Special Issue Information

Dear Colleagues,

A recent estimate suggests that the world population will reach 9 billion or more by 2050, requiring a 70% increase or at least a doubling in food production. In addition, climate change is threatening to push the number of hungry even higher in the decades to come. Genetic diversity and plant breeding are key elements in tackling climate change. Advances in NGS technologies are providing the genetic basis of fruit tree species and allowing for the development of new strategies in breeding, such as genomic prediction; still, more research is required on these species to maximize crop productivity. For this Special Issue, we are interested in hearing your success stories from research in the genetics and genomics of fruit trees around the world. Submissions on the following (non-exclusive) topics are invited: (1) Discovery of genome-wide diversity through novel “omic” approaches; (2) Development of high-throughput genotyping tools; (3) Molecular dissection of complex traits; (4) Understanding of the G×E relationship, genotype by environment, to develop better statistical methods; (5) Production of easy-to-use data management and analytical protocols for routine applications.

Prunus species are important crops in temperate regions. In these regions, drought periods are predicted to occur more frequently due to climate change. In this sense, to reduce the impact of climate warming, obtaining new tolerant/resistant cultivars and rootstocks is a mandatory goal in Prunus breeding. Therefore, the current study assembled three Prunus species including almond, (P. dulcis Mill D.A. Webb), apricot (P. armeniaca L.) and peach (P. persica L.) to model the temporal effects of drought. A hybrid peach × almond and a wild almond-relative species Prunus webbii were also included in the study. Physiological traits associated with photosynthetic activity, leaf water status, and chlorophyll content were assessed under three watering treatments. Results showed that effects of time, genotype, and treatment interact significantly in all traits. In addition, results confirmed that P. webbii have a greater tolerance to drought than commercial rootstocks. However, “Real Fino” apricot showed the fastest recovery after re-irrigation while being one of the most affected cultivars. In addition, from the better response to these watering treatments by the almond genotypes, two different trends were observed after re-irrigation treatment that clearly differentiate the response of the almond cultivar “Garrigue” from the rest of Prunus genotypes. A better characterization of the short-term drought response in Prunus, an accurate and more efficient evaluation of the genotype effect was obtained from the use of mixed models considering appropriate variance–covariance structures. Although the advantages of these approaches are rarely used in Prunus breeding, these methodologies should be undertaken in the future by breeders to increase efficiency in developing new breeding materials.
