“…The Wageningen University hosts a database (SolRgenes) of resistance sources (Vleeshouwerrs et al 2011). Rodewald andTrognitz (2013), Nachtigall et al (2018), Sliwka et al (2019) and Blossei et al (2022) have extensively listed the sources of R/Rpi genes of late blight resistance. Maximum of 15 late blight resistant genes in a Solanum species have been reported in S. demissum followed by 5 each in S. bulbocastanum and S. stoloniferum.…”

Improving host resistance to late blight (Phytophthora infestans) has been a major concern of potato breeders since the Irish famine of 1840s. Since then, a number of late blight resistant potato (Solanum tuberosum L.) cultivars have been developed using both conventional and molecular techniques. However, resistance to late blight did not last long and broke down due to the emergence of more virulent races of Phytophthora infestans. This perspective paper presents the status of sources of resistance to late blight, defence mechanism of host against the pathogen and late blight resistance genes mapped, cloned, and transferred to cultivated potato. Considerable progress has been made in all aspects of breeding potato for resistance to late blight. However, a critical appraisal of the status of potato breeding for resistance to late blight suggests the continued need to identify new sources of resistance, transfer of resistance genes from diverse sources and stacking them in maximum number into individual plants. Other breeding strategies to combat this dreaded disease are also discussed.
