Cherry variety: PA2UNIBO* Sweet Lorenz™

PA2UNIBO* Sweet Lorenz^® is one of the 7 varieties of sweet cherry belonging to the “Sweet” series. These varieties come from a breeding programme which began in the early 2000s at the Department of Tree Crops (now the Department of Agricultural and Food Sciences) at the Alma Mater Studiorum, with a precise “target”, i.e. to obtain six or seven varieties that could cover a harvesting period of at least 30-40 days, all with a “maximum” common denominator: fruits with excellent appearance, easily recognisable organoleptic qualities, obtained from trees with high agronomic performance and productivity.

• Tree: high vigour with semi-open canopy, good branching, standard bearing habit. Production mainly on the shoots and flowering buds at the base of the one-year old branches.
• Flowering: early, usually 1-2 days before Burlat. Self-compatible; allelic profile: S3S4; incompatibility group III (incompatible with Bing, Karina, Kristin, Lambert, Napoleon, Somerset, Star, Ulster, Selah, PA1UNIBO* Sweet Aryana® and PA4UNIBO* Sweet Valina®). Recommended pollinators: PA2UNIBO* Sweet Lorenz®; PA3UNIBO* Sweet Gabriel®; PA5UNIBO* Sweet Saretta®.
• Time of maturity: medium-early and uniform; harvest begins 8 to 10 days after Burlat depending on the year (same period as Celeste® Sumpaca*). The excellent ripening resistance on the plant ensures a harvesting window of over 15 days.
• Fruit: very large size (dominant calibre: 30 mm; average weight 12-14 g), cordiform, symmetrical, attractive. Medium thick skin, dark red shiny colour (scale 5 CTIFL code) covering the whole surface, tending to dark red-black and shiny when fully ripe (scale 6 CTIFL code). Slightly sunken suture line in the base area. Pink flesh with an excellent consistency, crispy, fleshy, juicy and aromatic, high quality, very sweet, good acidity content. Medium long, medium thick stalk. Medium small, freestone pit.
• Agronomic evaluation: early fruiting, both on weak (II-III year after planting out) and vigorous rootstocks (III-IV year); constantly high cropping. In years with heavy rainfall, the fruits have medium-low susceptibility to splitting compared to varieties of a similar period.
