| Abstract/Contents: | "Seeded Releases: Seed West has elected to leave the Native Turf Group (NTG). This was over a decision on who would market the new release NTG-5. NTG-7 and FW-3 are being evaluated at the John Seaton Anderson Turfgrass and Ornamental Research Facility. Charlie Rodgers of Seeds West has indicated that they would still like to market NTG-5. Terry Riordan is encouraging Seeds West and NTG to do this. It would mean $ 10,000 in royalties to the USGA. Vegetative Released: Patents have been approved for released Ne 86-61, NE 86-120, and Ne 91-118. Publication of the crop registration should occur this winter in the Crop Science Journal. Ne 86-61 has been named 'Legacy' and 35 acres are being produced by Todd Valley Farms at Mead, Ne. Legacy will be available in the northern United States next year. Crenshaw Turf, Inc. Update: Crenshaw Turf is now part of Turfgrass America, Inc. along with Thomas Bros. Sod and Milberger Turf. Their goal is to be the premiere supplier of proprietary southern turfgrasses, ie. bermudagrass, zoysiagrass, St. Augustinegrass, and buffalograss. This would include genetically enhanced turfgrasses. Sales of buffalograss for 1999 are down, but they have indicated that is more due to reorganization of the companies than lock of interest in buffalograss. Summary of Breeding Work: Performance levels continued to improve with the establishment of a new breeding nursery in 1999. Numerous accessions in this nursery have exhibited increased establishment rate over commercially available cultivars. newly released cultivars continue to show their superiority over older varieties with improved sod strength, color, turfgrass quality, and density. The establishment of six new crossing blocks in 1999 with selections exhibiting fairway type characteristics should provide germplasm with higher levels of turf quality and adaption to golf course management systems. Seed Production: Buffalograss seed production has received major attention in 1999. To insure the successful use of buffalograss, seed production characteristics must be a major factor in the selection process. The buffalograss project initiated a three-phase approach to provide high turf quality varieties with high seed yields. Phase one involves breeding of high yielding female lines with advanced male accessions that contribute to seed yield, seedling vigor, and turf performance characteristics. The second phase is the use of fly cytometry to identify crossing accessions of similar Ploidy levels. The third phase is to explore chemical applications of plant hormones to enhance seed production. Sprig Establishment: Establishment of buffalograss has always been a major objective of the project. Great strides have been made with buffalograss establishment since the project was first initiated. Initial studies in the 1980's indicated that pre-rooted plugs had an advantage in establishment over seeded varieties. These improvements are due to improved selections that exhibit quicker germination and improved seedling vigor, and because of better production of seed by producers. Sprigging of buffalograss has also shown potential to provide very rapid establishment rates. The research project will focus on improving sprigging characteristics in addition to seed production. Fertility and Mowing Effects on Buffalograss: At the Nebraska site, NE 91-118 and 378 had the highest quality ratings at the 2.5 cm mowing heights for years 1996-1998. Cody and Texoka had poor quality ratings at the 2.5 cm mowing height for all years. In 1998, NE 91-118, 378, and Cody had the highest quality ratings at the 5.1 cm mowing height. At the 7.6 cm mowing height Cody and Texoka had the highest quality rating in 1997 but Cody and 378 had the highest quality ratings in 1998. From 1997 to 1998 several trends are evident. First, turfgrass quality decreased from 1997 to 1998 for cultivars at the o, 2.4, and 5.0 g N m-2 rates. At 10 g N m-2, NE 91-118 and 378 had higher quality in 1998 than in 1997. All cultivars had improved quality ratings in 1998 at the 20 g N m-2 rate. Quality ratings in 1998 were poor (ie. <6) for all cultivars at 0, 2.4, and 5.0 g N m-2 rates. At 10 g N m-2 NE 91-118, 378, and Cody had good turfgrass quality. Management recommendations for 378 and NE 810118 are 2.5 or 5.1 cm mowing heights and a nitrogen rate of 10 g N m-2 year1. Recommendations for Cody and Texoka are 5.1 or 7.6 cm mowing heights and a nitrogen rate of 10 g N m-2 year1. Buffalograss Resistance to Chinch Bugs: The development of turfgrasses with resistance to insects offers an attractive approach for managing insect pests associated with buffalograss because it is sustainable, environmentally-responsible, and fits well with buffalograss' low maintenance, reduced pesticide input philosophy. Greenhouse experiments were conducted to determine the categories of resistance of 10 buffalograss cultivars/selections ('Cody', 'Tatanka', '609', '315', 'Texoka', NE94-45-3, NE91-118, NE86-120, ME86-61) screened previously for resistance to the chinch bug, Blissus occiduus. From these initial greenhouse screenings, 'Cody', 'Tatanka', and NE91-118 were selected as resistant to B. occiduus and NE85-45-2 and '378' as susceptible. Although these three selections have been identified as chinch bug resistant, further evaluation is needed to determine the categories of their resistance (antixenosis, antibiosis, and/or tolerance)" |
