Abstract

Registration of 'MS-Choice' bermudagrass.

Abstract

Released in 1991, this improved turf-type Cynodon dactylon cultivar (PI584769) was developed on the basis of selection for high shoot density, dark-green colour and low seedhead density in 72 ecotypes collected from non-irrigated fairways of 4 golf courses in west-central Mississippi during a prolonged period of drought. It is a tetraploid (2n = 4x = 36). MS-Choice was evaluated in the National Bermudagrass Test in 1986 under the experimental designation MSB30. It displayed dark-green colour, medium leaf texture, medium rate of establishment, and high shoot density relative to other tetraploid bermudagrasses. In 21 evaluations that included sites in 13 states, MS-Choice ranked 6th in overall turfgrass quality among the 28 cultivars tested. Under medium levels of disease incidence, MS-Choice exhibited good resistance to Bipolaris cynodontis [Cochliobolus cynodontis]. MS-Choice must be vegetatively propagated. It is recommended for lawns, sports fields, golf tees and fairways in regions where bermudagrass is adapted for turf.
