Tritordeum: a versatile and resilient cereal for Mediterranean agriculture and sustainable food production

Abstract

This review paper provides an in-depth analysis of × Tritordeum [(Ascherson et Graebner)], a novel cereal crop with promising agronomic, nutritional, and economic potential. Through a comprehensive examination of the crop's agronomic characteristics and management requirements, we highlight its adaptability to Mediterranean climates, resilience under changing environmental conditions, and potential applications in the food industry, such as breadmaking and pasta production. We also discuss the role of digital agriculture technologies in optimizing tritordeum cultivation and their potential impact on agricultural practices. Furthermore, we assess the opportunities and challenges associated with tritordeum's integration into the agricultural economy and production systems, emphasizing its potential to contribute to a more sustainable and health-conscious food system. By offering a holistic understanding of tritordeum's attributes, this review serves as a valuable resource for researchers, agronomists, food manufacturers, and policymakers interested in exploring the potential of this innovative cereal grain.

“…However, using less related gene pools in wheat breeding widens its genetic basis, improving resilience and quality (Kumar et al, 2022). This approach is of utmost importance under climate change, threatening biodiversity and agriculture worldwide (Kumar et al, 2022;Papadopoulos et al, 2023;Stoyanov, 2015;Villegas et al, 2010).…”

“…Despite the tritordeum limiting factors, namely, reduced plant growth, kernel weight, delayed anthesis and brittle rachis (Martín et al, 1998;Millán et al, 1988;Papadopoulos et al, 2023;Villegas et al, 2010) that should be further improved, its meiotic regularity along with its tolerance to drought and salinity, water-use efficiency, versatility, requirement of low inputs, high nutritional value and high adaptation to the Mediterranean region leverage the potential of this crop for sustainable agriculture, food security and industry ( Ávila et al, 2021;Naranjo, 2019;Papadopoulos et al, 2023;Shewry et al, 2023;Villegas et al, 2010).…”
