This feature has special appeal in subtropical and tropical regions (deep South regions of the United States) where chilling (dormancy) of Bermudagrass is borderline. MS-Pride's better than average fall color retention makes it highly desirable in these regions.
The unmowed height and sod strength of MS-Pride was measured at 1 location for 1 year and 1 location for 2 years, respectively (Table 11). MS-Pride had a low unmowed height and better than average sod strength compared to the other Bermudagrasses tested.
The low temperature kill of MS-Pride was measured at 1 location for 2 consecutive years (Table 12). During both years, MS-Pride had only moderate low temperature kill compared to the other Bermudagrasses tested.
