Seven new cultivars have already been released: Narana, Swing® PiSue 192, Habunt, Areko, Polka, Aria® PiSue 161, and PiSue 177. Nineteen new promising breeding clones are currently under multi-site testing and approximately 100 clones are in stage II evaluation.

How to increase fruit size? By silencing growth-limiting genes


29 Nov 2023

In fruits in which PavKLUH was silenced, a decrease in fruit size was observed, due to less expansion of the mesocarp cells. By identifying a new gene encoding for PavKLUH, PavRAV2, a transcription factor capable of physically interacting with the PavKLUH promoter, was selected.

A study on cherry genome reveals the genes responsible for fruit quality

Breeding Quality

27 Nov 2023

23 fruit quality characteristics were evaluated over a period of 2-6 years. The collected germplasm was characterised by genotyping-by-sequencing. A genome-wide association study was conducted using SNP (single nucleotide polymorphism) coverage collected.

Decade-long study identifies more than one million polymorphisms on cherry genome


24 Nov 2023

Phenotypic diversity was assessed from 2012 to 2020, revealing significant variability in several traits. A total of 1,767,106 single nucleotide polymorphisms were discovered, providing a detailed genetic map.

More than 250 crosses have already been made, using a genetic collection of over 50 varieties of diverse origins. The best ones are then grafted onto Maxma Delbard® 14 Brokforest for a second evaluation. Today, more than 80 grafted selections will go into production in 2024/25.

Rootstocks modulates the gene expression in sweet cherry crop
