10 Feb 2025

"In the last 13 years we have produced an average of 4700 hybrids per year. We collect 80000 seeds, out of which 60000 come from ‘controlled’ open pollinations. The largest families have 250-300 hybrids" says Dr. José Manuel Donoso of INIA Rayantué.

Meda™: new early and intermediate cherry varieties in Europe

Varieties

04 Feb 2025

Meda™ varieties have been evaluated in Europe for three seasons now. All have been selected with a minimum of 35-40 days post-harvest. Meda™'s is the only breeding programme that has used postharvest as a selection filter.

INIA bets on Chile Chico: over 200 hectares and 5 varieties to improve Chilean supply

The challenge for regional production is to distinguish itself on the market through quality, as late production is no longer a differentiating factor. To date, the region has 244 hectares dedicated to cherry production in the Chile Chico Valley.

Cracking susceptibility of full-sibs of a cross of a cracking tolerant and cracking susceptible sweet cherry: relation to cuticle characteristics, microcracking and Calcium

Breeding

20 Jan 2025

The objectives of the study was to phenotype a segregating population of sweet cherries for selected key traits of the Zipper model and for their susceptibility to cracking, for which the QTLs for cracking susceptibility were established earlier.

Dwarfing rootstocks show epigenomic differences in the grafted cultivar

Rootstocks

16 Jan 2025

The study conducted at the University of Guizhou (China) aimed to investigate the impact of the dwarfing rootstock ‘Pd1’ (Prunus tomentosa) on sweet cherry ‘Shuguang2’ shoots. To achieve this goal, morphological observations were conducted.

Examination of self-(in)compatibility in sour cherry genotypes developed at Serbian Fruit Research Institute, Cačak

Breeding

16 Jan 2025

Despite the fact its manifests similarly to other Rosaceae species, GSI in sour cherries is more complex due to tetraploidy and the presence of pollen-part and stylar-part mutants that cause genetic changes at S-locus.

Cherries and patents: DNA screening can fight legal disputes

Breeding

10 Jan 2025

According to a lengthy legal dispute between the Canadian government and some fruit companies in Washington, several forms of DNA screening, years of field experiments, and a federal judge's ruling are required.

The role of PavSPL genes in sweet cherry development

Breeding

09 Jan 2025

A recent Chinese study analyzed their role in sweet cherry (Prunus avium). The findings showed that the seasonal expression of PavSPL genes varies throughout the plant's annual cycle, particularly during the post-dormancy recovery period.

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).
