The Citrus Variety Improvement Program in Spain (CVIPS) After Four Years

Virus and viruslike diseases cause great economic losses to the Spanish citrus industry (Navarro, 1977). Practically 100 per cent of our local selections are infected with one to several viruses. In 1975 we started the Citrus Variety Improvement Program in Spain (CVIPS) to obtain virus-free citrus p...

Sumario:Virus and viruslike diseases cause great economic losses to the Spanish citrus industry (Navarro, 1977). Practically 100 per cent of our local selections are infected with one to several viruses. In 1975 we started the Citrus Variety Improvement Program in Spain (CVIPS) to obtain virus-free citrus plants of all our commercial cultivars and to release healthy budwood to the growers as soon as possible (Navarro, 1976). The program is based on the technique of shoottip grafting in vitro (STG) (Navarro et al., 1975). Simultaneously, we carry on an auxiliary program to develop nucellar plants of our most important cultivars (Navarro, 1976, 1977). In this paper we report the status of both programs and discuss their future development.
