    Bentgrass species are known to form very dense,uniform, and fine textured surfaces under extremelylow height of cut. As a result, they are often used forspecialized, high maintenance areas such as golfcourse fairways, tees, and putting greens. Some ofthe more popular species used for turf include creep-ing bentgrass (Agrostis palustris Huds.; synonym =A. stolonifera L.), colonial bentgrass (A. tenuis L. orA. capillaris L.), velvet bentgrass (A. canina L.), andless frequently, highland or dryland bentgrass (A.castellana Boiss. & Reut.).

    Creeping and velvet bentgrasses are best condi-tioned for the very low cutting heights necessary forgolf course greens in the United States and other re-gions of the world. Creeping bentgrasses spreadeasily through stolons and have a prostrate growthhabit, which permits the grass to persist under verylow mowing heights. Bentgrass is the most popularspecies for use on putting greens because it is highlyadapted to both the cool temperate and warm humidregions of the United States and has a highly aggres-sive, spreading growth habit. In 1954, H. B. Musserreleased Penncross, the first seeded variety of creep-ing bentgrass (Musser, 1959). Since that time, breed-ing efforts have markedly improved creeping bent-grass varieties to withstand the increasing demandsof the game of golf. Recent releases exhibit betterturf quality, higher shoot density, improved traffic, andbetter disease and stress tolerance than older variet-ies.

    Colonial bentgrass, also referred to as browntop,has traditionally been used as a lawn grass in areasof northern Europe and New Zealand that have mild(cool and humid) summers. Colonial bentgrass hasa fine leaf texture and, compared to creeping

    bentgrass, has a more upright and less aggressivespreading growth habit and is generally better adaptedfor fairway or tee use in the warmer summer climatesof the United States. Colonial bentgrass performsbest in New Jersey when mowed no lower than 3/8thof an inch. Compared to creeping bentgrass, colo-nial bentgrass typically has a brighter green color andbetter color retention during cool weather. In addi-tion, this group of grasses generally has better dollarspot resistance (caused by Sclerotinia homoeocarpa)and wear tolerance than creeping bentgrass. How-ever, colonial bentgrass varieties are much more sus-ceptible to brown patch (caused by Rhizoctoniasolani). While not lethal, the playability of golf coursesmay be affected if brown patch is not controlled oncolonial bentgrass. Current breeding efforts includeimproving brown patch disease tolerance of colonialbentgrasses.

    Velvet bentgrass forms the finest-textured andmost dense turf of the bentgrasses and can nearlyresemble green velvet when managed properly. Itspreads mainly through profuse production of erecttillers with short stolons. This grass can tolerate veryclose mowing, heat, cold, and shade, and is one ofthe most drought resistant of the bentgrasses usedfor turf (Skogley, 1973). The spread of velvetbentgrass via stolons is more aggressive than colo-nial bentgrass, but not as strong as with creepingbentgrass. Velvet bentgrass can form excessivethatch, especially at higher fertility rates and highercutting heights, and can thus become problematic ifnot maintained properly. It is also susceptible to redthread (caused by Laetisaria fuciformis) and copperspot (caused by Gloeocercospora sorghi), but hasgood resistance to dollar spot and brown patch. Seed-lings of velvet bentgrasses are susceptible to Pythium

    seedling rot during establishment. Velvet bentgrasshas not been used extensively for high maintenanceturf, largely because its range of adaptation has notbeen well recognized. Selections of velvet bentgrasshave persisted for many years in trials under NewJersey growing conditions. It is believed that the spe-cies may one day serve as a viable alternative tocreeping bentgrass for use on golf course greens, asrecent research at Rutgers indicates and culturalmanagement inputs become better known.

    The New Jersey Agricultural Experiment Stationparticipates in the National Turfgrass Evaluation Pro-gram (NTEP), which evaluates many species of turf-grass including bentgrasses throughout the UnitedStates. The Rutgers turfgrass breeding program con-ducts extensive field evaluations of collections andnew material developed in the improvement program,many of which are a result of recent collection tripswithin the United States and throughout Europe andAsia. Collections from Norway, Spain, Portugal,France, Switzerland, Italy, Greece, Poland, Bulgaria,Romania, Croatia, China, and the Slovak Republic,which are the centers of origin for many turf speciesused in the United States, serve to enhance the ge-netic diversity of the germplasm used in this breed-ing program.

