Seminis Lettuce Seeds Confirmed as Resistant to new Downy Mildew Bremia Race

We are delighted to confirm that at least four of the iceberg varieties in our current commercial portfolio are confirmed as resistant to the recently announced new Downy Mildew Bremia Race Bl: 36EU. 
 
Agility Agriculture supply Seminis branded lettuce varieties which offer broad resistance patterns.  We are delighted to confirm that these varieties have been tested against this new race and the following varieties have been confirmed as resistant along with all material that we currently have in test:
 
Iceberg 
 
Poetic -  has a flat, round head shape and flat ribs, making it an ideal variety to grow throughout the year.
Tassic - a mid-maturing dual use variety that suits both whole head and processing markets and produces high quality heads.
Affic - an ideal whole head iceberg lettuce that produces uniform high quality heads and can be used for the majority of the year’s production.
SV3413LC - a compact, early maturing variety with excellent disease resistance, for summer production
 
The International Bremia Evaluation Board Europe (IBEB-EU) has collected more than 300 Bremia isolates in European lettuce in 2018 and compared them with the 500 isolates found in 2017.  One race already spotted in previous years appeared to have spread over larger distances and was isolated in various centres of lettuce production.  The IBEB-EU has announced this isolate as new race Bl: 36EU.
 
BL: 36EU is widely spread in Europe and is found in France, Germany, the Netherlands, Italy, Austria, Switzerland and Scandanavia.  This race may be described as a more virulent variant of Bl: 34EU, able to break one additional resistance source.

Agility Agriculture advocates an integrated approach to disease control; resistant varieties are a large part of this, however crop protection agents and hygiene measures are also important to help prevent the development of new Downy Mildew races.  Appropriate hygiene practices, such as the removal of debris and diseased plants will always reduce the spread of Bremia in lettuce crops.  Resistance to these strains does not mean that a variety offers total resistance to Bremia and should not be understood as a full insurance against Bremia.
