A) Temperature in (minus) degrees Centigrade where close to 50% of the primary buds are killed.

B)Hardiness after a warm period in winter: G = good, B = bad, ? = unknown.

C)Wood Maturation: E = early, M = midseason, L = late.

D)Bud Burst in Spring: E = early, M = midseason, L = late.

E)Disease Susceptibility - Downy Mildew: VS = very susceptible, S = susceptible, R = resistant.

F)Disease Susceptibility - Botrytis: VS = very susceptible, S = susceptible, R = resistant.

G)Disease Susceptibility - Powdery Mildew: VS = very susceptible, S = susceptible, R = resistant.

H)Growth Patterns - Shoot Growth: E = erect, SE = semi-erect, SD = semi-drooping, D = drooping.

I)Growth Patterns - Internode length: L = long, M = medium, S = short.

J)Growth Patterns - Vigour: VH = very high, H = high, M = medium, L = low.

K)Productivity - Bud Fertility: H = high, M = medium, L = low.

L)Productivity - Bunch Size: S = small, M = medium, L = large.

M)Productivity - Yield: H = high, M = medium, L = low.

N)Main Use: R = red wine, W = white wine, T = table grape, I = icewine possibility?

O) Other information:
1) Shoot could break off in strong winds in June
2) Susceptibility to anthracnose
3) Susceptibility to phomopsis
4) Berries fall at maturity
5) Susceptibility to flower shattering
6) Berries split easily
