Introgression of Septoria Leaf Spot Resistance from Wild Solanum Species into Cultivated Tomato via Ovule Rescue, Bridging Backcrosses, and Identification of Candidate Resistance Loci.
Septoria leaf spot (SLS), caused by Septoria lycopersici Speg., is an important and increasingly prevalent foliar disease of tomato (Solanum lycopersicum L.) with no commercially resistant cultivars available. We screened 22 cultivated and wild accessions against a prevalent S. lycopersici isolate (WV21-1) and identifi...
