Abstract/Contents: | "Genetic resistance to dollar spot disease incited by Sclerotinia homoeocarpa F.T. Bennett is a promising component of sound integrated disease management programs. Previous research indicates that dollar spot resistance is quantitatively inherited with no evidence of major disease resistance genes; however, the response of creeping bentgrass genotypes to different isolates has not been evaluated. The objectives of this study were to evaluate the response of creeping bentgrass crosses to three different isolates of S. homoeocarpa, evaluate disease progression, determine gene action, and identify number of loci involved in resistance to individual fungal isolates. Four hundred plants of each of three reciprocal controlled crosses were established in a field trial in a randomized complete block design in the fall of 2000 and 2002. Eight backcross and four F2 populations were also included in the 2002 trial. One hundred progeny of each cross were inoculated with one of three isolates of S. homoeocarpa, and a mixture of the three isolates and evaluated for dollar spot disease. The degree of dollar spot disease differed depending on the cross and the isolate evaluated. Backcross populations were skewed towards the recurrent parent regardless of resistance or susceptibility. Minimum loci calculations differed depending on the cross and the isolate. These results indicate the presence of different genes associated with resistance and susceptibility depending on grass genotype and fungal isolate." |
