SUMMARY In tests using seed, the resistance of cocoa progenies to primary infection with cocoa swollen‐shoot virus by mealybugs was stable to inoculum pressure and effective against several virus strains. The results suggested that the resistance would be effective throughout the cocoa growing areas of Ghana. There were indications that resistance factors from different cocoa populations could be accumulated to give progenies of higher resistance than presently available.
