“…In order to reach a high reproducibility, experiments under controlled conditions were developed to analyse frost tolerance. In several crop species, frost tolerance was found to be a main component of winter-hardiness (Rizza et al 1994;Petcu and Terbea 1995;Arbaoui et al 2008). The frost tolerance of a plant was defined as (1) its unhardened frost tolerance and (2) its hardening response.…”

In faba bean, field based winter-hardiness is a complex trait that is significantly correlated to frost tolerance. Frost tolerance could be used to indirectly select for faba bean winter-hardiness. The aim of this study was to identify putative QTL associated with frost tolerance and auxiliary traits and to quantify the efficiency of marker assisted selection. Thus, 101 recombinant inbred lines derived from the cross between two frost tolerant lines were tested for their hardened and unhardened frost tolerance and for their leaf fatty acid content in both treatments. Significant differences among the RIL were observed for all studied traits. For frost tolerance, five putative QTL were detected; three for unhardened frost tolerance that explained 40.7% (8.6% after crossvalidation, CV) of its genotypic variance and two for hardened frost tolerance that explained 21.8% (1.0% after CV). For fatty acid content, three QTL were detected for oleic acid content in unhardened leaves that explained 62.9% (40.6% after CV) of its genotypic variance. This fatty acid was significantly correlated with unhardened frost tolerance. The unbiased genotypic variance explained enabled to draw realistic prospects of MAS for frost tolerance. In this study, combined MAS was more efficient than classical phenotypic selection and was expected to be higher on larger populations at early generations. Moreover, favourable alleles inherited from the exotic line BPL 4628 could be introgressed to European winter-hardy beans for further improvement.

“…Recent studies in faba bean showed that polyunsaturated fatty acid accumulation were adaptation mechanisms to low non-freezing temperatures, but also significant correlated traits to frost tolerance (Arbaoui et al 2008).…”

“…With the advent of climate change and some improvement of freezing resistance and general winter hardiness (Arbaoui et al 2008a), the zone of adaptation of winter faba bean is expected to expand to more continental regions in Europe.…”

“…Accumulation of cryoprotectants such as proline during hardening was shown to be correlated with freezing resistance (Arbaoui et al 2008a). The role of glycinebetaine, which similar to proline is a cytoplamic osmoticum in several higher plant families, is unclear.…”

“…To analyze freezing resistance, assessments may be made of freezing-induced electrolyte leakage (Herzog 1987), chlorophyll fluorescence (Taulavuori et al 2000), or accumulation of proline, of certain sugars or of membranebound polyunsaturated fatty acids (Arbaoui et al 2008a). Quantitative Trait Loci (QTL) have been developed for freezing resistance and related traits in faba bean (Arbaoui and Link 2008) and also in the model legume Medicago truncatula (Avia and Lejeune-Hénaut 2007).…”
