| Abstract/Contents: | "Rutgers University and USDA-ARS scientists continue to unravel the genetics of creeping bentgrass drought and heat tolerance. To date, findings of this research include: Significant phenotypic variations in drought or heat tolerance were found in two populations of bentgrass species segregated for disease resistance. Phenotypic variations in drought and heat tolerance in both the creeping bentgrass and creeping and colonial bentgrass hybrid populations allowed for identification of potentially important QTL regions for drought and heat tolerance. Major QTLs were found in several chromosomal regions which were consistent across years and environments, such as mapping groups 5 and 11 for the bentgrass population and chromosomes 2A1 and 2A2 for the colonial/ creeping bentgrass hybrid backcross population. These may be important chromosomal regions with QTL markers governing stress tolerance traits in bentgrass species. Regions of mapping 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 most useful in future studies for development of marker-assisted selection of both drought- and heat-tolerant creeping bentgrass cultivars." |
