Researchers explain the regulatory mechanism of dormancy genes

Breeding

30 Dec 2024

The aim of the work presented in Cáceres (Spain) was to study the relationship between the expression of PavDAM genes throughout the entire winter dormancy period, that is, from the onset of dormancy until the beginning of bud break (from October to February).

From resistance genes to the development of new varieties of sour cherries

Breeding

27 Dec 2024

The objective of this research (conducted at the Institute for Breeding Research on Fruit Crops in Dresden, Germany) was to use computational methods and bioinformatics tools to investigate the presence and distribution of resistance genes in the two subgenomes of sour cherry.

Cherry cracking is also due to hormonal imbalances

Breeding

24 Jun 2024

Researchers from several Chinese institutes and universities summarised the progress made worldwide in understanding the effects of endogenous gibberellin and abscisic acid content in fruit and exogenous hormone treatments on fruit cracking.

Genome-wide association studies (GWAS) identify genes related to cherry size

Breeding

13 Mar 2024

11 and 12 candidate genes related to fruit size and cracking-related traits, respectively, were identified. The researchers also identified several candidate genes involved in phytohormone, calcium and cell wall metabolisms.

French genome-wide association studies identify 65 SNP-trait associations

Press review

07 Mar 2024

Using 116 sweet cherry accessions, researchers analysed 23 agronomic fruit quality traits. The research uses genotyping by sequencing (GBS) to identify genetic markers associated with improved fruit quality.

Pairwise: US start-up relies on CRISPR technology to create stone-free cherries

Press review

27 Feb 2024

The company is studying how to produce cherries without stone. We are therefore working on modifying the architecture of the plant,' says Tom Adams, CEO and co-founder of the company, 'so that it can be grown in a greenhouse like a blueberry, thus expanding the production area.

Blooming date is decided (at genetic level) before winter dormancy

Breeding

02 Jan 2024

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.

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.
