Research Project: CREATING TURFGRASS GERMPLASM WITH IMPROVED NITROGEN AND WATER USE EFFICIENCY

Location: Floral and Nursery Plants Research

Project Number: 8020-21000-065-02-N
Project Type: Non-Funded Cooperative Agreement

Start Date: Sep 1, 2010
End Date: Aug 31, 2013

Objective:
The objective of this project is to study genetic mechanisms that could be used to improve the nitrogen use efficiency and water use efficiency of turfgrasses. Plant gene pathways that have been shown to influence nitrogen use efficiency and water use efficiency in model plant species will be evaluated in select turfgrass germplasm. The goal is to identify turfgrass germplasm that can be utilized to develop new species and cultivars requiring less fertilizer and water.

Approach:
ARS will acquire basic genetic knowledge of nitrogen and water use efficiency in turfgrass. ARS and the Cooperator will use this information to jointly develop, through classical breeding, turfgrass germplasm with nitrogen and water use efficiency. The Cooperator will study the basic signaling mechanisms of nitrogen and water use efficiency in plants.
