| Abstract/Contents: | "The extensive use of nitrogen (N) fertilizer can be one of the major factors that may contribute to increased investment in turfgrass management. The use of N-efficient turf cultivars is an important strategy for integrated turf nutrient management in both low- and high-input turf fields. The objective of this study was to identify genes significantly associated with leaf N use in perennial ryegrass germplasm. One hundred and ninety two diverse perennial ryegrass accessions were screened for N use under normal N (7.5 mM) and low N (0.75 mM) for 3 weeks. Significant variations of leaf dry weight, chlorophyll index, chlorophyll fluorescence, leaf N use were found among accessions. Large amount of genome-wide single nucleotide polymorphism markers were obtained using genotype-by-sequencing. Associations of genome-wide markers with N use traits are being analyzed. The results would benefit the creation of turfgrass cultivars with improved N use." |
