Rootstock Crosses and Their Resistance to Phylloxera and Nematodes
Rootstock cross and main

Phylloxera

Comments
Nematode resistance
Comments
Vitis riparia
×
V. rupestris
101-14 Millardet,
Schwarzmann, 3309
and 3306 Couderc
Good
Confer low to moderate vigor on
scions; more suited to cooler,
wetter regions
Variable, according
to nematode
species
Schwarzmann has best resistance, particularly
to
Meloidogyne
species, but has been found
susceptible to
T. semipenetrans
and
P. vulnus
and some virulent species of
Meloidogyne
in the
United States
V. berlandieri
×
V. riparia
SO4, 5C Teleki, 5BB
Kober, 420A Millardet
Good
Confer moderate vigor and early
ripening; 5C Teleki may be too
vigorous on deep sandy soils
Moderate to high,
according to
nematode species
SO4, 5C Teleki and 5BB Kober have better
nematode resistance than 420A Millardet; poor
resistance to
X. index
V. berlandieri
×
V. rupestris
1103 Paulsen, 99 and 110
Richter, 140 Ruggeri
High
Confer moderate to high vigor
(140 Ruggeri is the most
vigorous); suited to drier
regions
Moderate to high,
according to
nematode species
In Australia, 1103 Paulsen has not performed well
on sandy soils with high nematode populations
V. champanii
(
V. rupestris
x
V. candicans
)
Ramsey, Dog Ridge,
Freedom, Harmony
Good
Confer high to very high vigor,
especially Ramsey and Dog
Ridge on deep sandy soils that
are well watered
Very high
Best adapted to hotter climates under irrigation
(good wine quality requires regulated deficit
irrigation); best adapted to sandy soils because
of their nematode resistance; Ramsey is widely
used in inland Australia
V. vinifera
crosses with
V. berlandieri,
Fercal,
41 B
Poor
Rootstocks with vinifera parentage
are suspect for phylloxera
resistance
Poor to moderate
Not recommended, except in situations where
lime-tolerance is most important
New CSIRO rootstocks,
Merbein 5489, 5512
and 6262
Good
Confer low to moderate vigor;
good vine balance
High
Merbein 5512 and 6262 tolerant of an aggressive
strain of
M. javanica
, but Merbein 5489 is
susceptible
