Abstract/Contents:"Tillers and rhizomes are important physiological features for turfgrasses, and may be traits deserving of more focus for cool-season turfgrass breeding. These two types of stems can allow for resilience and competitiveness in a lawn, and are thought to be helpful for sod production. Kentucky bluegrass is the predominant sod species in the Midwest and other cool-season areas; however, consumers would benefit from increased availability of fine fescue sod for lawns, roadsides, and other areas where low-input species would be useful. Strong creeping red fescue (Festuca rubra subsp. rubra) displays robust rhizomatous growth that parallels Kentucky bluegrass. The investigation of tillering and rhizome traits of this fine fescue species could help plant breeders develop new cultivars with enhanced sod forming ability. The objective of this project was to quantify tiller and rhizome production in a diverse set of strong creeping red fescue germplasm in a mowed spaced plant setting, including cultivars, breeding material, and unimproved collected germplasm. 254 entries that passed a minimum threshold for strong creeping red fescue DNA content were represented by a clone of a single genotype each in four blocks. We also included check cultivars of Kentucky bluegrass, slender creeping red fescue, hard fescue, and Chewings fescue. Plant plugs were grown in the greenhouse and transplanted to the field in fall 2020. Non-destructive aboveground phenotypic data was taken in November 2020 and every two months of the 2021 growing season for horizontal growth and daughter plant production. At the end of the season, destructive phenotypic data will be taken to quantify and characterize belowground rhizomatous growth. This study complements previous growth chamber studies of collected germplasm which revealed high variation in the measured traits. This diversity should be useful for breeders in the development of new cultivars of fine fescue for use in sod production systems."
