Summary: Two one-acre blocks of WA 38 have been planted at the Sunrise (Wenatchee) and Roza (Prosser) orchards, using two different rootstocks (M9-NIC29 and Geneva41). Trees were established as spindle, V trellis and to make bi-axis trees in randomized replicated blocks for each WA38/rootstock combination. With these two orchards, it will be possible to evaluate the territorial suitability of WA 38 in different levels of soil fertility. A training systems and rootstock trial for this newly released and promising variety will provide information to the growers of Washington on how to manage WA 38 and optimize fruit quality and profitability.
