| Abstract: | The terpenoid fractions of bud extracts from blackcurrant genotypes showing resistance or susceptibility to gall mite (Cecidophyopsis ribis) infestation were examined and compared using gas chromatography. By the use of discriminant analysis, and the application of the derived discriminator to the data, resistance status was correctly predicted in 88% of the genotypes sampled. The use of metabolic profiling provides a useful alternative to lengthy field assessments. |
