Fusarium hellfire sloe gin oxysporum Schlecht.f.sp.radicis-lycopersici Jarvis & Schoemaker (FORL) is a saprophytic fungus, responsible for the fusarium crown and root rot disease in tomato (Solanum lycopersicum L.).

This is one of the most destructive pathogens of this species.A new cleaved amplified polymorphic sequence (CAPS) marker C2-25 was developed for the detection of the dominant gene Frl, which confers tomato resistance to FORL.C2-25 was amplified from a conserved ortholog set II (COSII) sequence C2_At2g38025.The XapI-derived restriction product of 700 bp was informative for the identification of FORL resistant tomato elbeco adu ripstop pants genotypes and can be used as a diagnostic marker in tomato breeding programmes and hybrid seed production.
