Identification of late blight resistance QTLs <i>in an interspecific RIL population of tomato</i> via genotyping-by-sequencing.

ABSTRACT: Late blight (LB), caused by Phytophthora infestans, is a destructive disease of the cultivated tomato, Solanum lycopersicum. Environmental concerns and pathogen resistance have propelled research towards developing host resistance. The current LB-resistant cultivars of tomato exhibit susceptibility under severe disease pressure, necessitating the identification, characterization, and incorporation of additional resistance genes into new tomato cultivars. Recently, we identified Solanum pimpinellifolium accession PI 270443 with strong resistance to LB and developed a RIL population from its cross with an LB-susceptible tomato breeding line. In the present study, we constructed a high-density genetic map of the RIL population, using 8,470 SNP markers set into 1,195 genom
