MS-Express's origin may be from anyone of the following sources: (a) a seed within the original seed lot; (b) a seed or plant introduced unintentionally to this site; or (c) a plant which developed as a result of an environmentally selected mutations.
The identifying features of the original clone of MS-Express were a medium green color, very fine leaf texture, prostrate leaf growth, and a high shoot density. The size of the original clone was approximately 2 ft in diameter. A 4 inch diameter plug was removed from the center of the clone and transplanted to a Bermudagrass nursery located at the Plant Science Research Center. MS-Express was 1 to 72 ecotypes of Bermudagrass planted and maintained in this nursery.
MS-Express was evaluated for 5 years in this nursery. During this period, MS-Express maintained its original green color, very fine leaf texture, prostrate growth of leaves, and high shoot density.
In 1986, MS-Express was included in a regional Bermudagrass evaluation trial located at 15 sites encompassing 11 states. Data was collected from 1986 to 1990. The findings from this study confirmed MS-Express's light to medium green color, prostrate leaf growth, and high shoot density.

The seed head density of MS-Express was measured at 3 location for 2 or 3 years depending on location (Table 2). At all three locations, MS-Express had slightly higher than average seed head density compared to the other Bermudagrasses tested.
The genetic color of MS-Express was visually rated at 7 locations for 1 or 2 years depending on location (Table 3). At all locations, MS-Express's color was rated light to medium green. The stolons are light green and rhizomes are white.
The color designation of MS-Express is 7.5 GY 5/8 using a Munsell color chart rating.
The shoot density of MS-Express was measured at 2 location for 1 or 2 years depending on location (Table 4). MS-Express has a high shoot density that ranked average or slightly higher compared to the other Bermudagrasses tested.
The shade tolerance of MS-Express was measured at 1 location for 2 years (Table 5). MS-Express has a good tolerance to shade that ranked above average compared to the other Bermudagrasses tested.
MS-Express's ploidy level and chromosome number were determined and compared to other Bermudagrasses (Table 6). MS-Express was found to be a triploid with 27 chromosomes.
The overall turf quality of MS-Express was measured at 15 locations for 1, 2, or 3 years depending on location (Table 7). MS-Express has excellent turfgrass quality. In comparison to other Bermudagrasses tested, MS-Expressed at or near the top of the rankings depending on location.
Leaf texture based on a visual comparison was measured at 8 locations for 1 or 2 years depending on location (Table 8). MS-Express has a fine leaf texture that ranked well above average when compared to the other Bermudagrasses tested.
The establishment rate of MS-Express was measured at 6 locations during the 1986 establishment year (Table 9). MS-Express had the highest establishment rate 4 to 5 weeks after planting compared to the other Bermudagrasses tested.
Fall color retention of MS-Express was measured during the month of November at 6 locations for 1 or 3 years depending on location (Table 10). MS-Express had good fall color retention that ranked at or slightly less than average when compared to other the other Bermudagrasses tested.
The unmowed height and sod strength of MS-Express was measured at 1 location for 1 year and 1 location for 2 years, respectively (Table 11). MS-Express had a low unmowed height and average sod strength compared to the other Bermudagrasses tested.
The low temperature kill of MS-Express was measured at 1 location for 2 consecutive years (Table 12). During both years, MS-Express showed better than average low temperature tolerance compared to the other Bermudagrasses tested.
MS-Express's resistance to leafspot (Helminthosporium spp.) and dollar spot (Sclerotinia spp.) was measured at 1 location for 2 years (Table 13). MS-Express showed good resistance to leafspot and slightly above average susceptibility to dollar spot compared to other Bermudagrasses tested.
MS-Express can be distinguished by morphological and turf performance characteristics. MS-Express has high turf density and quality as illustrated in pot and field plot culture (FIG. 1 and 2). MS-Express's shoot structure is pilose on the abaxial and adaxial leaf blade surfaces, pubescence tufted at the ligule margins, and glabrous on the adaxial leaf surface and sheath (FIG. 4).

Length of an average spikelet is 2.30 mm with glumes extending 1/3 to 1/2 the length of a floret (FIG. 5 and 6). The flower of MS-Express has a purple stigma and yellow anthers.
MS-Express has a narrower leaf than MS-Choice and Midiron, but a wider leaf width than MS-Pride, Tifgreen, Tifway II, and Tifway (Table 1). Leaf length of MS-Express is shorter than Midiron and Tufcote. There were no difference in internode length between MS-Express and the other Bermudagrasses tested. The internode and node diameters of MS-Express were larger than MS-Pride, Tifway II, and Tifway, but smaller than MS-Choice and Texturf 10. Seed head density of MS-Express was higher than MS-Choice, Tifway, Tifway II, Texturf 10, Tufcote, Midiron, and MS-Pride (Table 2).
MS-Express has turf performance characteristics that distinguish it from other Bermudagrasses. Compared to other fine textured Bermudgrasses, MS-Express has a significantly faster rate of establishment (Table 9).
