1 Durable disease resistance in forage and turf grasses "DURGRASS"
Proposal for a new Action Durable disease resistance in forage and turf grasses "DURGRASS" Roland Kölliker Molecular Ecology, Agroscope Reckenholz-Tänikon Research Station ART 8046 Zurich, Switzerland

2 DURGRASS – a new COST Action
to stimulate a rapid move towards durable disease resistance in forage and turf grasses through: detailed knowledge on host-pathogen interactions an efficient pipeline for identifying and exploiting resistance genes and alleles science based measures for integrated disease management Durable disease resistance in forage and turf grasses "DURGRASS" | DC Hearing , Tallinn Roland Kölliker | © Agroscope Reckenholz-Tänikon Research Station ART

3 Forage and Turf Grasses
Permanent and temporary grasslands Cover more than 50% of Europe's farmed landscape Provide various ecosystem services Form attractive landscapes Forage grasses account for a large proportion of the annual production of beef and milk (value > € 70 billion (source: Eurostat)) Turf grasses are the main component of sports fields and recreational lawns Forage species: lolium, fescue, orchardgrass Turf species: fine and creeping bentgrass (agrostis tenuis and stolonifera), smooth stalked meadow grass (poa pratensis), lolium, fescue Golf courses account for at least 300‘000 ha in Europe Durable disease resistance in forage and turf grasses "DURGRASS" | DC Hearing , Tallinn Roland Kölliker | © Agroscope Reckenholz-Tänikon Research Station ART

4 The Problem Epidemic appearance of serious diseases
At least 20 different fungal, bacterial and viral pathogens Forage grasses Crown rust, bacterial wilt, leaf spots Turf grasses Microdochium patch, pink snowmold, anthracnose At least 20 different diseases described in forage and turf grasses Puccinia coronata fsp lolii Xanthomonas translucens pv graminis Bipolaris sorokiniana, Drechslera siccans Microdochium nivale Colletotrichum graminicola Microdochium bolleyi Durable disease resistance in forage and turf grasses "DURGRASS" | DC Hearing , Tallinn Roland Kölliker | © Agroscope Reckenholz-Tänikon Research Station ART

5 The Consequences Grassland agriculture Turf grass management
Reduced yield and quality (30-80% for crown rust) Risk of reduced animal health through toxins  No pesticide applications >> economic losses Turf grass management Reduced aesthetic quality of lawns and turf Reduced playing quality of sports fields  Intensive application of pesticides >> environmental pollution Durable disease resistance in forage and turf grasses "DURGRASS" | DC Hearing , Tallinn Roland Kölliker | © Agroscope Reckenholz-Tänikon Research Station ART

6 The Solution Improved and durable disease resistance in forage and turf grasses Although individual aspects of host-pahogen interactions have been studied, there is no systematic strategy on how to obtain and maintain durable disease resistance in forage and turf swards.

11 DURGRASS - Organisation
WG II: Genetics of host resistance WG I: Diversity and ecology of pathogen populations WG III: Integrated disease management Durable disease resistance in forage and turf grasses "DURGRASS" | DC Hearing , Tallinn Roland Kölliker | © Agroscope Reckenholz-Tänikon Research Station ART

12 Objectives WG I Increase knowledge on phylogeography and evolution of pathogens with regard to increased globalisation and climate change Establish characterised European collections of prevailing pathogen isolates and provide access through a public database Establish guidelines for the use of pathogen isolates for phenotyping of plant material in resistance breeding programmes Durable disease resistance in forage and turf grasses "DURGRASS" | DC Hearing , Tallinn Roland Kölliker | © Agroscope Reckenholz-Tänikon Research Station ART

13 Objectives WG II Establish comparative and functional genomics tools and platforms for unravelling genetic control of disease resistance Increase knowledge regarding allelic diversity of resistance genes Develop methods and tools for transferring innovations and technologies rapidly into improved procedures for the European plant breeding industry Durable disease resistance in forage and turf grasses "DURGRASS" | DC Hearing , Tallinn Roland Kölliker | © Agroscope Reckenholz-Tänikon Research Station ART

14 Objectives WG III Establish improved and standardised protocols for an efficient use of disease resistance in plant breeding programs by phenotypic as well as marker assisted selection Establish guidelines and methods for integrated disease management in grassland agriculture and turf grass management Durable disease resistance in forage and turf grasses "DURGRASS" | DC Hearing , Tallinn Roland Kölliker | © Agroscope Reckenholz-Tänikon Research Station ART

15 Key Deliverables Action website Databases and technical protocols
General and specific information on Action achievements Thematic mailing lists and discussion forums Databases and technical protocols Characterised collections of pathogens relevant for grassland agriculture and turf grass management Genes and QTLs conferring resistance to grass pathogens Durable disease resistance in forage and turf grasses "DURGRASS" | DC Hearing , Tallinn Roland Kölliker | © Agroscope Reckenholz-Tänikon Research Station ART

16 Key Deliverables Workshops with published proceedings
Importance of pathogen diversity and evolution Molecular genetic tools in grass breeding Breeding strategies and integrated disease management Scientific articles and technical documents Efficient use of pathogen isolates in grass breeding Enhanced breeding by marker assisted selection Practical management guidelines Durable disease resistance in forage and turf grasses "DURGRASS" | DC Hearing , Tallinn Roland Kölliker | © Agroscope Reckenholz-Tänikon Research Station ART

17 Key Deliverables Interdisciplinary Training Schools
Cultivation and phenotyping of pathogens Application of molecular genetic tools Short Term Scientific Missions Book on durable disease resistance in forage and turf grasses Durable disease resistance in forage and turf grasses "DURGRASS" | DC Hearing , Tallinn Roland Kölliker | © Agroscope Reckenholz-Tänikon Research Station ART

18 DURGRASS Will produce for the first time a tight network of scientists working on durable disease resistance in forage and turf grasses using technologies, tools and ideas from all areas of research Will enable strong collaboration between research institutes and SMEs, which are important partners of this network Durable disease resistance in forage and turf grasses "DURGRASS" | DC Hearing , Tallinn Roland Kölliker | © Agroscope Reckenholz-Tänikon Research Station ART

19 DURGRASS Is unique in its aims and goals and no comparable European research programme exists. Will make efficient use of knowledge generated in earlier European programmes such as SAGES or GRASP Will establish links and exploit synergies with European projects such as TRITIGEN, EuroDIVERSITY or Triticeae Genome Durable disease resistance in forage and turf grasses "DURGRASS" | DC Hearing , Tallinn Roland Kölliker | © Agroscope Reckenholz-Tänikon Research Station ART

20 DURGRASS Will enable rapid increase in plant health, benefit animal and human health, sustain competitive grassland agriculture in face of an increasing future demand and reduce environmental pollution Durable disease resistance in forage and turf grasses "DURGRASS" | DC Hearing , Tallinn Roland Kölliker | © Agroscope Reckenholz-Tänikon Research Station ART
