Abstract
Abstract Apple is one of the main agribusiness products of temperate-zone fruits in Southern Brazil. More than 90% of apple production is obtained from only two apple cultivars – Gala and Fuji and their mutations. These apple varieties are insufficiently adapted to the regional climate and ‘Gala’ and its mutations are also susceptible to glomerella leaf spot – GLS, currently the main apple disease in Brazil. ‘SCS425 Luiza’ cultivar was developed by Epagri / Estação Experimental Caçador, aiming to offer to the production chain an early apple variety better adapted to the environmental conditions of Southern Brazil and resistant to GLS. ‘SCS425 Luiza’ cultivar was obtained by artificial hybridization carried out in 2001 using the cultivars Imperatriz and Cripps Pink as parents. ‘SCS425 Luiza’ has lower chilling requirement compared to ‘Galaxy’, higher flowering precocity and yield potential at least equivalent to ‘Galaxy’. It produces fruits with skin finish, flavor and flesh texture adequate for the Brazilian market and storability similar to ‘Galaxy’ apples when harvested at the same maturity.

‘SCS 425 Luiza’: nova cultivar de macieira de médio requerimento de frio hibernal e resistente à mancha foliar de glomerella
The profit margin of producers has reduced in the last decades, as a reflection of the increase of production costs in relation to selling prices (FIORAVANÇO; LAZZAROTTO, 2012)
The poor availability of commercial cultivar options is among the limitations of the Brazilian apple production chain, with predominance of Gala and Fuji clones (KVITSCHAL; DENARDI, 2011; FIORAVANÇO; LAZZAROTTO, 2012)
Summary
‘SCS 425 Luiza’: nova cultivar de macieira de médio requerimento de frio hibernal e resistente à mancha foliar de glomerella (collectorichum spp.). The development and availability of new apple cultivars better adapted to the different growing environments of Southern Brazil, resistant to the main diseases and with high quality standard, represent the main focus of the Apple Breeding Program carried out at Epagri (DENARDI et al, 2013, KVITSCHAL et al, 2013).
