The grape industry in New York is interested in establishing new vineyards of both old and new varieties. Because there are not enough choice sites available, some will be replantings of old vineyards, others may be on shallow soils. To assume success in such situations, there is a need for vines grafted upon resistant rootstocks.
For nearly 100 years, viticulturists over the world have shown the benefits from employing rootstocks resistant to phylloxera; recently in California also for their resistance to parasitic nematodes. Research in New York over the past 50 years has shown also that resistant stocks can be used to advantage in vineyards on this Station. Recommendations concerning their use have been offered to growers for many of these years.
