Climate change and sustainability are driving forces for changing varieties in a traditional market

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

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.

XIII. International Symposium on Grapevine Breeding and Genetics 10.7. until 17.7.2022

Note: the symposium will be held without the participation of the ISHS

in Landau/Pfalz, Germany

The JKI, Institute for Grapevine Breeding Geilweilerhof is proud to host the XIII. International Symposium on Grapevine Breeding and Genetics in 2022.

Back in the 1970s, Prof. Alleweldt, then head of the Institute for Grapevine Breeding Geilweilerhof in Siebeldingen, Germany, initiated the idea of an international conference as a forum for the dynamic field of grapevine breeding at the time. The idea was to initiate a conference series, that every four years brings together leading scientist in grapevine genetics and breeding at different winegrowing places around the world.

The first meeting took place in September 1973 at Geilweilerhof under the name „International Symposium on Vine Breeding“. Following symposia were held in Bordeaux, Davis and Verona, Siebeldingen, Yalta, Montpellier, Kecskemet, Udine, Geneva, Beijing, and Bordeaux. The 360 participants of the GBG2018 voted for Germany to host the next conference. Now after almost half a century the Congress is coming back again to Geilweilerhof.

The conference takes place in the historic Art Nouveau „Festhalle“ in Landau next to the southern wine route in Germany in the beautiful wine region „Palatinate“.

The conference will highlight current research topics in eight sessions and poster presentations on grapevine

  • genetic resources
  • phenotyping
  • biotic stress
  • abiotic stress
  • grape and wine quality
  • big data management
  • breeding
  • novel technologies

A technical tour will comprise excursions to JKI Geilweilerhof, DLR in Neustadt an der Weinstraße, and brings you to experience local wineries and their outstanding wines.

The conference dinner will be located in Annweiler am Trifels, towered by Trifels castle, one of the most important castles of the Middle Ages, where Richard the Lionheart the King of England was imprisoned 1193/1194. Meet your colleagues from all over the world in a picturesque landscape full of historic places. Post-conference tours will lead you to famous wine regions of Germany.

We hope you take the opportunity to make a fresh start after the pandemic and join the conference.

We are looking forward to see you soon in our famous region!

New generation of pathogen-resistant wine grape varieties in Hungary – by Dr. Pal Kozma

Summary of an article from Borászati Füzetek magazine – Hungary
written by Dr. Pal Kozma

There is a strong societal demand and expectation for environmental and health protection. The EU plans to take further decisive steps to limit the use of environmentally harmful chemicals in agriculture. One of the prerequisites for the development of environmentally friendly, profitable and competitive viticulture is the creation and introduction of varieties resistant to the main pathogens, while maintaining good quality. The genetic results of the last decades make it possible to achieve these goals. As a result of the breeding activities of the Research Institute of Viticulture and Oenology in Pécs, 6 white and 1 red varieties have received state approval and another 10 white and 3 red varieties are in the certification process. Community plant variety rights were granted for two innovative resistant grape varieties.

New information brochure "Fungus-resistant grape varieties" from the WBI Freiburg

The Freiburg State Viticulture Institute has published a new brochure on its fungus-resistant new varieties. The brochure is now available for download on the WBI website (https://wbi.landwirtschaft-bw.de/pb/,Lde/Startseite/Fachinfo/Pilzwiderstandsfaehige+Keltertraubensorten). The brochure is also available in English, French and Italian.

Furthermore, the WBI points out that the Souvignier Gris variety is a cross between Seyval Blanc x Zähringer. Cabernet Sauvignon and Bronner were originally assumed as parent varieties, and this information can still be found in some publications. However, a genome analysis of the seedling stock commissioned by the Freiburg State Viticulture Institute in 2019 clearly showed that the mother variety is Seyval Blanc and the father is the Zähringer variety.

Fungus-resistant grape varieties play a central role in the increasingly ecological orientation in viticulture. With the results of its resistance breeding, the Freiburg State Viticulture Institute is making a significant contribution to the protection of nature, profitability and the winegrowers in terms of sustainable vineyard management. Many of the new Freiburg breeds are also met with great interest outside of Germany and are now cultivated in over 30 countries. This makes the WBI one of the world's leading research institutions in vine breeding.


I am happy to answer any additional questions.

Many thanks and best regards

What's new in vine breeding!

The result of our first online meeting of the vine growers: the exchange of experience and information was very much in favor of everyone, and PIWI International is increasingly available here. The demand for PIWI vines is increasing enormously. More information is desired here, also about the right use in the right place.

We'll start compiling some interesting links here as a result of our meeting:

PIWIS in the growing year 2021 by Wolfgang Renner (AT)

Black rot and KEF? - Not a real challenge!

According to multiple applications in 2021, PIWIS will occupy an area of around 145 hectares in Styria. This corresponds to 2.9% of the entire Styrian vineyard area. By far the most common varieties are Muscaris and Souvignier gris. As in previous years, current experiences from experimental cultivation are presented here in a condensed form.

* KEF = cherry vinegar fly

Weather 2021

Last winter was characterized by a consistently good water supply. A very cold April was followed by a cool May. The latest shoot of the vines in the last 25 years was the result. Both months were also characterized by a high number of rainy days. The very warm and dry months of June and July were followed by a comparatively cool and humid August. September was again one of the warmer ones compared to previous years and turned out to be a special “ripening accelerator”.

Generally speaking, the conditions for fungal diseases in 2021 were not the best. Of course, that makes the winegrowers happy! In the crucial phase from May to July there were only 37 rainy days in the Leutschach branch (52 in 2020, 48 in 2019). Only 20% of the entire time there was leaf wetness *, which is significantly less than in the previous vegetation years 2020, 2019 and 2018 with approx. 25% each. All of this explains the relatively low black rot infection pressure in the past season.

Plant protection measures 2021

All PIWI varieties were treated against fungal diseases with the same frequency and intensity. Due to the successive increase in black rot (Guignardia bidwellii) in recent years, a stricter plant protection regime has been prescribed from the 5-leaf stage. From the 5-leaf stage to post-flowering, five treatments were carried out 7 to 12 days apart. Because of the increasing oidium pressure, a separate sulfur injection took place on August 10th.

PIWI varieties at a glance - results in the rainy year 2021

PIWI vines have been around for over a hundred years. Only a few were able to establish and hold onto. While the time of the regent seems to have expired, Léon Millot or Maréchal Foch are still being grown. But in times of ecological agriculture and climate change, more and more winegrowers are interested in new varieties that spring up like mushrooms. Piwi pioneer Edy Geiger provides an overview.
