Screening for Resistance Resources against Bacterial Wilt in Wild Potato

The study investigates resistance to bacterial wilt, caused by Ralstonia solanacearum, in wild potato species to address significant agricultural losses. By screening 55 accessions from nine wild potato species, the research identifies three highly resistant genotypes: ACL24-2 (Solanum acaule), PNT204-23, and PNT880-3 (Solanum pinnatisectum). Among them, PNT880-3 demonstrates strong breeding potential due to its diploid nature and viable pollen. The research explores genetic and phenotypic resistance mechanisms and proposes integrating these traits into cultivated varieties through hybrid breeding, somatic hybridization, and other biotechnological approaches. This work provides valuable genetic resources for developing bacterial wilt-resistant potato cultivars.
