Research Project: Assessing Water and Nitrogen Use Efficiency in Nsgc Core Accessions

Location: Small Grains and Potato Germplasm Research

Project Number: 5366-21000-029-04
Project Type: General Cooperative Agreement

Start Date: Jun 03, 2011
End Date: Jan 31, 2015

Objective:
Identify NSGC accessions with enhanced nitrogen and water use efficiency (NUE, WUE) and determine the genetic basis of the traits using association mapping.

Approach:
Single-plant selections from the NSGC barley and wheat core collections will be grouped by maturity and screened in the field under varying nitrogen and water levels using an augmented experimental design. Canopy spectral radiometry and yield will be used to measure NUE and WUE. Experiments will be conducted over 5 cropping seasons. SNP data will be generated for the accessions as part of the Triticeae CAP project and data will be used to explore the genetic basis of enhanced NUE and WUE within the accessions.
