Description

Genus and species: Cynodon dactylon (L.) Persoon.

Variety denomination: ‘BARAZUR’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct Bermuda grass plant designated ‘BARAZUR’ and botanically known as Cynodon dactylon (L.) Persoon. This new Bermuda grass was developed from research germplasm collections near Sydney, Australia in 1997. Germplasm selected from the 1997 evaluation was then evaluated in turf plots in southern France from 1998 to 1999. The most promising germplasm was selected and designated ‘BARAZUR’, which is also known as ‘BAR 1CD3’. ‘BARAZUR’ was then sent to Virginia for further evaluation and selection. A selection was made in 2000 in Virginia for its turf quality. The present invention has been found to be stable and reproduce true to type through successive asexual propagations.

Plant Breeder's Rights for this plant were applied for in The Netherlands and Community Plant Variety Rights in Europe in 2001 and granted in 2003 and 2004 respectively; both were withdrawn in 2006. Both applications were given the title ‘BARAZUR’. ‘BARAZUR’ has not been made publicly available more than one year prior to filing of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Raleigh, N.C., Savelletri di Fasano, Italy, Las Cruces, N. Mex., and Wharton, Tex.

    • 1. Rapid lateral spread that forms a dense sod;
    • 2. Minimal thatch;
    • 3. Minimal vertical growth that requires very little mowing; and
    • 4. Very low number of inflorescences (seed heads) produced.

DESCRIPTION OF THE PHOTOGRAPH AND FIGURE

This new Bermuda grass plant is illustrated by the accompanying photograph taken in Wharton, Tex., on May 6, 2009.

FIG. 1 shows a photo of the invention 30 days after mowing.

FIG. 2 shows a tree diagram of the genetic linkage distance of ‘BARAZUR’ with five other Bermuda grass cultivars.

 DESCRIPTION OF THE NEW VARIETY

The following description of ‘BARAZUR’ is based on observations taken during the 2003 to 2009 growing seasons in Raleigh, N.C., Savelletri di Fasano, Italy, Las Cruces, N. Mex., and Wharton, Tex.

Table 10 shows a written comparison of various Bermuda grass varieties when compared with ‘BARAZUR’. Data is from Wharton, Tex., with a planting date of Jun. 13, 2008. As shown in Table 10, ‘BARAZUR’ is distinguished from other Bermuda grass varieties by its blue green color, very low vertical growth, tight and dense growth, short leaf, little or no scalping when mowed, and no seed head production.

TABLE 10 Comparison of Characteristics of Various Bermuda Grass Varieties Plateau Blue green color; low vertical growth; tight and dense; short leaf; little or no scalping when mowed; some seed heads produced. Patriot Yellow green color; tall vertical growth; thin in turf; course leaf; scalped when mowed; numerous seed heads produced. ‘BARAZUR’ Blue green color; very low vertical growth; tight and dense; short leaf; little or no scalping when mowed; no seed heads produced. Celebration Blue green color; medium vertical growth; thin; coarse leaf Tifton 419 Light green in color; tall growth; thin, fine leaf blades, scalping when mowed.

An analysis of the genetic relationship between ‘BARAZUR’ and various Bermuda grass samples was conducted in the fall of 2009. Amplified Fragment Length Polymorphism (AFLP) markers were used in the analysis. From each DNA-sample, three independent EcoRI/MseI pre-amplifications were prepared. This rendered a total of eighteen pre-amplifications for analysis and allowed a check of the reproducibility of the AFLP-protocol when the same DNA-sample was used repeatedly for analysis. For each pre-amplification, eight AFLP primer combinations were used. Six primer combinations were used as taught by Wu et al., Genome 47:689-696 (2004) and are shown in Table 11. Primer combination e-GCTG/m-CAG, as taught by Wu et al. (2004) was replaced by the primer combination e-ACA/m-CAG to avoid the necessity to carry out two preamplifications for each sample in triplicate. Primer combination e-AGT/m-CAG was replaced by primer combination e-ACA/m-CAT, to avoid unnecessary delay in the completion of the analysis. An ABI Prism 3130×1 capillary sequencer was used for the AFLP-fragment separation and detection. GeneScan 500 Rox labelled size standard was loaded in each run to allow fragment sizing. The fluorescent AFLP fingerprints were scored using Genemapper v. 3.7 (Applied Biosystems) and the presence or absence of each marker in each sample was recorded. As shown in Table 12, the presence or absence of each marker was used to construct a scoring table where a score of 1 equalled presence and a score of 0 equalled absence for data analysis. Genetic similarity between pairs of samples was estimated using the percentage of shared AFLP bands. This coefficient varies between 0 (complete dissimilarity) and 1 (complete similarity). Calculations were carried out in STATISTICA v8.0 (Stat Soft Inc., Tulsa, Okla., USA).

TABLE 11 Restriction Enzymes and Selective Nucleotides Used, Primer Combinations as cited by Wu et al. (2004) EcoRI MseI PC1* ACT CAG PC2* AAC CAG PC3 ACA CAG PC4* ACT CAT PC5* AAC CAT PC6* ACT CAC PC7* AAC CAC PC8 ACA CAT

As shown in Table 11, eight primer combinations were used. These eight primer combinations rendered 373 polymorphic AFLP-bands for analysis. The fingerprints generated for replicated samples were compared. In most cases three repetitions were available for analysis for a given primer combination. Only a few differences were encountered when replicated samples were compared: for Patriot only one AFLP-band (PC8_al7) was not consistent among the three replications. For ‘BARAZUR’ only the AFLP-band PC3_al35 was not consistent among the three replications and for Tifway 419 only the AFLP-band PC7_al35 was not consistent. For Tifdwarf, Celebration, TifEagle and ‘P-18’ the replicates were identical. This demonstrated a high reliability of the results obtained.

As shown in Table 12, the analysis shows that the Bermuda grass varieties Tifdwarf, TifEagle and ‘P-18’ display an extremely high degree of similarity. No single polymorphism was detected between samples Tifdwarf and TifEagle among the 373 AFLP-bands screened. One single polymorphism (for band PC6_al29) was found between Tifdwarf and TifEagle, on the one side, and ‘P-18’ on the other side.

The genetic relationships among the Bermuda grass samples tested have also been represented using Unweighted Pair Group Method with Arithmetic Mean clustering UPGMA (FIG. 2). As shown in FIG. 2, four clusters are evident with Tifway 419 being the most dissimilar, and TifDwarf, TifEagle, and ‘P-18’ being the most similar of the group.
