(Siebeldingen) Jochen Bogs was awarded the Peter Morio Prize 2022 for his outstanding scientific contribution to vine breeding. Prof. Bogs teaches at the wine campus in Neustadt, among other things, on the physiology and biochemistry of the vine and grapes, biotechnology, vine breeding and vine nutrition. His numerous publications speak for his excellent scientific networking in Germany and abroad. His expertise is valued worldwide. The prize is awarded by the community of sponsors and friends of the Geilweilerhof Institute for Vine Breeding. The Institute for Vine Breeding at the Geilweilerhof site in Siebeldingen belongs to the Julius Kühn Institute (JKI), the Federal Research Institute for cultivated plants. The award was presented on June 3rd at the association's annual general meeting.

In his laudatory speech, the head of the JKI vine breeding and managing director of the association, Prof. Dr. Töpfer, Prof. Bogs for his achievements. Jochen Bogs is currently researching the mechanisms with which fungus-resistant grape varieties (PIWI) defend themselves against harmful fungi. Another focus of his research is the ingredients of the berries and their influence on the quality of the grapes. He is currently working with the vine breeders and vine protectors of the JKI in the VITIFIT project: "Healthy vines in organic viticulture through research, innovation and transfer" together.

Many milestones have been reached - the VITIFTI joint project has now been running for almost three years.

VITIFIT – Status quo in the third year of the project

The joint project VITIFTI has now been running for almost three years. The focus is on the pathogen of downy mildew, Plasmopara viticola. In the Freilandsaion 202, more demo wineries are to be integrated. The review of innovative approaches to copper minimization is one of the core elements of the VITIFIT project. Prof. Dr. Beate Berkelmann-Löhnertz and Dipl-Ing. Stefan Klarner, Hochschule Geisenheim University, show the current project status.

… PIWIs in focus 

The use of PIWIs in organic viticulture practice will be the most effective way of reducing copper applications in the future, because the number of treatments can be reduced to three to four with PIWIs. So, growing PIWIs offers great potential for copper minimization...

Divico wines blended with Pinot noir - good quality and intense colour

Divico, Agroscope's new disease-resistant grape variety, is valued for the quality of the wines made from it. Assemblage trials with the Pinot noir variety have shown that Divico is suitable for correcting color intensity.

With an area of almost 3900 ha in 2020, Pinot noir is the most commonly cultivated variety in Switzerland. It is widespread in all wine-growing regions north of the Alps. The good reputation is based on the fine and typical bouquet of its wines, which is characterized by fruity notes and a good structure as well as very delicate and velvety tannins. Visually, the color intensity is sometimes judged to be a bit weak. Dyer grapes such as Dakapo and Dunkelfelder are therefore cultivated in Switzerland, and their wines are used in low-percentage blends to improve the color of Pinot noir. With the first red grape variety developed by Agroscope and approved in 2013, which is resistant to downy mildew and powdery mildew as well as gray mold, another variety is available that is suitable for this purpose.

A cool climate perspective on grapevine breeding: climate change and sustainability are driving forces for changing varieties in a traditional market

Abstract
A multitude of diverse breeding goals need to be combined in a new cultivar, which always forces to compromise. The biggest
challenge grapevine breeders face is the extraordinarily complex trait of wine quality, which is the all-pervasive and most
debated characteristic. Since the 1920s, Germany runs continuous grapevine breeding programmes. This continuity was
the key to success and lead to various new cultivars on the market, so called PIWIs. Initially, introduced pests and diseases
such as phylloxera, powdery and downy mildew were the driving forces for breeding. However, preconceptions about the
wine quality of new resistant selections impeded the market introduction. These preconceptions are still echoing today and
may be the reason in large parts of the viticultural community for: (1) ignoring substantial breeding progress, and (2) stick-
ing to successful markets of well-known varietal wines or blends (e.g. Chardonnay, Cabernet Sauvignon, Riesling). New is
the need to improve viticulture ́s sustainability and to adapt to changing environmental conditions. Climate change with its
extreme weather will impose the need for a change in cultivars in many wine growing regions. Therefore, a paradigm shift
is knocking on the door: new varieties (PIWIs) versus traditional varieties for climate adapted and sustainable viticulture.
However, it will be slow process and viticulture is politically well advised to pave the way to variety innovation. In contrast
to the widely available PIWIs, competitive cultivars created by means of new breeding technologies (NBT, e.g. through
CRISPR/Cas) are still decades from introduction to the market.