    PROCEDURES

    Bentgrass evaluation trials were established atthe Rutgers Horticultural Research Farm II in NorthBrunswick, NJ in the fall of 2001 (Tables 1 through3), 2002 (Tables 4 and 5), and 2003 (Tables 6 thru 9).Two of the trials planted in the fall of 2003 (Tables 6and 8) included all entries of the 2003 NationalBentgrass Test coordinated by NTEP. Trials wereestablished on a modified Nixon loam, except the2003 NTEP putting green trial (Table 6), which wasseeded on a sand-peat root zone. Plot size was 3 X5 ft for all trials, except the 2003 NTEP trials (greensand fairway/tee) which were 4 X 6 ft. Plots were hand-seeded at a rate of approximately 0.5 lb/1000 ft2. Alltests were arranged in a randomized complete blockdesign with three replications.

    All sites were well drained and openly exposedto both sunlight and air circulation (with the exceptionof the 2003 NTEP putting green trial, which had en-closed air circulation). The annual rate of nitrogenapplied, mowing height, aerification/topdressing prac-tices, and pesticide applications for each test are pre-sented in Table 10. The putting green tests weremowed five to six times per week during periods of

    active growth with a triplex or walk-behind reel mowerequipped to collect clippings. The fairway tests weremowed and clippings were removed three times perweek with a triplex reel mower during periods of ac-tive growth. Soil pH was maintained in the range of6.0 to 6.5 with agricultural limestone. All tests wereirrigated to avoid drought stress.

    Plots were evaluated frequently during the grow-ing season for overall turf quality (i.e., turf density,texture, uniformity, color, growth habit, and presenceof damage due to diseases and insects). Turf qual-ity, spring green-up, color, density, and disease wererated on a 1 to 9 scale, where 9 represented the mostdesirable turf characteristic. Disease ratings includedbrown patch (Tables 1 and 4 to 9), dollar spot (Tables4 to 6, 8, and 9), copper spot (Tables 6, 8, and 9), andPythium blight (Table 9). All data were subjected toanalysis of variance. Means were separated usingFisher’s protected least significant difference (LSD)means separation test.

    RESULTS AND DISCUSSION

    Turf Quality Evaluations

    Entries in Tables 1 through 5 are ranked accord-ing to their overall multi-year quality average. Entriesin Tables 6 to 9 are ranked according to their turf qual-ity average in 2004. The best performing cultivars inthe 2001 putting green trial (Table 1) were two ex-perimental bentgrasses C953 and C952. Among vel-vet bentgrasses maintained under greens conditions(Table 2), the experimental cultivars PST EVU, EFD,CIS-AC1, and IVD comp, as well as the establishedvariety Greenwich, performed the best. SR 7200 didnot rank as high as the experimental selections un-der putting green mowing height (Table 2), but it wasthe top performer in the 2001 fairway trial, along withthe experimental colonial bentgrass selection SRX781-22 (Table 3). Older cultivars Penncross, Regent,Southshore, Providence, and Putter had the poorestturf quality in both the putting green (Table 1) andfairway (Table 3) trials.

    In the 2002 putting green trial (Table 4), top rank-ing entries included the recently released creepingbentgrass cultivar Declaration, three experimentalvelvet bentgrasses (EFD, CIS-AC-1, and 00BAG), andthe experimental creeping bentgrasses 007, 235050,C952, and C953. Older standard varieties such asPenncross, Pennlinks, and Providence were amongthe poorest performing entries in this study, along withKromi and 18th Green. All velvet bentgrass selec-

  • 3

    tions were among the top ranking entries. The 2002fairway/tee trial (Table 5) had less separation amongentries than the previously mentioned tests. SR 7200and the experimental velvet bentgrass EFD toppedthe list of thirty entries that comprised the best per-forming group. Two creeping bentgrasses, 235050and C953, and the experimental colonial bentgrassHCG comp were also among the best cultivars, whileProvidence, Viper, Penncross, and 18th Green creep-ing bentgrasses ranked poorly in turf quality.

