| Abstract/Contents: | "Bermudagrass (Cynodon spp.) and seashore paspalum (Paspalum vaginatum) are commonly used warm-season turf grasses on golf courses in Florida. Belonolaimus longicaudatus is the most serious nematode pest on turf grass in Florida. Recent cancellation of fenamiphos has resulted in the need for alternative nematode management tactics. Utilization of resistant or tolerant cultivars is the most efficient and least costly practice for nematode management on turf, but information about the responses of most grass cultivars to B. longicaudatus is not available. The objective of this study is to evaluate newer turfgrass cultivars for resistance and tolerance to B. longicaudatus and to select Cynodon spp. germpalsm [germplasm] accessions with superior nematode responses that can be used in future cultivar breeding and development. Three experiments were conducted to test 17 bermudagrass cultivars, seven seashore paspalum cultivars, and 47 bermudagrass germpalsm [germplasm] accessions, respectively in two sequential trials in a greenhouse in 2009. Aerial stolons were grown in sand-filled plastic containers and inoculated with 0 or 50 B. longicaudatus per conetainer [container] six weeks after planting. Turf was maintained in a randomized complete block with six replications. Nematode and root samples were collected 90 days after nematode inoculation. Both trials showed that among the dwarf bermudagrass cultivars, 'Tifdwarf' and 'Emeraldwarf' were tolerant, but susceptible to B. longicaudatus; 'Champion', 'Tifeagle', and 'Floradwarf' were resistant, but intolerant to B. longicaudatus. The non-dwarf bermudagrass cultivars, 'Tifsport', 'Patriot', and 'Riviera' were both tolerant and resistant to B longicaudatus. The non-dwarf bermudagrass cultivar 'Princess 77' was the most susceptible bermudagrass with nematode reproductive factor of 5.5. All seashore paspalum cultivars supported the reproduction of B. longicaudatus. Highest and lowest population densities were on 'SeaIsle 2000' and 'Aloha', respectively. The root length of 'SeaSpray' was reduced by B. longicaudatus. Four African bermudagrass accessions and nine common bermudagrass accessions were selected based on both tolerance and resistance to B. longicaudatus for future turf breeding. The development and use of resistant or tolerant cultivars could produce high quality turf grass while reducing the use of nematicides, fertilizers, and water. These cultivars also can be used as standards for future germplasm accessions screening and testing of newly developed cultivars." |
