`TDS-BM1` is a new and distinct variety of bermudagrass (Cynodon dactylon)
discovered by me under a heavily trafficked cultivated, mowed turf in a
home lawn in Las Cruces, N. Mex. TDS-BM1 spreads rapidly by both stolons
and rhizomes. TDS-BM1 is suitable for use as turf on golf course fairways,
sports fields, home lawns, industrial sites, and other sites wherever
bermudagrasses are adapted. TDS-BM1 was identified for its diminutive
growth pattern, finer leaf texture, and persistence under heavy traffic as
compared to surrounding bermudagrass. TDS-BM1 was asexually propagated by
me in Las Cruces, N. Mex. by cutting of stolons and rhizomes, rooting them
in soil, and planting of the rooted stolons and rhizomes to provide
planting stock for studying performance and for comparisons with
commercial varieties. TDS-BM1 remained stable in both performance and
morphological characters after propagation.
A bermudagrass designated C84-135 was disclosed in U.S. Pat. No. P.P.
6,278, issued on Sep. 6, 1988. A bermudagrass designated CT-2 was
disclosed in U.S. Pat. No. P.P. 6,841, issued on Jun. 6, 1989. A
bermudagrass designated World Feeder was disclosed in U.S. Pat. No. P.P.
7,081, issued on Dec. 19, 1989. A bermudagrass designated Midlawn was
disclosed in U.S. Pat. No. P.P. 8,162, issued on Feb. 23, 1993. Another
bermudagrass designated Midfield was disclosed in U.S. Pat. No. P.P.
8,168, issued on Mar. 2, 1993.
TDS-BM1 is distinguished from other varieties of bermudagrass by the
combination of characters of turf performance, shade tolerance, white
anthers, leaf texture, culm production, and a distinct DNA fingerprint.
FIG. 1-3 are DNA fingerprints of bermudagrass varieties. The RAPD analysis
illustrate TDS-BM1 is different from both Tifgreen and Tifway.
FIG. 4 is a photograph of a stolon of TDS-BM1.
TDS-BM1 is a new and distinct variety of bermudagrass that spreads by
stolons and rhizomes. TDS-BM1 is a bermudagrass similar in appearance to
Tifgreen and Tifway. TDS-BM1 had a mean stolon internode length of 33.3 mm
for nodes 2 through 4 with Tifgreen having a mean of 35.8 mm in
measurements on greenhouse grown plants. The leaf blade width of the third
youngest leaf on TDS-BM1 was 1.99 mm with Tifgreen having a mean of 2.25
mm. The diameter of the third node on a vegetative stolon of TDS-BM1 was
0.87 with Tifgreen having a mean of 0.99.
In trials in Gainseville, Fla., TDS-BM1 was reported as having high
seasonal turf quality in 1993 with a mean of 6.87, and was statistically
higher in quality than Tifgreen (Table 1). TDS-BM1 was also higher in
quality than Tifgreen in 1994 in Florida trials (Table 2). In the 1992 and
1993 NTEP trials in Texas, TDS-BM1 ranked second and first in quality of
26 entries. In color ratings of vegetative bermudagrasses, TDS-BM1 is not
statistically different from Tifgreen or Tifway (Tables 3,4). In addition,
in the 1992 and 1993 NTEP Trials, TDS-BM1 had a mean color rating of 6.7
in both years. TDS-BM1 has a fine textured leaf blade compared to
Midfield, Midlawn, and Midiron (Table 5). In the 1992 NTEP trials
(TAES-Dallas), TDS-BM1 was reported to have a statistically finer leaf
blade than Midlawn, Midiron, Midfield, Texturf 10, and STF-1 in both 1992
and 1993.
TDS-BM1 has a rapid rate of spread (Table 6). Under shaded conditions,
TDS-BM1 maintains higher percent plot cover compared to Tifgreen (Table
7,8). In trials in Mississippi, TDS-BM1 was statistically earlier in
greenup than 16 entries in the National Bermudagrass Trial for 1993 and
1994 (Table 9). In the 1993 NTEP report from Mississippi, TDS-BM1 reported
the second highest spring greenup rate of 26 varieties at 11 different
locations.
TDS-BM1 has the highest number of seedheads in the Florida trials in 1993
(Table 1). TDS-BM1 had the highest seedhead production in trials in Dallas
(Table 10-12). TDS-BM1 has white anthers, similar to Tifgreen and Midfield
(Table 13).
TDS-BM1 showed lower salt injury than Midiron, Texturf 10, and STF-1 in
evaluations of percent shoot salt injury at Texas A&M -Dallas, of the 1992
National Turfgrass Evaluation Program (Table 14). TDS-BM1 showed higher
susceptibility to pink snow mold than Midfield, Midiron, or Midlawn (Table
15).
TDS-BM1 shows a distinctly different DNA from Tifgreen using RAPD analysis
using a single primer of an arbitral oligonucleotide referred to as JAP 29
(FIG. 1) of JAP 26 (FIG. 2). Both TDS-BM1 and Tifgreen may be
distinguished from Tifway using a single primer of an arbitral
oligonucleotide referred to as JAP 26 (FIG. 2) and JAP 25 or JAP 27 (FIG.
3).

Takefumi Omura of Japan Turfgrass Inc. performed the DNA fingerprint
analysis. The bermudagrass DNA fingerprints were TDS-BM1, Tifgreen, and
Tifway. The DNA fingerprints were produced by extractions from the leaf
tissue of the vegetatively propagated clones. The results of the DNA
fingerprint analysis are summarized:
TDS-BM1 shows a distinctly different DNA from Tifgreen using RAPD analysis
using a single primer of an arbitral oligonucleotide referred to as JAP 29
(FIG. 1) or JAP 26 (FIG. 2). Both TDS-BM1 and Tifgreen may be
distinguished from Tifway using a single primer of an arbitral
oligonucleotide referred to as JAP 26 (FIG. 2) and JAP 25 or JAP 27 (FIG.
3).
