Genome sequence of the morelle decoded

Research team uses novel technologies to investigate the complex genetic material of the sour cherry variety and draw conclusions about the origin of the fruit species

26-Mar-2024 - Sour cherries (Prunus cerasus L.) have a very large (tetraploid) genome. This is due to the fact that in the course of evolution, i.e. on the way from the wild ancestors to today's varieties, the genomes of the parents have combined. The sheer size and complexity of the genome has so far made it ...

Green, sweet and crisp - New apple variety Pia41 approved

The apple bred at the Julius Kühn Institute receives variety protection

05-Sep-2023 - A green-yellow skin, juicy-crisp flesh and a sweet taste with intense aroma, these are the salient features of Pia41. The apple has now been granted plant variety protection. It was bred in Dresden-Pillnitz at the Julius Kühn Institute (JKI). In addition to the above-mentioned properties, the ...

Red Riesling originated from White Riesling – not vice versa

Berry color locus of the Red Riesling variant located on the chromosome set of the white-berried parent White Heunisch

11-May-2022 - The ancestors of today's cultivated grapevine varieties as well as almost all wild Vitis species have dark berries at the time of ripening. For a long time, breeders and scientists therefore assumed that the white-berried grapevine variety 'White Riesling' (RW), commonly referred to as ...

First resistance to wheat dwarfing virus discovered

Julius Kühn Institute researchers identify 14 gene loci that could be used to breed new virus-resistant wheat varieties

20-Apr-2022 - If the wandering sand cicada (Psammotettix alienus) bites a wheat plant to drink plant sap, the consequences can be fatal: Along with its saliva, the cicada can transmit Wheat Dwarf Virus (WDV). Depending on the age of the plant at the time of infection, yields drop by at least 30 percent, and ...

Fight against the grape moth

13-Aug-2019 - Vine protectors at the JKI want to develop an egg deposition card that can be read on a smartphone and can be used to better predict the occurrence of the wine pest. In this way, grape mothers could be combated even more specifically in the future and pesticides could be saved in viticulture. ...
