ASSESSING DROUGHT TOLERANCE IN NATIONAL SMALL GRAINS COLLECTION (NSGC) ACCESSIONS
Small Grains and Potato Germplasm Research
2012 Annual Report
1a.Objectives (from AD-416):
The objective of this work is to assess drought tolerance in wheat accessions from the National Small Grains Collection, a problem of increasing importance in US wheat production.
1b.Approach (from AD-416):
Key accessions from the NSGC are being genotyped using DArT marker technology and SSR markers. These materials will be tested at the University of Idaho Research and Extension Center in Aberdeen for tolerance to drought. An association genetics approach will be taken to search for relationships between markers and drought tolerance. Data will be reported to the Germplasm Resources Information Network for dissemination to the plant breeding community.
We completed the initial phase of the project, which involved seed increase of small grains accessions for use in drought screening and the first season of drought screening trials. After termination of this agreement, the work will continue under project 5366-21000-027-10G. The results relate to Objective 2 of the parent project, “Strategically evaluate small grains genetic resources for priority biotic and abiotic stress resistance."
