| Abstract/Contents: | "In April, 1984, the Texas Agricultural Experiment Station, Bentgrass Research, Inc., and the United States Golf Association embarked upon a joint endeavor to develop bentgrases which are genetically adapted to environmental conditions in the southern United States. The germplasm collection currently includes over 520 vegetative accessions, 168 seeded accessions, 300 'Seaside" selections, and ten commercial or experimental varieties. Facility development to accommodate testing of this material has continued, with Bentgrass Research, Inc. constructing a new 1610 sp. meters [17,000 sp. ft.] sand base research green, with completion expected by November 1, 1986. Field, laboratory and greenhouse experiments are progressing toward identification of superior genotypes. Testing is currently in progress in a greenhouse heat bench to determine sensitivity of seven cultivars and two experimental varieties to heat stress. Initial results indicate differences do exist between genotypes. Characterization of root systems to identify plants which will avoid heat-induced drought stress continues. Forty-seven Seaside and Seaside-RHT plants have been screened, with fifty additional clones under current evaluation. Completed evaluations indicate differences exist between genotypes. A manuscript summarizing the results from the first evaluation was submitted to the Texas Turfgrass Research Report - 1986. Preliminary laboratory evaluations to determine if selection for root heat tolerance has influenced shoot heat tolerance indicate significant differences in shoot hydration exists between genotypes when grown under stress. Field testing under both native blackland soils and root zone modified 'USGA sand based greens' conditions continue. Two-hundred thirty elite vegetative accessions were planted on blackland soil during May 1986, with turf quality ratings indicating approximately 25% of these express superior adaptive characters. In addition, approximately 25% of the ELITE genotypes planted on sand base green performed in a superior manner during 1986. Two-hundred ninety-four plants of Seaside and Seaside-RHT were planted during April 1986. Periodic evaluations indicated tremendous genotypic differences in spread, texture, density, color and overall quality, with 46 clones ranging in the top quality group. Selection for root heat tolerance has not adversely affected the quality characters evaluated. A project contract was established in 1985/86 with Dr. Jerry Pepin, and Pickseed West, Inc., Tangent, Oregon, to assist the breeding program in seed production of elite and synthetic germplasm resources. Floral initiation and development did not occur in the field plantings at Dallas during 1986, but was successful in Oregon. The plantings of elite germplasm in Oregon determined cross-compatibility dates for the genotypes, and generated sufficient seed quantities for advanced generation testing. Three synthetics have been composed and have been transferred to Oregon for 1986/87 production." |
