“…Nevertheless, reproductive barriers, such as self‐incompatibility, sterility and unilateral incompatibility, can be obstacles to the introgression of genes from wild species in commercial tomatoes, reducing the options for interspecific crossings (Peralta & Spooner, 2000; Peralta et al, 2008; Chetelat, 2016). However, some wild tomatoes, such as Solanum pennellii Correl, have shown good compatibility with domesticated tomatoes, allowing gene introgression (Eshed & Zamir, 1995; Resende et al, 2022; Zeist et al, 2021). S. pennellii is a species originated from South America that is able to grow and reproduce in dry and saline soils, being a valuable source for breeding programmes focused on drought tolerance (Iba, 2002; Ramírez‐Ojeda et al, 2021; Solankey et al, 2015).…”
