Per Winkler (see citation): "The phylloxera rootstock, SO4, is one of the seedlings arising from crosses by Teleki between V. berlandieri and V. riparia. In some respects it is similiar to the other Teleki hybrids, such as Teleki 5A, 5BB, etc. One principal difference, however, is its somewhat lower vigor. This underlies its popularity with growers in Northern Europe. It is quite tolerant to lime, is highly resistant to phylloxera, and roots fairly readily and grafts with ease. SO4 has only recently been placed in field trials in California vineyards. The moderate vigor of its scions indicates that it may not be suitable on high stress sites. For example, in a non-irrigated trial in Napa Valley, it has developed slowly, producing relatively small vines during the first few years. On the other hand, it may be quite satisfactory on irrigated, more fertile sites. This new stock to California deserves a thourough and intensive study in phylloxerated districts." | 1333949 | PI 439013 |

The vines are very vigorous and productive. Chenin blanc should do well with head or cordon-training and cane-pruning, which would spread the fruit and tend to reduce bunch rot. The clusters are large medim; long conical; compact; with a thick peduncle, medium to long. The pedicels are of medium size, with brown warts (lenticels). the berries are medium; oval; with tough skins. the canes are semi-erect; medium large with medium short internodes.

Cluster: medium, 15-20cm long, fairly compact, conical, with one or two wings; berries oval, 10-12mm, firm golden-yellow at maturity. Chenin blanc is known to have been growing in 845 A.D. on the left bank of the Loire in Anjou at the Abbey of Glanfeuil. Its present name dates from around the fifteenth century from Mont-Chenin in the Touraine region, and it is cited by name in the literature of Rabelais. The wine is very fruity with a lot of bouquet and in good years is worth aging. It generally contains some residual sugar since it lends itself to slightly sweet (or very sweet dessert wines) rather than dry wines. In addition it is oftenn made into sparkling wine, as in Vouvray, for example. Early budbreak exposes it to spring frosts. Maturity is midseason; sensitive to downy and powdery mildews, botrytis, and the grape berry moth | 1563998 | PI 277331 |

It is well adapted to fertile sandy and sandy-loam soils. Its moderate resistance to phylloxera, combined with its resistance to nematodes, is of great advantage where both pests occur - as in the central San Joaquin Valley. Table grape varieties grafted on 1613 grow with moderate vigor, and the fruit characteristics are generally good. The clusters tend to be medium-sized, well gormed, and loose; the berries are large and firm. The color of red table grapes has not been so brilliant as on its own rooted vines. Rootstock cuttings of 16 13 root easily in the nursery and graft readily to nearly all fruiting varieties. In unirrigated or very sandy soils of low fertility, 1613 has insufficient vigor, and vines grafted on it are weak and low in productivity. In comparative test under these soil conditions, the more vigorous Dog Ridge and Salt Creek rootstocks grow and produce much better than does 1613. Some instances of late maturity, low acidity, and poor coloring have been reported with 1613. Most of these cases, however, can be traced directly to virus disease carried over from the mother vines. With supply of certified disease-free planting stock now available, this should no longer be a problem. Despite its defects, this rootstock will continue to be widely used in California until a better stock is found. It is a generally useful stock, especially useful for table grapes on highly fertile soils infested with rootknot nematodes. The 1613 has large gray-green leaves, with few long hairs above and felty tomentum below; large veins noticeably set down; petiolar sinus wide and v-shaped; serrations large and sharp. Some seedy fruit is produced." | 1011274 | DVIT 1090 |

