In addition, tests have not been conducted to determine whether these rootstocks are compatible with our cultivars or whether they are sensitive to our viruses. The Weiroot rootstocks will be included in the next NC-140 trial for direct comparison against the better Gisela rootstocks. In addition, a consortium of scientists from Oregon and Washington, called the Genotype Research Consortium, will be testing the Weiroot stocks for susceptibilities. As scientists evaluate these rootstocks, growers should consider small test plots to determine their suitability for their local conditions. Mature tree height is 12 to 18 feet, depending on the training system utilized.
Precocity is good as well as fruit size.
It exhibits good anchorage and does not need staking. A good choice for poorer soils. This rootstock is quickly gaining favor in Germany since it combines the best yields with good fruit size. Central leader trees on this stock typically grow 12 to 15 feet tall. Best results are obtained on good soils.
