DT-1
Type: Other or unclassified name

Narrative
DT-1 was selected during 2001 because it maintained quality and green color longer than the other genotypes when under drought stress. It has been further tested since 2002 in 19 drought-stress trials, two traffic-stress trials, and four irrigated, non-stress trials. These replicated field tests were carried out in Georgia, Florida, North Carolina, Oklahoma, and Texas. DT-1 was entered into the 2013 National Turfgrass Evaluation Program (NTEP) trials where it will be evaluated in 20 locations across the United States until 2017. DT-1 generally has superior turfgrass performance than many other cultivars when in short- and long-term drought environments. Research to date indicates that the mechanism of DT-1's drought tolerance may be reduced water use, particularly in soils with higher silt and clay content. DT-1 has at least equal turfgrass performance, if not superior, to many other cultivars when well-maintained with regards to irrigation, fertilization, and mowing frequency. DT-1 generally has superior traffic tolerance than many other cultivars when subjected to wear. The mechanism of DT-1's traffic tolerance may be increased turf cover, particularly in the fall, and faster growth. A potential limitation of DT-1 is that it can scalp when mowing frequency is not regular in environments where soil water and nutrient availability are not limiting. DT-1's potential to scalp has not been an issue in stress environments.

Pedigree
Description:
In 1992, seven C. transvaalensis (T-572, T-573, T-573, T-574, T-575, T-576 and T-577) parents were crossed with four C. dactylon (T-90, T-110, 'Quickstand', and 'VaMont') parents in Tifton, GA. Cross pollinations were made in the field by surrounding each C. transvaalensis parent with a C. dactylon parent in 1.9 m2 (6 ft2) plots. All crossing blocks were in close proximity of each other, so intercrossing between and among plots cannot be ruled out.
