A field experiment in Ghana on the tolerance of cocoa seedlings to cocoa swollen-shoot and cocoa mottle-leaf viruses



A field experiment in Ghana on the tolerance of cocoa seedlings to cocoa swollen-shoot and cocoa mottle-leaf viruses



Ann Appl Biol 57(3): 389-396



Seedlings of Amelonado cocoa and of 2 progenies obtained by crossing Iquitos (Upper Amazon) parents were infected with 3 strains of cocoa swollen-shoot virus (CSSV) and with cocoa mottle-leaf virus (CMLV). CSSV strain 1A had the most severe effects on the growth of Amelonado than on the Iquitos progenies, except that CSSV strain 1W affected the growth of Amelonado and one of the Iquitos progenies equally, as did CMLV which caused the greatest decrease in the 1st crop of all varieties. The relative virulence of different CSSV strains in any one variety can be assessed from single criteria such as length of latent period or effect on growth; CMLV had a shorter latent period than CSSV strain 1A but less effect on growth.
