Bavaria Saat meets the Challenges of the Future!

We at Bavaria-Saat are adjusting to the constantly changing requirements of the potato market with an extensive new breeding programme. Climate changes, for example, give rise to a demand for potato varieties which can give good results under dry climatic conditions. Special attention is also given to developing varieties with a high resistant a level to viruses.

By using complex maintenance cultivation methods it is possible to maintain the quality of the varieties.


The main opjective of the Bavaria-Saat is to breed robust varieties in accordance with the following criteria:

  • High quality food varieties for all harvests
  • Varieties for processing purposes
  • High-yield robust starch potatoes

The following spectrum of resistance categories are of special consideration when selecting varieties for breeding purposes:

  • Broad nematode resistance
  • Resistance to potato wart disease
  • Virus resistance
  • Late blight resistance
  • Resistance to storage diseases

Testing for resistances is partly carried out in cooperation with the Bavarian Central Authority of Agriculture (LfL) in Freising/Weihenstephan.

The breeding material is planted outdoors in light soil for the first three years, giving a good basis for selection regarding scab and tolerance in dry conditions.

The cultivation scheme used at Bavaria-Saat:

1300 – 400 Crosses
280.000 – 100.000 Greenhouse seedlings
360.000 – 70.000 Single plants
43.000 – 4.000 A – clones
5500 – 600 B – clones
680 – 150 C – clones
730 – 50 D – clones
815 – 20 E – clones
92 – 4 Official Classification trial 1, Bundessortenamt
101 – 3 Official Classification trial 2, Bundessortenamt
111 – 2 Authorization of variety following examination by official standards


The extent of the maintenance breeding we carry out depends on the market significance of a particular variety. Bavaria-Saat varieties are propagated exclusively using  in-vitro – cultivation methods.

This work is also done in cooperation with the Bavarian Central Authority of Agriculture. The in-vitro method ensures a completely bacteria and virus-free propagation of new plant material.

Potato Maintenance Cultivation Scheme:

1Cultivation of in-vitro plants under sterile conditions. Greenhouse cultivation of M1 tubers
2tubers cultivated in tunnel or under gauze
3tubers – cultivation under gauze harvest as pre-basic seed
Years followingfollowing – Production of seeds class S/SE/E in selected production farms in healthyregions e.g. costal regions in northern Germany

During the first three years of the maintenance breeding process virus infections by  aphids are prevented 100% mechanically. This is done over an area now covering approx. 4.000 m2 gauze tunneling and 14 hectares of gauze sheeting divided between the 4 Bavaria-Saat partner farms. This method considerably reduces the use of insecticides.
