Abstract :
Crested wheatgrass (Agropyron cristatum (L.) Gaertner.) is a potential
source of low-maintenance turf species for use in areas with less water. The
main goal of this study was to evaluate turf quality characteristics of 24
crested wheatgrass specimens collected from different locations of Iran as
low-maintenance turfgrass. The experimental design was a randomized
complete block design with 3 replications. The results showed significant
variation among specimens for turf quality and turf quality components and
there were 15 specimens with an average turf quality rating of 6.0 or higher,
indicating adequate quality performance. Mowing quality were higher than 6
for all specimens and ranging from 6.30 (210 M) to 7.28 (4049). Habitats of
samples varied in performance for all traits and different geographical regions
may offer germplasm with high turf quality performance. There were significant
positive correlation between turf quality and mowing quality (r = 71**) and
also turf quality and tillering (r = 57**). Based on the results of cluster
analysis, the specimens were assigned to 3 clusters and the single specimen
from cluster 2 had the highest ratings for turf quality (7.95), mowing quality
(7.28), color (7.27) and leaf texture (7.10). These results indicated that crested
wheatgrass specimens native to Iran could be an important resource for use as
low-maintenance turfgrass.
