The susceptibility of four common grapevine rootstocks (10114 Schwarzmann 5C and Riparia Gloire) to Cylindrocladiella parva (black foot disease) infection was assessed in a pot experiment The roots of 4monthold callused rooted cuttings were wounded in situ and inoculated with 50 ml C parva conidial suspension (106/ml) or sterile water (controls) After 6 months of growth shoot dry weight was significantly higher for control plants (242 g) than for those inoculated with C parva (165 g) but did not differ between rootstock varieties Root dry weight was not significantly affected by C parva inoculation but root dry weight of 10114 was significantly higher than other rootstocks Incidence and severity of trunk infection were significantly affected by rootstock variety being lowest in rootstock 10114 plants than other rootstocks None of the rootstocks tested was resistant to this pathogen
