Researchers at Michigan State University (USA) provide a comprehensive analysis of the flower development of sour cherries. Numerous transcriptional studies have shown that the regulation of flower initiation in rosaceous species is significantly influenced by hormonal balance.

An overview of S-alleles of cultivated sweet cherries

Breeding

21 Dec 2023

Since then, information on the S-genotypes of sweet cherry cultivars has been constantly increasing. This information is very important for cherry growing, breeding, and breeding research. The S-genotypes of 1,700 sweet cherry accessions were recorded.

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.

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.

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

Breeding

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.
