| Abstract/Contents: | "Susceptibility to heat stress limits use of bentgrass for high quality playing surfaces in the Southern and Central United States. In the fall of 1981, a group of individuals in the north Texas area interested in bentgrass established a fund-raising organization named Bentgrass Research, Inc., to support bentgrass research at TAES-Dallas. In October 1982, a 3600 square foot sand green was constructed by this group for research purposes. In April 1984, the United States Golf Association joined in a concerted effort for the "Breeding and Development of Bentgrass". A limited collection of bentgrass germplasm had been assembled at TAES-Dallas over the previous 4 years. Most notably were individual plants which had survived naturally under Southern climatic extremes, often in direct competition with other species such as bermudagrass. In total as of November 1985, over 200 vegetative accessions from two countries and five states, 129 seeded accessions from nine countries, and five commercial varieties were included in the collection. Since the initiation of this program, replicated plantings of most of the elite germplasm has been made to both the sand base green (96 elite clones) and to native blackland soil (230 vegetative accessions). These test sites will provide the initial field performance evaluations under greens and simulated fairway conditions over the next 18 to 24 months. Superior clones will be utilized in specific crosses to create new plants with desirable combinations of traits. In the spring of 1985, a specialized greenhouse heat bench was utilized to select 196 clones with heat tolerance from a population of approximately 20,000 plants of 'Seaside' bentgrass. A root growth characterization study was initiated in mid-summer 1985 to examine the inherent genetic variation within the germplasm pool and to identify unique rooting characters which may be associated with plants selected for heat tolerance from the heat bench. Twenty clones were randomly selected from the elite vegetative material and included with 25 clones from the heat tolerant POPULATION A selections and from the base population of Seaside. Research planned for 1986 includes planting and evaluation of the selected heat tolerant bentgrasses for agronomic quality on a sand base green. Using a temperature controlled water bath system, experiments are planned to correlate the tissue tolerance and root tolerance to high temperatures between the unselected base population of bentgrasses and those selected for heat tolerance. Utilizing the specialized heat bench, comparisons are planned to determine the relative heat tolerance of commercial bentgrass varieties. Heat susceptible and heat tolerant genotypes will be examined morphologically to identify characters which may be associated with the mechanism of biological heat tolerance." |
