Positioning Portugal in the Context of World Almond Production and Research

Abstract

Almond production plays a very significant role in the Portuguese socio-economic context, especially with regard to dried fruit production. Indeed, Portugal is the third largest almond producer in Europe, producing 41,450 t of almonds in shells in 2021. This is due to its edaphoclimatic conditions that are favorable for its production. Traditionally, the north region of “Trás-os-Montes” has stood out as one of the most relevant for Portuguese almond production and bioeconomy. However, production in “Alentejo“ and “Beira Interior” will surpass the northern region in a short time as a result of the installation of new orchards. Despite its importance, there is a need to uncover genetic traits underlying phenotypic desirable traits needed to improve yield and quality but also cope and mitigate the impacts of climate change on their production. To address this, it is important to characterize the genetic resources available and the germplasm collection since they are crucial players for conservation and breeding initiatives. In this review, we describe the main cultivars of almonds cultivated in Portugal and their productive challenges. We also provide an overview of the main genetic resources available, breeding goals, and accomplishments regarding their improvement towards biotic and abiotic constraints in both Portugal and the rest of the world.

“…Portugal also plays an important role, as it is the country with the most incredible increase in production over the last decade (2012-2022: +544%). Additionally, notable production rates are observed in countries such as Tunisia, Iran, Chile, Turkey, and Morocco [5,16].…”
