| Abstract/Contents: | "Perennial ryegrass (Lolium perenne L.) susceptibility to winterkill limits its cultivation at northern latitudes while freezing tolerance is seen as a major target for winter hardiness improvement. Field winter survival (FWS) was evaluated in perennial ryegrass association mapping population of 210 genotypes. FWS revealed significant (p < 0.0001) differences between ecotype and cultivar subgroups of the population. A subset of 76 genotypes was further tested for freezing tolerance parameters under controlled-environment conditions. Mean percentage of tiller survival (PTS) in controlled-environment experiment was 53.05 % ± 3.58 % and 9.99 % ±2.01 % at - 8 ° C and - 12 ° C, respectively. Proline content (PC) ranged from 0.47 to 6.15 mg g-1 dry weight (DW), while electrolyte leakage (EL) varied from 6.09 to 25.80 % at - 8 ° C and from 22.27 to 63.51 % at - 12 ° C. Correlations between PTS and EL were moderate negative but significant (p < 0.001) at tested temperatures. No correlation between PC and PTS was detected. Variation for freezing tolerance parameters and minimum kinship indicate the suitability of the population for association mapping of freezing tolerance related traits, although a model that accounts for population structure is required." |
