As other rootstocks became available, there was a noticeable move away from those two selections due to either excessive vigor in good soils, not enough vigor and a tendency to be drought stressed in shallower soils, plus a variety of other issues that viticulturists didn���t like. Next, 101-14 became somewhat of a ���darling��� due to its tendency to produce compact growth and advance ripening somewhat as well as its relative ease L.G. S ing conditions. Unfortunately, testing and evaluation of new varieties and clones is a low priority for the winegrowing industry. This is short sighted, given the huge effect that proper clonal selection could make on improving wine quality. Tops and rootstock leaves are cut off grafted vines so only the grafted bud or shoot shows. SEE US AT UNIFIED, BOOTH #938 Win es & Vin es JA N UA RY 20 13 145
