Advances and applications of plant phenotyping in viticulture

Quantitative assessment of the plant phenotypes provide the vital link between genetic information and biological structure and function which is needed to improve plant performance, tolerance to biotic or abiotic stress or quality related traits. Due to technical advances within the last decade genomic data became easily accessible, but the generation of phenotypic information is not keeping pace with the explosion in available genomic information. The lack of reliable and available phenotypic data limits the possibilities to identify associations between phenotypic and genotypic data. This phenotypic gap is a major challenge in biological understanding of plant processes and their translation into practical application. Specifically phenotyping of perennial plants such as grapevine under field conditions represents challenge for quantitative non-invasive assessment of a variety of traits.

In this workshop, we will focus on discussing the requirements and challenges in viticulture where relevant high-throughput field phenotyping platforms may support quantitative assessment relevant traits over vast areas. Specifically, addressing these challenges requires interaction within the community. The EU funded project EPPN2020 provides access to some plant phenotyping facilities in Europe (https://EPPN2020.plant-phenotyping.eu/), while the ESFRI listed project EMPHASIS aims at a synergistic development and long-term operation of phenotyping infrastructure in Europe (https://emphasis.plant-phenotyping.eu/) by developing infrastructures and providing access for multi-scale phenotyping to analyze genotype performance in diverse environments and quantify the diversity of traits. One of the key elements of EMPHASIS is the development of well-instrumented field sites with high-resolution recording of the environmental conditions (including abiotic and biotic) and detailed imaging carried by proximal or remote sensing systems on airborne or ground based systems linked to relevant information systems.

To make progress within the grapevine community structures and common goals need to be defined. Uli Schurr from Forschungszentrum Jülich (Germany) will point out the possibilities in Europe to establish infrastructures to intensify phenotyping. Katja Herzog from JKI Institute for Grapevine Breeding Geilweilerhof will bring up some examples and summarize some possible needs. Very important in all this is the data organisation and data integration which will be addressed by Mario Pezzotti, form University Verona and representative of COST CA17111 INTEGRAPE: Data integration to maximise the power of omics for grapevine improvement (http://www.cost.eu/COST_Actions/ca/CA17111)

For organizational reasons, you are kindly requested to express your interest in participating in the phenotyping workshop by sending a brief email to zr@julius-kuehn.de before 1st  July 2018.

Preliminary Programme

Advances and applications of plant phenotyping in viticulture

Tuesday, July 17th 2018 from 5 to 7 pm

1. Impulse presentations (60 Min.):

Uli Schurr, FZ Jülich Introduction of EMPHASIS and EPPN2020

Katja Herzog, JKI; Germany Examples of phenotyping grapevines

Mario Pezzotti, Uni Verona and representative of COST CA17111 INTEGRAPE: Data integration to maximise the power of omics for grapevine improvement (http://www.cost.eu/COST_Actions/ca/CA17111)

2. Integration of the community and the role of EMPHASIS (60 Min.):

Discussion of a memorandum of understanding will be prepared and distributed prior to the Symposium. It should - problem driven - summarize the main lines for grapevine phenotyping:

  • Information on available infrastructure within the community such as:
    • Sensors and the traits that can be evaluated
    • Platforms to be used in the field/greenhouse/laboratory and the traits that can be evaluated
    • Demand …
  • Defining traits/research questions of practical relevance in a prioritized manner such as
    • Biotic and abiotic stress
    • Yield
    • Product quality
    • management
  • Establishing experimental field sides in different climatic regions with a core set of common genotypes (Who is establishing a side? What are the common genotypes how many?)
  • Making use of existing gene banks for phenotyping (low cost phenotyping)
  • Development of automation pipelines (software (GUI) and hardware) for monitoring traits by not expert users
  • Development of standards (on reference data and sensor data)
