| Description |
Inventors: Fredrick A. Bliss, Ali A. Almehdi, Theodore M. Dejong, Anne Gillen, Craig A. Ledbetter; The new `HBOK32` rootstock, a hybrid between two peach parents, is useful as a commercial under-stock for peach and nectarine cultivars. Utilization of adapted growth controlling rootstocks in commercial orchard situations reduces the height of the tree and the amount of wood pruned in the winter and summer, without compromising the quality of the fruit. This in turn increases the efficiency of various cultural operations such as pruning, thinning and harvesting by reducing the need for workers in the field to use tall ladders when carrying out these operations. |
