| Abstract/Contents: | "Association mapping provides a powerful tool for dissecting complex quantitative traits. Cold hardiness influences survival of perennial grasses in temperate regions. We conducted candidate gene association mapping of cold hardiness in 192 perennial ryegrass (Lolium Perenne L.) accessions. The population panel showed significant variations in phenotypic traits of percentage of winter recovery, chlorophyll index, and normalized difference vegetation index. Five population structures were found in the population assessed by 109 simple sequence repeat markers in perennial ryegrass. A total of 346 non-rare single nucleotide polymorphisms (SNPs) were discovered by sequencing 14 candidate genes involved in antioxidant metabolism, dehydration, and water movement across membrane and signal transduction. The model implementing population structure eliminated 90 % of false positive correlations, compared to simple linear model. Eleven significant associations between genes and traits were identified after controlling population structure. The results provide important information for further gene validation and genetic improvement for cold hardiness of perennial grasses." |
