Wine Grape Varieties

Camminare Noir

Camminare Noir – Pierce’s Disease Resistant Winegrape (Vitis Vinifera)

This red wine grape is 94% V. vinifera, makes wines with characteristics of both Cabernet Sauvignon and Petite Sirah and is resistant to Pierce’s Disease. It is established in large test plots along the Napa River and commercial scale wines have been made from this plot. This selection is one of the earliest to break dormancy, and it also blooms and ripens early. The berries are relatively large and the well-filled clusters are medium in size. This selection has been repeatedly tested in a UC Davis greenhouse screen and is highly resistant to Pierce’s Disease. It has ranked highly at numerous tastings of both Davis and Napa grown fruit. Tasting notes include: dark-red purple color, bright red fruit, raspberry, cherry, ripe, tannic, elegant rather than dense.

Technical: This variety was bred by Dr. Andrew Walker and is 50% Petite Sirah and 25% Cabernet Sauvignon.

Commercial Availability

Producers can obtain Camminare Noir from commercial nurseries licensed by the University of California. See Licensed Nurseries List.

Paseante Noir

Paseante Noir – Pierce’s Disease Resistant Winegrape (Vitis Vinifera)

This red wine grape is 97% V. vinifera, has characteristics of Zinfandel
Cabernet Sauvignon and is highly resistant to Pierce’s Disease. It is
established in field trials in Temecula and along the Napa River, where
commercial scale wines have been made. It blooms relatively late, but
ripens mid-season. The berries are medium and the clusters are
well-filled and relatively large. Although this selection is spur fruitful it
typically has only one cluster per shoot and is more productive with
cane pruning. Wines from this selection have been ranked highly at
numerous tastings of Davis and Napa grown fruit. Tasting comments
include: medium dark red with purple; berry pie, cassis, black olive,
herbal, dried hay, coffee, vegetal like Cabernet Sauvignon, licorice,
round, moderate tannins, soft finish.

Technical: This red wine grape variety was bred by Dr. Andrew Walker
and is 50% Zinfandel, 25% Petite Sirah, and 12.5% Cabernet Sauvignon.

Commercial Availability

Producers can obtain Paseante Noir from commercial nurseries licensed by the University of California. See Licensed Nurseries List.

Errante Noir

This red wine grape is 97% V. vinifera, has great blending potential and
is highly resistant to Pierce’s Disease in repeated greenhouse and field
evaluations. It has a mid-season bloom and ripening period and has
relatively large berries and loose clusters. It is highly productive. Wines
have been made from Davis fruit and they ranked very highly with
tasting comments including: dark- red purple color; complex fruit with
herbs and earth, plum, big wine, dense, rich middle, tannic yet
balanced. This red wine grape was rated as having great blending
potential with Cabernet Sauvignon. It’s high levels of high-quality tannin

Sylvaner and 12.5% each of Cabernet Sauvignon, Carignane, and
Chardonnay.

Grape Rootstock Varieties

GRN-1

The GRN-1 Cultivar

This selection is one of five nematode resistant rootstocks released by Dr. Andy Walker in 2008. This selection is the most resistant of the five and is a Vitis rupestris x Muscadinia rotundifolia hybrid. One of the the rare sources of resistance to ring nematode, this cultivar has extremely strong and broad nematode resistance, and is a member of a group of Vitis species x M. rotundifolia selections currently being tested for their ability to induce fanleaf tolerance. Mother vines have sterile flowers, moderately-long shoots with shorter internodes and more laterals than the other four rootstocks.

Commercial Availability

Grape growers can obtain GRN-1 from commercial nurseries licensed by the University of California. See Licensed Nurseries List.

GRN-2

The GRN-2 Cultivar

GRN-2™ acquires its nematodi resistance from V. rufotomentosa and V. champinii ‘Dog Ridge’. It roots and grafts easily. This cultivar has staminate flowers, long shoots and internodes and few laterals. It produces roots with relatively shallow rooting angles. It is susceptible to citrus and ring nematodes but has excellent resistance to root-knot and dagger nematodes.

Commercial Availability

Grape growers can obtain GRN-2 from commercial nurseries licensed by the University of California. See Licensed Nurseries List.

GRN-3

The GRN-3 Cultivar

UCD GRN-3™ and UCD GRN-4™ are siblings. GRN-3™ has strong nematode resistance from V. rufotomentosa, V. champinii ‘Dog ridge’ and c9038 (a wild collection from Texas that appears to contain V. monticola, a species with exceptional drought and mineral tolerance). Vitis monticola is the only Vitis species that is truly drought tolerant and grows on pure limestone on mesquite and juniper in central Texas. This selection produces moderate vigor mothervines with long canes and moderate lateral production. Cuttings root very well and their rooting angles are intermediate in depth. It has excellent nematode resistance and has moderate resistance to ring nematode. This selection resembles V. champinii, while its sibling appears more V. riparia-like. Nevertheless, the rooting angles of the two siblings are similar. UCD GRN-4™ has slightly lower nematode resistance than UCD GRN-3™ but is a more vigorous mothervine.

Commercial Availability

Grape growers can obtain GRN-3 from commercial nurseries licensed by the University of California. See Licensed Nurseries List.

GRN-4

The GRN-4 Cultivar

UCD GRN-3™ and UCD GRN-4™ are siblings. UCD GRN-4™ has good resistance to root-knot and dagger nematodes and also resists citrus and lesion nematodes – it is susceptible to ring nematodes (sibling UCD GRN-3™ has moderate resistance to ring nematodes). Cuttings root well and rooting angles are intermediate in length. This selection resembles V. riparia more than its sibling does. UCD GRN-4™ has slightly lower nematode resistance than UCD GRN-3™ but is a more vigorous mother vine.

Commercial Availability

Grape growers can obtain GRN-4 from commercial nurseries licensed by the University of California. See Licensed Nurseries List.

GRN-5

The GRN-5 Cultivar

This selection has strong and broad nematode resistance derived from V. champinii ‘Ramsey’ and from c9021 (a form of V. champinii that appears to intergrade with V. berlandieri). This selection has excellent root-knot and dagger nematode resistance, resists citrus and lesion nematodes, and supports low numbers of ring nematodes. This rootstock supported the highest level of nodosity-based phylloxera. Vitis riparia was used to improve the rooting and grafting of cuttings. Cuttings produce moderately sized roots with relatively deep rooting angles.

Commercial Availability

Grape growers can obtain GRN-5 from commercial nurseries licensed by the University of California. See Licensed Nurseries List.
