| Abstract/Contents: | "Accessions continue to be added to the current germplasm collection. Four private companies have been actively involved with cooperative acquisition and assessment of materials introduced from this program. More than 600 plants were set in the field in fall 1993, including up to five clones of each accession. A cold, snowy winter and cold spring stressed young plants set in the field in late fall. Most survived the stress, despite their late establishment. These plants were evaluated for growth characteristics. Seed collection was not possible with most accessions in spring 1994. Additional material was propagated for greenhouse assessment and planting in the adjacent field plots in 1994. Ms. Pei-Yu Zeng, an M.S. degree student, conducted preliminary and advanced greenhouse screening trials for Rhizoctonia sp. (brown patch) resistance in bentgrasses. From a start of eight strains of this fungus, the three most virulent strains were determined for use in the larger screening of the entire germplasm collection later in the year. Differences among the fungal strains were confirmed by Polymerase Chain Reaction (PCR) technology. Cooperative collection efforts with private industry are forging associations which will enhance cultivar distribution of improved materials. Progeny from 69 initial collections planted for turf trial evaluation last fall in Rhode Island showed varied degrees of establishment and survival this spring, as well as possible resistance to weed invasion. The highest rated material has been planted in polycross this fall for seed production next spring in Oregon. This material was also included in the brown patch screening in Rhode Island. Molecular efforts have included successful preparation of both creeping and Colonial bentgrass in tissue culture suitable for gene transfer. We are currently trying to determine which genes are available and useful for this process. Additional support was provided by private turf industries, plant royalties, the State of Rhode Island, and Federal Hatch funding." |