    The best performing entries in the 2003 NTEPputting green trial included five velvet bentgrasses(Legendary, Greenwich, Vesper, and theexperimentals IS-AC 1 and EFD) (Table 6). The topranking creeping bentgrasses included the experi-mental selections SRX 1GPD, CY-2, and the culti-vars Declaration, Shark, and Penn G-2. In the 2003putting green trials (Tables 6, 7), Penncross, King Pin,Crenhsaw, and Southshore were among those en-tries that exhibited poor turf quality. Top ranking cul-tivars in the 2003 NTEP fairway trial (Table 8) includedSR 7200 velvet bentgrass and the creeping bentgrasscultivars Declaration, King Pin, and Benchmark DSR.Older creeping bentgrass cultivars Seaside,Crenshaw, and Penncross did not perform well. Thethree best ranking entries in the 2003 creepingbentgrass fairway/tee trial (Table 9) were Declaration,235050, and Greenwich velvet bentgrass; creepingbentgrasses Penncross, Trueline, Regent, PennLinksII, and Barbella velvet bentgrass exhibited poor turfquality.

    Dollar Spot

    While potentially one of the more damaging turfdiseases on golf courses in New Jersey, dollar spotcan be easily controlled with the use of fungicides;this can be expensive, however, because the diseaseoccurs frequently. In addition, resistance of the causalagent to fungicides is well documented. Breeding fordollar spot resistance in bentgrass is an importantobjective of the breeding program. Typically, velvetand colonial bentgrasses have better resistance todollar spot than creeping bentgrass, however the re-sults from recent trials indicate that improvements increeping bentgrass are being made. For example, inthe 2002 putting green trial (Table 4), velvet bent-grasses Greenwich, Vesper, and SR 7200, the ex-perimental selections EFD and CIS-AC-1, and TigerII colonial bentgrass had just as good resistance asthe creeping bentgrass selections HTL comp, Decla-ration, and King Pin which were selected for improvedresistance. Creeping bentgrasses 18th Green, Vi-

    per, Penncross, and the experimental SRX 1G56exhibited poor dollar spot tolerance in 2002.

    In the 2003 NTEP putting green trial (Table 6),the entries with the best dollar spot resistance includedvelvet bentgrasses (Legendary, Greenwich, SR 7200,EFD and IS-AC-1), Penn G-6, L-93, Pennlinks II, andKing Pin (creeping bentgrasses), and the experimentalcreeping bentgrasses IS-AP 9 and A03-EDI. The 2003NTEP fairway/tee trial (Table 8) consisted mainly ofcolonial and creeping bentgrass varieties. SR 7200,the only velvet bentgrass in the trial, maintained goodtolerance to dollar spot, along with the colonial bent-grass cultivars Tiger II, Revere, SR 7150, Bardot, andthe experimental selections IS-AT-7 and PST-9VN.Two creeping bentgrass cultivars, Declaration andPennlinks, also showed good dollar spot disease tol-erance. In both NTEP trials (Tables 6 and 8), thecreeping bentgrass cultivars Crenshaw and Indepen-dence exhibited weak dollar spot resistance. Manyof the entries that performed well in previous studiesalso performed well in the 2003 fairway/tee trial (Table9). Creeping bentgrasses cultivars Declaration, KingPin, Benchmark DSR, Sandhill, and experimentalsPST-OEX Bulk and PST-ORR Bulk as well as SR7200 velvet bentgrass and many experimental (PST-9IR, PST-Syn-9NT, PST-Syn-9LSD, PST-9R3, PST-Syn-9PIN, SRX 781-21, and SRX 7EE) and oldercolonial bentgrasses (Heriot and SR 7100) exhibitedhigh disease tolerance. The creeping bentgrass cul-tivar Penncross and experimental selections SRX1NJH and Bar AS2 were among the most dollar spot-susceptible entries.