DESCRIPTION: Growing tip: downy, white with rose margin. Young leaves: cobwebby, green, more or less copper. Leaf: cuneiform, 136-3-24, entire, lateral sinuses 10, dull, yellowish, wavy, with upturned edges; petiolar sinus with a narrow V on narrow leaves which becomes an open U when adult; teeth convex, nearly flat; petiolar junction pink; petiole and veins pubescent. Flower: always sterile, male. Shoot: ribbed, purple nodes, slightly pubescent especially on the nodes. Cane: finely ribbed, glabrous with a few pubescent hairs on the nodes, dark chocolate brown, nodes inconspicuous; small, pointed buds. APTITUDES: This is a vigorous rootstock which develops especially rapidly at the start and, like Riparia tends to favor fruit set and advance maturity. In field trials in the Champagne district, the vines grafted on SO 4 had a greater average production than those on 161-49 C or 41 B, but slightly less than on 5 BB. In the Mediterranean region, SO 4 has been criticized for its slender trunk, which may fail to support a nontrelised, head-pruned vine with a heavy crop. Suited to humid, clay soils, it is not recommended for very dry conditions. Its resistance to active lime is approximately 17 to 18 percent and it has a good resistance to nematodes. According to Vidal and Marcelin (1968), it accepts up to 0.4g/kg salt content. SO 4 roots well. It field grafts well and bench grafts satisfactorily. It produces a large amount of propagating wood. Introduced in France in 1941, there was an extensive planting of mother vines mainly to satisfy the demand for graftable cuttings in Germany. It is now the number one rootstock variety in France."

Young leaves: cobwebby, yellowish-green, bronze on bulges. Leaf: medium, orbicular 035-2-5. Shoot: glabrous, finely ribbed, reddish brown in sun, pinkish nodes; tendrils small, thin. Cane: dull yellowish-brown, nodes slightly darker, bloom covering the whole cane. Cluster: small, 7-10 cm, cylindrical, compact, winged berries round, small, amber yellow at maturity. Chardonnay is the noble variety of the great white burgandies of Montrachet, Meursault, Chablis, Pouilly-Fuisse, and Maconnais blanc, and it is one of the principal varieties of the Champagne region. Has good relative resistance to low winter temperatures. Has some resistance to downy mildew, but is sensitive to powdery mildew and botrytis. [Chardonnay] is often long cane pruned and its production depends on the fertility of the soil and the health of the plant." Per website www.winelovers page.com/wineguest/wgg.html: Chardonnay wine is "possesing [of] a fruity character (e.g. Apple, lemon, citrus) subsequent barrel influenced flavors include 'oak', 'vanilla', and maloactic fermentation imparted 'creamy-buttery' components." Per Winkler (see citation): "When [Chardonnay] grows very vigorously, the crop may be increased by girdling. It should be cane pruned. The clusters are small; round; usually with one seed. The leaves are large, almost entire, with the basal veins often naked to the first branch." Unknown source: "Grows rapidly early in the season and develops long shoots that trail on the ground. Vines should be planted 8 ft. apart in the row. Harvest period early September at Oakville, Napa County. Susceptible to mold spoilage after autumn rains. The vines show marked symptoms and decline rapidly when affected by Pierce's disesase. Quite subject to spring frost injury.

Young leaves: downy, yellowish. Leaf: orbicular-reniform 025-2-46. Shoot: brownish-green with partially pink nodes; tnedrils pale yellow, thin, medium length. Cane: orange-yellow, nodes slightly darker, no bloom. Cluster: cylindrical, winged; berries golden white, medium, 12mm, oval. This variety comes frm the Charente region where it was first cultivated to furnish white wine to the Dutch who preferred its alcoholic, less herbaceous wine to that of Folle blanche. Colombard produces an ordinary table wine with a characteristic flavor. When distilled, it makes a good brandy whose quality is slightly inferior to that of Folle blanche or St. Emilion. Only moderately vigorous before the phylloxera crisis, Colombard responded to grafting by a much increased production, especially when cane pruned. Budbreak is a little after Folle blanche and maturity is about the same, midseason. Although it is very sensitive to powdery mildew, Colombard has some resistance to botrytis and thus may be left to hang longer on the vine. It also has some resistance to low winter temperatures." Per Winkler (see citation): "Before Prohibition the French Colombard was rather widely grown under the name of West's White Prolific. There is demand for more fruit of this variety. Its wine is also used for sparling wine stock. For this purpose the berries should not be permitted to become over ripe. It does well with cordon or head-training and spur or cane pruning depending on the location. The clusters are of medium size; long conical; well filled. The berries are medium; ellipsoidal; yellowish green, sometimes with a pink tinge; neutral in flavor and high in acid. The canes are semierect; large; with internodes of short to medium length. THe leaves are yellow-green; glabrous above, medium tomentose below; with green veins, shallow sinuses, and the petiolar sinus v-shaped." See also: www.wine-lovers-page.com. | 1008388 | DVIT 726 |

