| Abstract/Contents: | "Primary emphases in the initiation of the program included assessment of existing plant materials (germplasm) and acquisition of additional plants to increase the germplasm base. Existing material came primarily from New England. Additional plants were obtained from the New Zealand collections of Dr. William Rumball and collection trips from Maine to Pennsylvania and all states in between except Vermont. Much area remains to be covered, including collections further south along the East Coast of the United States where higher humidity and heat conditions may be more favorable for obtaining brown patch resistant colonial bentgrasses. The area of origin, Europe, needs to be explored as well. Ms. Pei-Yu Zeng, an M.S. degree student, officially began working with this project this fall. Her thesis will concentrate on Rhizoctonia sp. (brown patch) resistance screening in bentgrasses. Cooperative collection efforts with private industry are forging associations which will enhance cultivar distribution of improved materials. One association has already produced progeny from 69 initial collections which have been planted for turf trial evaluation this fall in Rhode Island. Greenhouse facilities were greatly expanded with the addition of approximately 1000 square foot polyhouse almost exclusively used for the turfgrass improvement program. This has facilitated the ability to increase plantings from seed or vegetative plant parts for field and greenhouse evaluations. One of the most severe droughts in the region occurred this summer. Non-irrigated space plantings of the original bentgrass collection were examined for drought tolerance. Selections were grouped into one of three categories: low, medium, or high drought resistance. One group of each classification, containing three to five parents each, was established in a polycross nursery for seed production next spring. Progeny will be evaluated for brown patch resistance and potential association to drought resistance. Six isolates of Rhizoctonia sp. are in increase incubation for inoculating greenhouse materials in November and December. Initial molecular identification screening was difficult due to contamination in field plots. Additional support was provided by the University of Rhode Island Faculty Development Program, the USDA, the New England Golf Course Superintendents' Association, private turf industries, plant royalties, the state of Rhode Island, and Federal Hatch funding." |
