| Abstract/Contents: | "Research efforts in 1994 have been focused on developing a valid, quantifiable procedure at the whole plant level to verify resistance to Rhizoctonia solani exhibited by HPIS derived creeping bentgrass variants. Several studies were conducted to address inoculation techniques, optimum environmental factors for disease, and evaluating pathogenicity of R. solani isolates. Four creeping bentgrass lines have been identified with enhanced resistance to R. solani. This study was conducted using HPIS derived bentgrass variants maintained in pots (7 cm dia) in an environment controlled greenhouse. Under ideal environmental disease conditions for brown patch, HPIS variants were inoculated with a highly pathogenic isolate of R. solani. Average diameter of disease turf (mm) for lines displaying enhanced resistance were 21.6, 25, 27.5, and 28.3. These values represent a significant improvement compared to Penncross with an average 50.0 mm of diseased turf. This phase of research has shown that the Host-Pathogen Interaction System is a valid in vitro cell selection technique for selecting creeping bentgrass germplasm with enhanced resistance to Rhizoctonia solani. Prior to field evaluations, selected creeping bentgrass lines have undergone three levels of exposure to R. solani. A cycle for the selecting germplasm with enhanced resistant [resistance] has been accomplished beginning at the cellular level, affirmed at the plantlet level (in vitro), and confirmed at the whole plant level. Selected lines will be evaluated in the field under golf course conditions. As additional resistant lines are obtained they too will be included in field evaluations. Continued progress in this research project will lead to parental lines of creeping bentgrass that exhibit enhanced resistance to Rhizoctonia solani, the causal organism of brown patch." |
