Cherry tree named ‘PA7UNIBO’

Abstract

Variety Denomination PA7UNIBO is a novel cherry tree derived from a seedling of unknown cross which was planted at Vignola, Modena Province, Italy. The genus and species (cultivar) of PA7UNIBO is Prunus avium. It was initially propagated by grafting to root stocks of varying vigor and, after testing in districts and plantings of differing types, proved to have qualities for a promising new cultivar for the market.

Claims

Harvest: Maturity date range.June 10-June 25, approximately 26 days after Burlat and about 6 to 9 days after Bing. Optimum harvest dates of PA7UNIBO in Modena Province are June 15-20. Harvest date range (if different).Same as above. The diploid cultivar PA7UNIBO is self-fertile, with the allelic profile of S3S4. Fruit load and yield is high and constant, particularly in the presence of flying insects (e.g., bees, wasps, hornets, beetles, butterflies, etc.). PA7UNIBO possesses high fruit quality traits that hold steady through subsequent pickings, for at least 10 days. The method of propagation of the variety is represented by budding or grafting. Under observation during planting, growing and harvesting under normal cultural and growing conditions in Modena Province, Italy, PA7UNIBO has been tested against the following viruses: ACLSV, ApMV, PRNSV, PDV, CLRV, RpRSV, CNRMV, PPV, TBSV, LChV-1, LChV-1, SLRSV, ArMV, APLPV. The results were negative, i.e., PA7UNIBO was free from the above-mentioned viruses. Because of the outstanding and unique horticultural characters of the claimed plant, especially its long harvest period and large size, this cherry can be planted to extend the cultivar's season. Although this new variety of cherry possesses the above-described characteristics, it is to be understood that variations and fluctuations may occur in the magnitude and qualities due to changes in growing and climate conditions, irrigation, fertilization, pruning and pest control.
