Abstract/Contents:Presents a study initiated during 2008 to identify quantitative trait loci (QTL) related to the drought and heat tolerances of creeping bentgrass. Notes that primary objectives of the study are to "(1) evaluate variations in drought and heat tolerance for two mapping populations of bentgrass segregating for disease resistance," "(2) identify phenotypic traits associated with drought and heat tolerance," and "(3) identify QTL markers associated with drought and heat tolerance utilizing the available linkage maps." Details methods and materials used during the study, stating that "turf quality (TQ) was rated visually based on a scale of 1-9 (1 = dessicated, brown; 9 = healthy, green)." Reports that "QTL regions that were consistent across years and environments...may be important chromosomal regions governing stress tolerance traits." Concludes that "regions of chromosomes groups 3 and 11 in the creeping population were significant for both heat and drought tolerance."

USGA Summary Points:Phenotypic variation in drought and heat tolerance in both the creeping and hybrid bentgrass populations allowed for identification of potentially important QTL regions QTL regions that were consistent across years and environments such as group 5 and 11 for the bentgrass population and 5 and 10 for the hybrid population may be important chromosomal regions governing stress tolerance traits Regions of chromosomes groups 3 and 11 in the creeping population were significant for both heat and drought tolerance. The importance of these groups in tolerance to multiple stresses may be the most useful in future studies for development of marker-assisted selection procedures