In California, it or a variety resembling it has been called Napa Gamay. It is a vigorous grower, and very productive when head-trained and spur pruned. The clusters are large medium; conical; well filled. Berries are large medium; round; with thick, tough skins. Ripening in late sesason. The leaves are medium large; almost entire; medium green; somewhat rough." Information taken from http://www.wine-lovers-page.com/wineguest/wgg.html: "At least three different vitis vinifera grape species are permitted to use the term 'Gamay' as their label-specified variety in the U.S.A. The Gamay Noir, Gamay Beaujolais and Napa Gamay. At one time or another each one was thought to be the true Pinot Noir variety of Burgandy before it was determind that many cepage clones existed. The Napa Gamay as grown in California is for the msot part identical with the Valdeguie variety grown in France. However, as a result of investigations by Dr. Olmo of University of California, Davis it was determined that several vineyards in the state contain the true Beaujolais Gamay Noir a Jus Blanc variety clone planted under the name of Napa Gamay, which accouints for its superior reputation." Unidentified source: "Clusters: medium-large, about 1/2 to 2/3 lb., cylindrical, winged, well-filled to compact, the peduncle short and hard. Berries: large, about 2g or more, round, black covered with whitish bloom, neutral flavor, juicy, somewhat crisp; the skins are thick and tough. Growth and Soil Adaptability: a moderately vigorous grower, but less than average udner heavy cropping; does well on a fairly wide range of soil types. Production: very productive at 5 to 7 tons per acre. Harvest Period: mid-october to early November. Special Insect and Disease Problems: leafroll is widely found in older plantings. This virus disease retards sugar development in the fruit and also reduces crop and vine growth." | 1008434 | DVIT 732 |

Unknown Source: "Clusters: medium-small in size, about 1/5 to 1/3 lb; shouldered and slightly conical, compact. Berries: Medium in size, long oval, with very firm texture; greenish-pink to dull reddish-tan; flavor neutral to mildly spicy. Growth and Adaptability: A very vigorous, upright growing variety with abundant foliage. Canes are thick with rather short internodes. Adapted to a wide range of soils. The vines leaf out fairly early in the spring. A good producer at 5 to 7 tons per acre. Harvest period: One of the earliest wine grape varieties to ripen - late August to early September. Training and Pruning: Bears well with spur pruning. Special Insect and Disease Problems: The bunches are quite susceptbile to Botrytis bunch rot; this problem is aggravated by dense foliage and heavy massing of fruit. Young shoot growth in the spring is susceptible to stunting after heavy feeding by flower thrips." | 1008516 | DVIT 745 |

The vines are moderately vigorous and productive. It does well with head-training and spur-pruning. The clusters are medium in size; long conical; well filled to compact. The berries are small medium; oval; reddish brown. The seeds have a long, plump beak. The leaves are dull above, lightly tomentose below; some with shallow sinuses, but many entire. The leaves are small medium size. The Grignolino normally produces an orange-pink wine that is distinctly different from most rose wines. When it is blended to produce a red table wine, it loses one of its outstanding characteristics - its color - and becomes simply another red wine."

