Use of St. George should be avoided with small-clustered or loose-clustered varieties on fertile soils. Susceptible to nematodes and supports high populations of phylloxera. However, there are no examples of failure to phylloxera in the field. St. George leaves fold flat on themselves, shiny green and bean-shaped.

Teleki 5C

COMMON SYNONYM: 5C, Geisenheim 5C, Teleki 5C
COUNTRY OF ORIGIN: Hungary
