Abstract: SCS438 Zafira' is a novel plum cultivar, adapted to southern Brazil. It produces high-quality fruits, very similar to 'Fortune', the standard mid-season cultivar. Its main advantage is the resistance to leaf scald. Apparently, the mechanism of resistance blocks the transmission of the bacteria by natural insect vectors (sharpshooters).

“…The situation is different in Brazil for what concern plum production. Cultivation of plum has a great economic importance (Schneider et al, 2017) and the plum leaf scald (PLS) disease, caused by X. fastidiosa, represents a limiting factor for plum production (Dalbo et al, 2018). Symptoms are characterised by leaf scorch and brown rot but the disease produces low fruit quality affecting negatively the weight, the firmness and the size of the fruits (Kleina et al, 2018).…”

“…The spread of the PLS in Brazil is due to the presence of alternative hosts and efficient and widespread vectors (sharpshooters) (Dalb o et al, 2016). In the state of Santa Carolina, where the PLS disease caused damages to the 90% of plum orchards from 1975 to 1982 (Ducroquet and Mondi, 1997), was developed an intensive breeding programme using some cultivar selections from Florida (Dalbo et al, 2018). However, plum orchards usually have short-life term and the common used strategy is to plant healthy material and spray insecticides for the vector control (Dalbo et al, 2018).…”

“…In Brazil, where Japanese plum is widespread, the adoption of resistant or tolerant plants appears to be able to reduce the economic impact of PLS and restore the plum production sector. Breeding programs started in the 1990s, crossing cultivars from Florida (United States) and the delta of the Parana River (Argentina) with susceptible local cultivars (Dalbó et al, 2010(Dalbó et al, , 2016(Dalbó et al, , 2018. Unfortunately, initial tolerant cultivars, such as "Carazinho, " "Sanguinea, " "Chatard, " and "Piamontesa, " had a very low-quality production (Dalbó et al, 2016).…”

“…Unfortunately, initial tolerant cultivars, such as "Carazinho, " "Sanguinea, " "Chatard, " and "Piamontesa, " had a very low-quality production (Dalbó et al, 2016). However, the selection program created a cultivar with exceptional characteristics, i.e., "SCS438 Zafira, " which, besides being resistant to PLS, also produces high-quality fruits (Dalbó et al, 2018). Its tolerance appears to be due to the influence of the plant-on the-insect behavior of the vectors.…”
