Narrative

Per Winkler (see citation): "At present, the most useful nematode-resistant stock for grapes in California is the hybrid Solonis X Othello 1613. 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."
