Registration of 'MS-Express' bermudagrass.
MS-Express is an improved triploid (2n = 3x = 27) turf-type bermudagrass (Cynodon ×magenissii) cultivar (PI584767) released in 1991. It was derived via selection in a collection of 72 ecotypes collected from non-irrigated fairways of 4 golf courses in west-central Mississippi during a period of prolonged drought. When evaluated in the National Bermudagrass Test in 1986 under the experimental designation MSB20, MS-Express displayed medium-green colour, good spring green-up, fine leaf texture, high density and rapid establishment. In 21 evaluations that included sites in 13 states, MS-Express ranked fourth in overall turfgrass quality among the 28 cultivars studied. Under medium levels of disease incidence, MS-Express exhibited good resistance to Bipolaris cynodontis [Cochliobolus cynodontis] and dollar spot (Lanzia and Moellerodiscus spp.). MS-Express has good shade tolerance compared with other bermudagrasses, but poor frost tolerance. MS-Express must be vegetatively propagated. It is recommended for putting and bowling greens, and tennis courts, in regions where bermudagrass in adapted for turf.
