| Description |
As part of a statewide organized prune rootstock evaluation, ten marianna rootstocks (Prunus cerasifera Ehrh. x P. munsoniana) derived from open pollination of ‘Marianna 2616’(M series) were planted in 1987 and evaluated at four commercial orchard locations in California (Tehama, Butte, Sutter, and Merced counties) with ‘Improved French’ prune as the scion. These rootstocks were compared to three standard rootstocks: ‘Marianna 2624’, myrobalan seedling (P. cerasifera Ehrh.) and ‘Myrobalan 29C’. Leaf potassium (K) and nitrogen (N), tree growth, fruit production and fruit quality were measured. Selection M40 in particular had high leaf N, high leaf K (equal to ‘Marianna 2624’ and better than the myrobalan standards), higher yield efficiency per tree, fruit size, drying characteristics, and few root suckers when compared to the three standard rootstocks. M40 is being considered for patent and release by the Pomology Department at the University of California, Davis. Selection M58 had the highest yield efficiency of any tested rootstock. Several selections had characteristics that would make expanded planting worth considering.
Selection M-30 had high leaf K (potassium) concentrations, but it was never found to have consistently higher leaf K than the standard M2624. M-30 is a vigorous tree with high dry yields, but as yield goes up fruit size decreases and the yield efficiency is not better than M2624. |
