Further studies on breeding for resistance to Botrytis cinerea in red raspberry canes.

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