SUMMARY The sensitivity of 20 genotypes from each of 13 progenies of parental potato clones was assessed using recently developed glasshouse testing procedures. Significant heritable differences between the progenies with respect to their degree of sensitivity to TRV were observed. Significant general and specific combining abilities were also demonstrated. The results are discussed in relation to modes of inheritance of this trait. The results indicate that though a major gene for TRV insensitivity may be operating this does not explain all the observed variation and it is suggested that there is also a system inherited in a polygenic manner that can confer good levels of insensitivity to TRV.
