Research Project: DEVELOPMENT OF TWO AND SIX-ROWED MALT, FEED, AND SPECIALTY BARLEY CULTIVARS

Location: Small Grains and Potato Germplasm Research

Project Number: 5366-21000-028-35
Project Type: Reimbursable

Start Date: Oct 01, 2010
End Date: Aug 14, 2012

Objective:
Primary objectives of this research are the development, evaluation, and release of improved winter and spring malt and specialty barley cultivars.. Included in these cultivars are 1) two and six-rowed spring and winter malt barleys, 2) two-rowed spring high beta-glucan (BG) and low phytate (LP) barley types, 3) two and six-rowed winter feed barley types and 4) two-rowed winter high beta-glucan and LP barleys. In addition, when applicable, improved germplasm will also be developed and released.

Approach:
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. The necessity to pull individual plants is the reason for the large majority of salary documented in this form. Approximately 450 crosses covering all market classes in both winter and spring backgrounds will be made each spring and spring populations advanced as previously discussed. Winter populations will be advanced in bulk under field conditions, except for specific populations which may be advanced in the greenhouse. Quality evaluations for LP will begin in the F3 stage and seed from spikes which are fixed for the LP trait will be bulked and advanced. Evaluations for BG will begin in the F5 generation and plants which show sufficient levels of BG will be advanced to F5:6 yield plots. Quality evaluation for malt quality will begin with the advanced yield trials, following at least two years of prior yield evaluation.
