Progress 01/25/02 to 12/31/06
Outputs
All field work has been completed. The overall goal of the project was met. A single field collection of a local ecotype of Elymus cinereus was expanded to a 25 acre, cultivated seeding in 5 years. A field trial of this new ecotype was tested at the Aberdeen Plant Materials Center and showed a lower potential for growth and production than commercial cultivars. However, our initial work indicated that the new ecotype should perform better under drought and saline conditions in Nevada. Analysis of the data is still underway. Approximately 1,000 lbs of seed was produced from the field in 2006.
Impacts
BLM and NRCS have been briefed on the potential of the Gund accession. Approximately 1,000 lbs of seed was produced in 2006. It will be available for growers in 2007. We expect to complete a report on the accession during 2007.

Progress 01/01/05 to 12/31/05
Outputs
Twenty additional acres of Basin Wildrye (Gund variety) were seeded in spring 2005. Field work for the greenhouse study was also completed. Analyses are expected to be completed in 2006.
Impacts
BLM and NRCS have been briefed on the potential of the Gund accession. Seed has been provided to the Aberdeen Plant Materials Center and to the Lab in Logan, UT for inclusion in additional field trials.

Progress 01/01/04 to 12/31/04
Outputs
Field sampling for the greenhouse and transplant plot study is complete. We anticipate journal article submission during summer 2005. Data input is in progress and analyses are anticipated to be complete in spring 2005. An additional 90 lbs. of Gund variety basin wildrye seeds were collected from rangeland sources during summer 2004. Seed has been cleaned and tested, and will be seeded during April 2005. We anticipate this will bring our total seeded acreage to about 25 acres. We also anticipate some seed production from the 2 acres already in place.
Impacts
Two impacts are expected. First, recommendations will be made on which commercial cultivar(s)to choose for seed production under Nevada conditions. Second, the Gund basin wildrye accession utility will be assessed and recommendation for its potential use will be generated.

Progress 01/01/03 to 12/31/03
Outputs
All 3 commercial Indian ricegrass cultivars were successfully established in field plots. Morphological and physiological measurements were initiated in summer 2003. A time replication of the cultivars was also seeded in fall 2003. Field measurements will continue in summer 2004. The Gund, basin wildrye accession was also successfully established in field plots. The greenhouse study will be initiated in March 2004. Preliminary results of the field experiment have been published in abstract form.

Progress 01/01/02 to 12/31/02
Outputs
Two wild accessions of basin wildry (Elymus cinereus) were collected from field populations and planted in fall 2002. One accession each of creeping wildrye (Elymus triticoides) and needle-and-thread grass was collected from a field population and planted in fall 2001. Both were successful plantings. The generation 1 and 2 seed production will be tested against commercial varieties for performance. This is a long-term project cooperation with Bureau of Land Management to develop native seed from local ecotypes in Nevada, that can be used in fire rehabilitation efforts once quantities are commercially available.
Impacts
Native seed production is a viable alternative crop for many Nevada agriculture producers with dwindling irrigation water resources. This project will provide the intitial steps for developing a product that can serve as an alternative crop for a fledgling Nevada native seed industry.
