<i>Crop Science</i> special issue: Adapting agriculture to climate change: A walk on the wild side

Plant domestication and crop improvement have resulted in reduced genetic diversity in most of our cultivated crops, thus limiting their potential to adapt to future challenges (Byrne et al., 2018; Keneni, Bekele, Imtiaz, & Dagne, 2012; Tanksley & McCouch, 1997; Swarup et al., 2020). One response to mitigate the impact of climate change on agricultural systems is to develop improved varieties that are genetically tolerant or resistant to the new range of abiotic and biotic challenges. Improvement via crop breeding requires access to novel variants of genes for complex adaptive traits. Crop wild relatives (CWR) and landraces are a potentially valuable source of these alleles (Cossani & Reynolds, 2015; Seiler, QiL, & Marek, 2017). However, these materials are often difficult…
