Project Number: 5428-21000-006-04
Project Type: Reimbursable

Start Date: Jun 29, 2001
End Date: Jun 29, 2006

Objective:
Army Material Command guidelines contain very little information about revegetation species for dry climates of the western Us. (1) Demonstration plots will be established of the new improved germplasms & monitored for target species composition, weedy species, litter & bare ground disturbance (2) Develop improved germplasm with improved traits that enhance establishment & persistence under disturbance; (3) Use molecular techniques to develop germplasm tolerant of abiotic stress.

Approach:
Improved germplasm developed from this program will be established at representative training sites in large scale plots using traditional dryland seeding methods to demonstrate improved establishment characteristics of the new experimental germplasm. Plots will be subjected to controlled disturbances by fire and army equipment. Recovery, persistence of the target species, and weed control will be monitored for several years after disturbance. AFLP and PCR-based techniques will be employed to define genetic relationships between DNA variation of the improved germplasm and geographical origin. In addition, these technologies will be used to compare the improved germplasm with natural populations of the same species. Based on data obtained, these improved germplasm will be used to conserve natural resources by army training installations in the temperate, semi-arid regions of the United States.
