1 THE ROLE OF CLEMENTINES IN THE SPANISH CITRUS INDUSTRY Salvador Zaragoza Luis Navarro Instituto Valenciano de Investigaciones Agrarias Moncada, Valencia, España

2 Background of mandarin growing in Spain 1854 Willow Leaf: Castellón, Villarreal Easy peeling, flavour, seeds, alternate yield Clementine Fina from Algeria: Seedless, low production, low size Clementine Monreal from Algeria Seedy, high production 1962 Clemenules: high yield, good size 1962 Oroval: early, high yield, good size

3 Clementines are genetically instable and produce many budsport mutations
