Tift 94 is a vigorous triploid (2n=3x=27 chromosomes) which has use on golf course fairways and tees, athletic fields, lawns, commercial landscape sites, and other turf areas where a fine-textured, low growing turf is desired. The grass produces less upright growth and has shorter and narrower leaves, and shorter internodes than Midiron from which it was developed and Tifway, two commercially available cultivars. It produces more shoots per node than Midiron. It has better color and turf quality than Midiron.

1. A new and distinct cultivar of Bermudagrass plant, substantially as herein shown and described, distinguished by the fine textures of the leaf blade, short internodes, and improved color which produces a low growing turf with improved density and quality.

|||||||||||||||||||||||||
Bermudagrass, Cynodon dactylon (L.) Pers. is a warm-season perennial sod-forming grass that spreads by stolons and rhizomes. Bermudagrass probably originated from Africa and South and Southeast Asia but it has been introduced to all tropical and subtropical regions of the world.
The species has been observed to survive at 50° N in Europe and to 4000 m elevation in the Himalayas. It is also found on islands in the Pacific, Atlantic and Indian Oceans.
Roots and rhizomes of this species can penetrate the soil to a depth of 1 m or more. A large amount of morphological variability exists in this species.
Both common and triploid hybrid types are used for turf. Common types have 2n=18 or 36 chromosomes and produce seeds. Triploid hybrids have 2n=3x=27 chromosomes and are male and female sterile. Both can be propagated by stolons and/or rhizomes. Only common bermudagrass types can be propagated by seeds.
Bermudagrass can be used to produce an attractive wear-resistant turf if managed properly. Midiron is a medium coarse 2n=3x=27 chromosome hybrid released by the Kansas Agricultural Experiment Station in 1971 for use in USDA plant hardiness zone 6 (USDA Agricultural Handbook 170). It is reported to be an interspecific cross between a C. dactylon selection (used as female) from N. Platte, Nebr. and Ugandagrass (C. transvaalensis) as male. Tifway is a fine 2n=3x=27 chromosome hybrid released by the USDA-ARS and the Georgia Coastal Plain Experiment Station in 1960. Tifway is adapted to USDA plant hardiness zones 7, 8, 9 and 10 and similar areas around the world. Tifway is planted on a larger area around the world than any other improved triploid turf bermudagrass because of its dark green color, fineness, wear-resistance and persistence. However, Tifway does not survive reliably in USDA plant hardiness zone 6 and in the northern half of zone 7. Midiron is much coarser than Tifway and does not produce as high quality turf.
The popularity of Tifway produces a potential genetic vulnerability problem in that a single vegetatively propagated genotype is planted over a large area. Development of genetically different fine-textured genotypes would lessen the threat of the industry having a suitable grass to plant if one genotype suddenly became susceptible to a pest.
It was anticipated that Tifway 2 (released in 1991) would become a more popular cultivar to plant than Tifway. However, Tifway continues to be the most popular cultivar for fairways, tees, athletic fields, lawns and recreational areas because it performs as well or better than Tifway 2 under most circumstances.
Mutagens have been used to induce dwarfness in numerous crops. An induced fine-textured mutant in Midiron would combine winterhardiness and high turf quality in another genotype.
FIG. 1 is a photograph of 40 day old stolon growth of Tift 94 and Midiron (the commercial cultivar from which Tift 94 was developed) showing the fine texture due to shorter and narrower leaves and shorter internodes of Tift 94.
FIG. 2 is a photograph of thirty-two day shoot growth from 10 cm sod plugs of Tift 94, Midiron and Tifway in the greenhouse showing the shorter shoot growth of Tift 94 and the higher density of shoots from Tift 94 compared to Midiron.
FIG. 3 is a photograph of Tift 94 mowed at 12 mm three times per week showing the dense high quality turf produced by this cultivar.
Tift 94 is a vigorous triploid (2n=3x=27 chromosomes) which has use on golf course fairways and tees, athletic fields, lawns, commercial landscape sites, and other turf areas where a fine-textured, low growing turf is desired. The grass produces less upright growth and has shorter and narrower leaves, and shorter internodes than Midiron from which it was developed and Tifway, two commercially available cultivars. It produces more shoots per node than Midiron. It has better color and turf quality than Midiron.
