Abstract/Contents: | "Tillers and rhizomes are important physiological feature for turfgrasses, and thus 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. Tillers and rhizomes are also thought to be helpful for sod production. Kentucky bluegrass has the ability to form rhizomes, and is the predominant sod species in Minnesota and the surrounding states; 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 ssp. 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. A total of 192 accessions were each represented by single genotypes in each of the four replications; we also included check cultivars of Kentucky bluegrass, strong creeping red fescue, hard fescue, and Chewings fescue. One-month-old plants, started from seed, were grown under Minnesota summer conditions for three months. Non-destructive aboveground phenotypic data was taken every two weeks for vertical growth, tillering, and daughter plant production. After three months, destructive phenotypic data was taken to quantify and characterize belowground rhizomatous growth. The panel revealed high variation in the measured traits. Tiller number ranged from 2 to 115, and rhizome number ranged from 0 to 23. The majority of accessions were capable of rhizome formation, which appeared to accelerate in the final month of the study. This diversity should be useful for turfgrass breeders in the development of new cultivars of fine fescue for use in sod production systems." |
