Abstract:
Most commercial apple cultivars have high to medium chilling requirements and consequently are not grown in regions with warm winters. Furthermore, global climate changes raise the concern that some regions where apples are currently being produced will become unsuitable in the future. Therefore, mapping and understanding the factors governing chilling requirements are important goals towards the breeding of new apple varieties. In this study, we characterized 73 apple accessions: old local accessions, modern cultivars, and selected hybrids, all grown in the Newe Ya’ar germplasm collection in Israel under moderate winter conditions. We measured the time of vegetative bud-break as an indicator of chilling requirements and genotyped the accessions for known genetic markers and for markers we developed by re-sequencing the genome of ‘Anna’, a cultivar with very low chilling requirements. Our results show that while most of the accessions that were characterized as having early bud-break are genetically different from each other, they all share a unique haplotype in a region of ∼190 kb, within a previously identified QTL for bud-break time, on chromosome 9. The alleles in the early bud-break-associated haplotype were not found in any of the late accessions tested, suggesting that the causative difference leading to the variation in bud-break time lays within or near this region, and that there is a common ancestor carrying early bud-break trait of the early accessions tested. Moreover, the markers of the unique haplotype can serve as genetic markers to accelerate the breeding of apple cultivars better adapted to warm climates. © 2016, Springer Science+Business Media Dordrecht.
