1a.Objectives (from AD-416):
Development of barley varieties and germplasm. We aim to improvement of barley cultivars with desired agronomic and quality traits that will benefit growers and industry. The long term goal is to develop and release new barley cultivars that have better yield potential plus either superior malting quality for malting barley or better nutrient quality for food barley.
1b.Approach (from AD-416):
The proposed work involves using both traditional breeding approach and molecular approaches. The traditional breeding approach will be used in crossing, evaluation, and selection. All the material advancement will be conducted in field, greenhouse, and winter nurseries. The molecular work will focus on the molecular marker identification for their linkage to important traits. Utilizing existing testing locations and off-season winter nurseries for the F2 and F4 generations, populations will be advanced to the F5 generation in bulk and F5:6 lines derived for yield evaluation. Lines will be derived from plants as opposed to spikes, and will therefore begin yield evaluation directly following derivation. Quality evaluation for malt quality will begin with the advanced yield trials, following at least two years of prior yield evaluation
The winter program progressed well and two lines were entered into the Western
Malting Barley Trial. An elite line winter nursery was planted with 22 2-row
and 30 6-row malting barley lines for yield testing at Aberdeen and Filer,
Idaho during the 2011-12 season. This project is directly related to parent project objective 3, “Develop improved barley meeting the needs of conventional and specialty markets for both dryland and irrigated production systems”.
