Narrative
‘MS8-264’ and ‘MSB-285’ are fine-textured, high-quality interspecific bermudagrasses (Cynodon dactylon × C. transvaalensis) developed at Mississippi State University. These two grasses were released on 25 August 2021 from Mississippi Agricultural and Forestry Experiment Station. Compared to Tifgreen-derived bermudagrass cultivars, ‘MSB-264’ and ‘MSB-285’ were bred from a much different genetic background with no mutations involved. Both ‘MSB-264’ and ‘MSB-285’ are different from and morphologically advantageous compared to other bermudagrass cultivars. Through the 2013 National Turfgrass Evaluation Program warm-season putting green test, data were collected for four years across 11 locations in the U.S. Compared to the commercial cultivars (‘Sunday’, ‘TifEagle’, ‘TifDwarf’, and ‘Mini-Verde’) and other experimental lines, both ‘MSB-264’ and ‘MSB-285’ exhibited superior turf quality, leaf texture, density, genetic color, fall and winter color retention, spring-greenup speed, and percent ground living cover. ‘MSB-264’ and ‘MSB-285’ also have a more upright leaf orientation than traditional bermudagrass putting green cultivars. Growth habit of these two varieties is more similar to that of creeping bentgrass (Agrostis stolonifera), a species that provides a highly desirable golf putting surface in cooler climates. Distinct genetic background and positive performance data demonstrated the novelty of these two bermudagrass cultivars. Although ‘MSB-264’ and ‘MSB-285’ had higher seedhead production compared to the commercial cultivars and other experimental lines, regular mowing could effectively remove seedheads.

Pedigree
Description:
Bermudagrasses ‘MSB-264’ and ‘MSB-285’ are new and distinct bermudagrass varieties developed at Mississippi State University, Starkville, MS. ‘MSB-264’ and ‘MSB-285’ originated from a cross between Cynodon dactylon ‘MSB 28-18’, a very fine-leafed low-growing tetraploid (2n=4x=36), and C. transvaalensis genotype labeled ‘trans1’ (2n=2x=18). Accordingly, ‘MSB-264’ and ‘MSB-285’ are full siblings, sterile triploids (2n=3x=27) and do not produce seed. Cross pollination was performed in May 2003 at Starkville, Mississippi. Seeds from the cross were germinated in January 2004 in a controlled-temperature chamber. The seedlings were then individually transplanted to a greenhouse. ‘MSB-264’ and ‘MSB-285’ have been vegetatively propagated since germination.
