Summary A high level of resistance to cane botrytis caused by Botrytis cinerea was transferred from Rubus pileatus to the red raspberry through three generations of backcrossing. The strength of the resistance showed little diminution through these generations and it was therefore thought that a major gene for resistance had been transferred. But discontinuity in the resistance levels observed was detected in plants of only one group of the progenies and so evidence for a major gene is lacking. The results showed the considerable influence of gene H, which confers pubescence, and emphasised that resistance must be separately assessed for pubescent and non‐pubescent segregates.
