Centro Fruticultura Sur leads collaboration on a rootstock genetic improvement program

Rootstocks

13 Dec 2023

As part of this project, 3 demonstration plots were created between 2021 and 2022 at the Universities of Concepción, La Frontera and Austral de Chile, with 10 cherry rootstock selections, plus 2 commercial controls: Gisela 12 and Colt.

Interspecific hybrids – as new sources for sweet and sour cherry breeding

Breeding

11 Dec 2023

At Dresden-Pillnitz interspecific crosses and backcrosses have been carried out over the last 20 years. The aims of this breeding program are to develop genotypes with new fruit characteristics and a higher level of resistance to biotic and abiotic stress.

Sweet and sour cherry varietal innovations and breeding program in Hungary

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

Breeding

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.

Major targets for new varieties include large fruit size, firmness, early ripening, self-fertility, and disease resistance. Crosses are made in the orchard and increasingly in the hoop house which extends the crossing season and provides frost protection.
