‘FMC-6’ bermudagrass [Cynodon dactylon (L) Pers.] (Reg. no. CV-45, PI 584451) is a seed-propagated, turf-type cultivar released in 1995 by Pennington Seed/Seeds West. FMC-6 was tested under the experimental designations FMC-K and FMC 6-91.

FMC-6 is an open-pollinated cultivar with the original polycross consisting of 14 parent clones selected for shorter internode length, dark-green color, fine leaf texture, cold tolerance, and bermudagrass stunt mite (Eriophyes cynodoniensis Sayed) resistance. The initial parentage traced back to the following points of origin: 43% Arizona, 21% France, 18% New Mexico, 11% Florida, and 7% unknown. The 14 clones are 16-1 (Cochise County, AZ), 17-2 (progeny of NM30), 17-3 (Unknown), 17-8 (progeny of FB-49), 17-20 (Dona Ana County, NM), 23-6 (Yuma County, AZ), 23-7 (Yuma County, AZ), 23-10 (Yuma County, AZ), 23-18 (Yuma County, AZ), 23-24 (Yuma County, AZ), 17-24 (progeny of 8 clone polycross–NM32, NM30, FB49, F29, FB133, R9P1, NM10, and NM2), K-17-3 (France), K-21 (France), and K-17-20 (France).

The original polycross consisted of seven replications and was made in 1989 at Las Cruces, NM. Seed was harvested in bulk and then subjected to three cycles of phenotypic recurrent selection. Each cycle of selection was initiated by establishing 300 individual plants from seed in Cone-tainers (Stuewe and Sons, Inc., Corvallis, OR) in a greenhouse during the winter. The plants were evaluated for approximately three months, and 100 plants that exhibited short internodes, slower vertical shoot elongation, finer leaf texture, darker green color, and absence of bermudagrass mite damage were selected. The selected plants were transplanted in the field in isolation and allowed to interpollinate. Seed was bulk harvested and used to start another cycle of selection. A Breeder seed field was established with plants from the third cycle of selection at Yuma, AZ, in 1993.

FMC-6 possesses significantly better turf quality than Arizona Common, and ‘NuMex Sahara’. This is due to shorter leaf length, narrower leaf width, shorter plant height, slower vertical elongation rate, and a greater level of cold tolerance for FMC-6 than Arizona Common and NuMex Sahara (Baltensperger et al., 1998; Morris, 1997). FMC-6 possesses significantly greater turf density, darker green color, and greater bermudagrass stunt mite resistance compared to Arizona Common (Morris, 1997). FMC-6 has shown good adaptation on low pH soils (pH 3.6- 4.5) relative to other seeded bermudagrasses (Morris, 1997). FMC-6 has the potential for excellent turf performance in home lawns, parks, athletic fields, and golf courses in areas where bermudagrass is adapted.

Seed production is limited to two generations of increase beyond Breeder seed: Foundation and Certified. All classes of seed stock are maintained by Pennington Seed/Seeds West (37860 W. Smith-Enke Rd, Maricopa, AZ 85365). FMC-6 is available as Certified seed and is sold under the name Sultan_Brand from Pennington Seed/Seeds West. U.S. Plant Variety Protection for FMC-6 has been granted (PVP Certificate No. 9500020).
