Association of candidate genes with traits of perennial ryegrass assessed by using a population structure controlled model (Q model).
| Trait | Putative Gene | Locus | R 2_Marker | P_Marker |
|---|---|---|---|---|
| D-Fv/Fm | LpCyt Cu-ZnSOD | 134 | 0.0969 | 9.02E-05 |
| D-Fv/Fm | LpCyt Cu-ZnSOD | 220 | 0.0828 | 2.48E-04 |
| D-Fv/Fm | LpCyt Cu-ZnSOD | 287 | 0.0752 | 4.94E-04 |
| D-LWC | LpLEA3 | 285 | 0.0905 | 3.92E-04 |
| D-LWC | LpLEA3 | 237 | 0.0914 | 3.63E-04 |
| D-LWC | LpLEA3 | 77 | 0.0625 | 0.0048a |
| D-LWC | LpFeSOD | 411 | 0.0945 | 2.63E-04 |
a Locus 77 was included for further analysis due to its significant association under the P < 0.01 level and linkage disequilibrium with locus 237 and 285.
D-Fv/Fm, chlorophyll fluorescence under drought conditions; D-LWC, leaf water content under drought conditions.
