Research Project: Development of Novel Cool-Season Grasses and Legumes for Use in Irrigated and Non-Irrigated Dry Temperate Growing Environments

Location: Forage and Range Research

Project Number: 5428-21000-014-29
Project Type: Nonfunded Cooperative Agreement

Start Date: Feb 01, 2014
End Date: Jan 31, 2018

Objective:
The objective of this cooperative research project is to develop novel forage grass germplasm and associated management technologies for use in irrigated and non-irrigated dry temperate growing environments.

Approach:
Collaborative experiments will be designed and implemented either in the laboratory or the field for the evaluation and breeding of novel forage grass germplasm. Experiments evaluating abiotic stress responses will be conducted jointly at the Forage and Range Research Laboratory (hereafter designated FRRL) Logan, Utah, USA and at Lanzhou University, Lanzhou City, Gansu Province, China (hereafter designated LZU). Laboratory evaluations will be conducted at FRRL or LZU to include: 1) the assessment of molecular marker or DNA sequence relatedness in perennial grasses; 2) elucidation of genetic mechanisms behind value-added traits (e.g., flowering time, forage quality, seed shattering or abiotic stress tolerance) in perennial grasses, and; 3) tests to define the association of markers and traits of economic importance in perennial grasses. Germplasm evaluation of Chinese and American grass and legume accessions (cultivars and lines) will be conducted in the Great Basin Region of Utah, USA and in Gansu Province, China under irrigated and non-irrigated growing conditions as deemed appropriate. This research will attempt to: 1) develop plant materials with improved perennial grass and legume characteristics; 2) develop plant materials adapted to dry temperate regions under reduced management inputs (e.g., irrigation and fertilizer); 3) develop improved breeding procedures; 4) develop new genetic methodologies for use in evaluation and breeding, and; 5) elucidate the role of endophytes in abiotic stress (e.g., drought, salinity, and heat) environments.