Mataro wines lack varietal characteristics and have low acidity and color. In most location the Carignane is preferred because of its greater vigor and higher productivity. The Mataro is less susceptible to powdery mildew than the Carignane, however, and also starts its buds slightly later in the spring, a characteristic that may be important in locations subject to spring frost. The clusters are large medium in size; usually two-shouldered, conical; compact. The berries are medium sized; spherical; black, with a heavy blue bloom; firm; pulpy; ripening in late mid-season. The vines are moderately vigorous, erect in growth, and moderately productive with head training and spur-pruning." Information taken from http//www.wine-lovers-page.com/wineguest/wgg.html: "Robust mediterranean hot climate grape variety widely grown in the southern Rhone region of France and mainly used to introduce color and body to the red wine blends. Normally ripens in mid-October, i.e. a week or so after Carignan. Select limited plantings occur in California, where the variety is often called the Mataro, a relationship recently confirmed (3/98) by DNA analysis at UC Davis, and are used to produce a wine that sometimes develops the "green tea-like" herbal character that Rhone region french growers refer to as 'animale'. Common aliases, probably due to early mis-identification, in Australia are Mataro, Morrastel and Graciano. The cultivar known as Monastrell that is grown in Spain and previously thought to be identical is not related." | 1009119 | DVIT 819 |

The vines are of only average vigor and are moderately productive--about 7 tons per acre in region IV. Its wines are rich in muscat aroma, but not so delicate and rich in aroma as those of Muscat blanc. In favorable locations its wines surpass those of Muscat of Alexandria. The variety is adapted to regions IV and V. Head-training with spur-pruning is satisfactory. The Orange Muscat should find a place in region IV--where Muscat blanc will sunburn in certain years and Muscat of Alexandria will fail to mature properly. The clusters are of medium size; short conical; compact. The berries are medium; oblate to round; firm; orange in color. The leaves are dark green, with rounded sections and depressed veins; the petiolar sinus is only a slit or is closed." | 1009617 | DVIT 879 |

With cordon-training and spur- or cane-pruning to spread the fruit, its performance has been satisfactory. It produces excellent port-type wines. It is adapted to regions II, IV, and V, and is recommended for further planting. In recent years considerable tonnage has found its way to the standard red table wines of the interior valley where its deep color and rich flavor have improved quality. The clusters are of medium large size; broad conical, winged; well filled to compact. The berries are medium; long oval; jet black. Some undeveloped small green berries are usually present.

Per Winkler (see citation): "The Valdepenas comes from east-central Spain. It ranks with the most vigorous and productive of grape varieties. Generally its wines from region IV grapes are low in acidity and lacking definite character. They have been clean, standard-quality, red table wines. Nevertheless, it is probably the best adapted to regoin IV, where it may find consideration for the production of bulk wines because of its productivity. Beyond this it cannot be recommended. The clusters are medium-sized to large; long conical, well filled, shouldered to irregular. The berries are small medium; oblate; black; with gelatinous pulp.

The vines are very vigorous and productive. Chenin blanc should do well with head or cordon-training and cane-pruning, which would spread the fruit and tend to reduce bunch rot. The clusters are large medim; long conical; compact; with a thick peduncle, medium to long. The pedicels are of medium size, with brown warts (lenticels). the berries are medium; oval; with tough skins. the canes are semi-erect; medium large with medium short internodes.

Per Galet (see citation): "Growing tip: felty, white with rose margin. Young leaves: downy above, felty below, bronze patches. Leaf: orbicular 025-2-58. Shoot: glabrous, mahogany red on side exposed to sun, with brown streaks on the back; long, thick, red tendrils. Cane: clear beige with darker nodes. Cluster: medium, 15-20cm long, fairly compact, conical, with one or two wings; berries oval, 10-12mm, firm golden-yellow at maturity. Chenin blanc is known to have been growing in 845 A.D. on the left bank of the Loire in Anjou at the Abbey of Glanfeuil. Its present name dates from around the fifteenth century from Mont-Chenin in the Touraine region, and it is cited by name in the literature of Rabelais. The wine is very fruity with a lot of bouquet and in good years is worth aging. It generally contains some residual sugar since it lends itself to slightly sweet (or very sweet dessert wines) rather than dry wines. In addition it is oftenn made into sparkling wine, as in Vouvray, for example. Early budbreak exposes it to spring frosts. Maturity is midseason; sensitive to downy and powdery mildews, botrytis, and the grape berry moth." | 1008110 | DVIT 691 |
