The multi-site PeachRefPop collection: a true cultural heritage and international scientific tool for fruit trees

Abstract : Plants have evolved a range of adaptive mechanisms that adjust their development and physiology to variable external conditions, particularly in perennial species subjected to long-term interplay with the environment. Exploiting the allelic diversity within available germplasm and leveraging the knowledge of the mechanisms regulating genotype interaction with the environment are crucial to address climatic challenges and assist the breeding of novel cultivars with improved resilience. The development of multisite collections is of utmost importance for the conservation and utilization of genetic materials and will greatly facilitate the dissection of genotype-by-environment interaction. Such resources are still lacking for perennial trees, especially with the intrinsic difficulties of successful propagation, material exchange and living collection maintenance. This work describes the concept, design and realization of the first multi-site peach [Prunus persica (L.) Batsch] reference collection (PeachRefPop: PRP) located across different European countries and sharing the same experimental design. Other than an invaluable tool for scientific studies in perennial species, the PRP provides a milestone in an international collaborative project for the conservation and exploitation of European peach germplasm resources and, ultimately, as a true heritage for future generations.