    Brown Patch

    Velvet bentgrasses exhibit the greatest toleranceto brown patch of the bentgrass species used for turf.Creeping bentgrass is typically stronger than colonialbentgrass against this disease. Both the 2002 put-ting green and fairway/tee study (Tables 4 and 5, re-spectively) exemplify this. In both tests, the top en-tries were either velvet or creeping bentgrasses. Inboth tests, SR 7200 velvet bentgrass, the experimen-tal selection EFD velvet bentgrass, and the creepingbentgrasses Benchmark DSR and 235050 wereamong the top entries. Experimental selections PST-SynA1U and PST-9VL Bulk, and the cultivars Revereand Viter exhibited the greatest disease tolerance ofthe colonial bentgrass entries evaluated (Table 5).

    Results from the 2003 NTEP putting green trial(Table 6) indicated that the velvet bentgrass Legend-ary, the experimental selections IS-AC 1 and EFD,

  • 4

    and one experimental creeping bentgrass, SRX1GPD, exhibited the highest levels of resistance tobrown patch. Penncross, Alpha, and Bengal showedlow levels of brown patch disease resistance. All en-tries in the 2003 putting green trial (Table 7) weremoderately tolerant of brown patch; Shark and Inde-pendence, however, performed the best. In the 2003NTEP fairway/tee trial (Table 8), no colonialbentgrasses exhibited acceptable levels of toleranceto brown patch. Many of the creeping bentgrasses(Declaration, Shark, 235050, and Penneagle II andthe experimental selections T-1, PST-OEB, SRXIPDH, and IS-AP-14), however, and the velvetbentgrass SR 7200 showed extremely high levels ofbrown patch resistance. Colonial bentgrass cultivarsTiger II (Tables 4, 5, and 8), Bardot, and SR 7150(Table 8), experimental colonial bentgrass selectionsSRX 781-21 and SRX 7MOBB (Tables 4 and 9), andcreeping bentgrass cultivars Regent (Tables 1 and9), Penncross (Tables 1 and 6), and Trueline (Tables4 and 9) were among those entries with poor resis-tance to this disease. It is interesting to note thatAlpha had exhibited poor brown patch resistance un-der putting green maintenance, but was one of themost resistance creeping bentgrass cultivars in thefairway trial.

    Spring Green-Up

    Spring green-up data was collected for all 2001and 2002 trials (Tables 1 to 5). In general, the colo-nial bentgrasses exhibit the best green-up qualitywhen compared to both creeping and velvetbentgrasses. There were several creeping bentgrassentries that possessed early green-up qualities; theseincluded cultivars Benchmark DSR (Tables 4, 5), Dec-laration (Table 4), 007 (Table 4), Penneagle andPennlinks (Table 1), and experimental creepingbentgrass entries C952 (Tables 1, 3), SRX R1E2, SRX1G44, SRX 1G32 (Table 1), and SRX 1GPinkD (Table4). Creeping bentgrass cultivars Trueline, Brighton,

    and 18th Green (Tables 4, 5) were consistently poorranking entries, as were experimental selections MS6,MS7, MS4, 7CMS4, and 7RMS4 (Table 1). In the2001 fairway trial (Table 3), the experimental colonialbentgrass selections 9BNC-2001, 9ER Blk-5 Bulk,HCDR comp, and IBP comp exhibited the earliestgreen-up; and experimental colonial bentgrass selec-tions SRX IDIN, SRX 765-11, SRX 767-7, and culti-var SR 7150 were among entries in this test that werepoor in ranking. In the 2002 fairway trial (Table 5),the colonial bentgrass cultivar Glory and experimen-tal selections HCG comp, HCF comp, and PST-9BNCwere the top ranking entries. The best creepingbentgrasses in this trial were Benchmark DSR andKing Pin. In the velvet bentgrass putting green trial(Table 2), SR 7200 and CIS-AC1 exhibited strongspring green-up, while IVM comp and IVD compranked lowest.