Bermudagrass Tift 94 is a fine-textured mutant selected from plants established from dormant stolons of the Midiron cultivar of Cynodon dactylon (L.) Pers.×C. transvaalensis Butt-Davy treated with 8000 rads of Cobalt 60 gamma radiation on Jan. 20, 1983. Dormant stolons of Midiron were obtained from Ralph White of Southern Turf Nursery. Radiation treated stolons were planted in steam-sterilized soil in flats in the greenhouse immediately after treatment. Sixty-six fine-textured mutants or sectors were selected on stolons, separated from the stolon and individually propagated. Tift 94 was one of the 66 single plant selections and was tested as MI40 in tests in Tifton, Ga.; Stillwater, Okla.; Lexington, Ky.; and Lake Wales, Fla.; Ft. Bluff, Tenn. and Lincoln, Nebr.
Tift 94 is a finer-textured mutant induced with radiation in the Midiron cultivar of bermudagrass. It has 2n=3x=27 chromosomes like Midiron. Initially at Tifton, Ga., `Tift 94` has been vegetatively propagated by shoots, stolons or rhizomes through plugging, sprigging and sodding. Tift 94 is a single genotype that produces a uniform turf. It has been propagated true-to-type from 1983 to 1995.
Tift 94 has been evaluated in 12 experiments at six locations. In all experiments except at Stillwater, Okla., the Bermudagrass entries were replicated and the data analyzed statistically. Significant refers to the P=0.05 probability level.
After eight years of mowing three times per week at a 25 mm height, Tift 94 produced significantly better quality turf (8 on scale where 9 is best) than Midiron (5.8) under medium fertility and management. In another test, mowed three times per week at 12 mm for six years, Tift 94 averaged an 8.4 turf quality rating while Midiron was rated 2.6. The fine-textured characteristics of Tift 94 allows it to produce better quality turf under close (12 mm and 25 mm) and frequent cutting. Compared to Tifway and Tifway 2, Tift 94 had similar or slightly higher turf quality ratings.
Based on color ratings, Tift 94 was significantly greener than Midiron in April, November, December and January. Tift 94 began growing (greenup) earlier than Midiron in 1993 but not in 1991. Color ratings for Tift 94, Tifway and Tifway 2 are similar.
In the fall of 1993, Tift 94 plots had fewer mole crickets than most of the major commercial turf cultivars. No differences were observed in mole cricket ratings. between Tift 94 and Tifway in 1995; both showed low (0.5) infestation on a scale of 1 to 5 (where 5 is severe).
Tift 94 has produced good quality turf as far north as Lexington, Ky.; Stillwater, Okla.; and Ft. Bluff, Tenn. and as far south as Lake Wales, Fla. Tift 94 was the only one of six midiron mutants planted at Lincoln, Nebr. that survived the 1990-91 winter.
Tift 94 establishes at about the same rate as Tifway and Tifway 2.
Shoot growth (thirty-two days) from 10 cm plugs growing in the greenhouse in October was 10.7 cm tall for Tift 94 and 20.6 cm and 14.9 cm for Midiron and Tifway, respectively. Leaf length was shorter (5.6 cm) for Tift 94 compared to 10.7 cm for Midiron and 7.0 cm for Tifway. Leaves of Tift 94 were narrower (1.2 mm) compared to 2.2 mm for Midiron and 1.4 mm for Tifway. More than five times as many shoots were produced from a 10 cm plug of Tift 94 (475) compared to 87 for Midiron.
In a three year old sod mowed weekly at 3 cm, internode lengths of horizontal stolons and vertical shoots were shorter for Tift 94 (1.2 cm and 0.6 cm, respectively) than for Midiron (2.5 cm and 1.0 cm) and Tifway (1.5 cm and 0.8 cm). Tift 94 also had shorter and narrower leaves (1.5 cm and 1.2 mm, respectively) than Midiron (2.0 cm and 1.9 m/m) and Tifway (1.6 cm and 1.2 mm).
Internode length of stolons in a juvenile growth stage on 40 day old plants in the field were in general similar for Tifton 94, Midiron and Tifway. The fourth and fifth internodes were shorter for Tift 94 and Midiron (22 or 23 mm) compared to Tifway (26 mm). Shoot numbers per node were similar for Tift 94 (1.2 to 2.7) and Tifway (1.2 to 2.6) but higher than for Midiron (1.0 to 1.5). Leaf length of Tift 94 was shorter (1.4 cm) than that of Midiron (1.9 cm) and Tifway (1.7 cm). Leaf width was the same for Tift 94 and Tifway (1.7 mm) but narrower than Midiron (2.3 mm).
