F1 hybrid populations from crosses of 2 selections of V. berlandieri and 4 cultivars of V. vinifera showed generally low chloride accumulation, as in V. berlandieri, with some small variations related to particular parents. Backcross populations from crosses of 2 F1 hybrid selections and 2 of the cultivars of V. vinifera showed a discontinuous distribution with about half of each population showing low chloride accumulation as in V. berlandieri, and the rest higher chloride, although not as high as in the V. vinifera cultivars. Neither yield nor berry weight in the backcross populations was linked with chloride accumulation. Wines made from a few of the higher yielding backcross seedlings were comparable with wines from selections of V. vinifera.
Chloridanreicherung bei F1-Hybriden und Rückkreuzungen von Vitis berlandieri und Vitis vinifera
Die F1-Populationen aus der Kreuzung von 2 Vitis-berlandieri-Klonen und 4 V.-vinifera-Sorten zeigten im allgemeinen, ähnlich wie V. berlandieri, nur eine schwache Chloridanreicherung; geringfügige Abweichungen traten in Verbindung mit bestimmten Kreuzungseltern auf. Bei den Rückkreuzungspopulationen aus 2 F1-Klonen und 2 V.-vinifera-Sorten wurde eine diskontinuierliche Verteilung der Chloridanreicherung beobachtet; die einzelnen Populationen setzten sich jeweils etwa zur Hälfte aus Sämlingen mit schwacher und mit stärkerer Chloridanreicherung zusammen, die allerdings nicht so hoch wie bei den V.-vinifera-Sorten war. In den Rückkreuzungspopulationen waren weder Traubenertrag noch Beerengewicht mit der Chloridanreicherung verknüpft. Die Weine, die von etlichen der stärker tragenden Rückkreuzungssämlinge gewonnen wurden, waren den Weinen von V.-vinifera-Klonen vergleichbar.
