Resistance of cocoa to swollen-shoot virus in Ghana. II. Assessment of seed inoculation experiments



Resistance of cocoa to swollen-shoot virus in Ghana. II. Assessment of seed inoculation experiments



Annals of Applied Biology 97(1): 91-97



In this second part of a series on the resistance of cacao to cocoa swollen-shoot virus (CSSV) in Ghana (see preceding abstract), an account is given of studies carried out to assess seed inoculation experiments. Differences in infection levels following seed inoculation by the mealybug vector Planococcoides njalensis (Laing) were used as a short-term test of virus resistance in a range of cacao progenies. The results were highly correlated with virus resistance determined in field tests.
