WG1 - Genetic resources and rootstock breeding

Leader: Andrew J. Thompson, Cranfield University, UK

Co-Leader:  Halit Yetisir, University of Erciyes Melikgazi, Turkey

Presentation of WG leader during Final Conference in Pula

The task will define the current genetic variability existing in each vegetable species, as well as the existing breeding programs.

Specifically, this WG will collect:

  • information on germoplam available for each selected vegetable species;
  • information on commercial rootstocks used in different European Countries and non-European countries:

botanical classification, common name, origin, history, diffusion, characteristics (eg. vigor, biotic/abiotic stress resistance), environmental and cultural conditions in which is used (eg. open field, greenhouse conditions, soil vs. soilless culture), and rootstock-scion combinations and grafting method most commonly used;

  • information on ongoing breeding programs for developing new rootstocks.

These information can be easily collected by books and articles already published and by interview questionnaire to seed companies, nursery companies, vegetable grower associations, and institutions.

The results of this work will enable the participants and end users to develop a clear overview of the status of vegetable grafting in some European and non-European countries, and the information provided will be useful to identify bottlenecks, limitations and needs for different species, and to evaluate the potential of new rootstocks and graft-able species.

Moreover, based on agronomic, physiological and genetic information available and generated in WGs1-4, this WG will also identify classical and biotechnological breeding strategies to generate new rootstocks and to improve desirable traits in crop varieties of selected species. Efforts will be focused on individual rootstocks that are graft-compatible with two or more different species.

 

WG2 - Rootstock-scion interactions and graft compatibility

Leader: Jan Henk Venema, University of Groningen, The Netherlands

Co-Leader: Ian C. Dodd,
Lancaster University, UK

Presentation of WG leader during Final Conference in Pula

This WG will deal with chemical compounds (eg. hormones, nutrients, proteins, RNAs) and hydraulic signalling between root and shoots.

Specifically, this WG will collect:

  • information on the molecular, biochemical and physiological studies related to root-shoot communication;
  • information on the factors affecting grafting compatibly.

This information can easily be collected by books and articles already published and by seed companies and nursery companies. Moreover, information can be obtained by ongoing research activities carried out by WG members.

The WG will permit to define major physiological and genetic determinants of root and shoot development and compatibility of rootstock-scion for each vegetable species. Integrating the information provided by the WG1 with the activity of the WG2 will be possible to identify the best genetic resources to be used for developing new rootstocks with high grafting compatibility with the most widely spread cultivars of selected vegetable crops. Thus, the results of this WG will be useful for future breeding programs aiming to develop new rootstocks (WP1).

 Outcomes of the Industry questionnaire: inventarisation of main crop-related rootstock problems

 

WG3 – Rootstock-mediated resistance to biotic and abiotic stresses

Leader: Dietmar Schwarz, Institute of Vegetable and Ornamental Crops, Germany

C
o-Leader: Roni Cohen, ARO, Newe Ya'ar Research Center, Israel

This WG will define the current status of knowledge about rootstock-mediated crop improvement to attenuate the impacts of biotic, abiotic and combined stresses, and on the improvment of resource use efficiency (eg. water, nutrients) by grafting.

Specifically, this WG will collect:

  • information on the main biotic and abiotic stresses for the selected vegetable crops in different countries;
  • information on research activities aimed at studying the rootstock responses to biotic and/or abiotic stresses and providing insight into the mechanisms underlying these responses;
  • information on research activities on the effects of rootstocks on resource use efficiency (eg. water use efficiency, nutrient use efficiency).

These information can easily be collected by books and articles already published, by seed companies and nursery companies and by public institutions. Moreover, information can be obtained by ongoing research activities carried out by WG members.

The WG will develop strategies and collaborations with other working groups (WP1 and WG2) to gain new insights about the physiological, molecular and genetic mechanisms involved in biotic and abiotic stress resistance.

 

WG4 – Rootstock-mediated improvement of fruit quality


Leader: Cherubino Leonardi, University of Catania, Italy

C
o-Leader: Carmina Gisbert, COMAV, Valencia, Spain

Presentation of WG leader during Final Conference in Pula

This WG will compile the information on rootstock effects on commercial quality of fruits, and will define strategies for a better understanding and exploitation of the processes involved.

Specifically, this WG will collect:

  • information on the most important commercial and nutritional quality traits of the selected vegetable crops with particular emphasis to health-promoting compounds;
  • information on research activities aimed to study the rootstock influence on qualitative traits of product.

This information can easily be collected by books and articles already published. Moreover, information can be obtained by ongoing research activities carried out by WG members.

The WG will develop strategies and collaborations with other working groups (WP1 and WG2) to gain new insights about the physiological, molecular and genetic mechanisms contributing to the determinants of product quality derived from rootstock.
