S08. Genetic Resources in Horticulture: screening, propagation, use and conservation

The great diversity of genotypes represents a major challenge for the scientific community to find effective methods of identification and selection of individuals possessing characteristics adapted to the constantly changing climate conditions and also having nutritional and curative properties to ensure human health.

There are horticultural crops that, although they can have an essential contribution to human nutrition and health, as well as to climate change adaptation, have not been exploited. On the other hand, some genetic resources are being eroded by agricultural practices, by the destruction of habitats or due to climate change. As a result, there is a pressing need for novel approaches and technologies applied to the conservation and sustainable use of horticultural diversity.

Plant genetic resources from wild areas or from germplasm collections, represent an extraordinary biological material for study and exploitation. Thus, starting from a certain plant material are necessary: a) criteria and methods for effective identification and selection of promising accessions / individuals for their valuable and useful traits; b) agromorphological, biochemical and molecular methods/protocols to evaluate the expression of these properties under different conditions; c) new and modern approaches for maintaining, enriching and using the horticultural genetic resources from wild areas, or conserved / storaged in germplasm collections.

The preservation and sustainable use of horticultural genetic resources, as well as of autochthonous/traditional varieties, can be achieved through collaboration between groups of specialists and authorized units (farmers, private producers, researchers, research units holding germplasm collections, institutions protecting the natural heritages). Working together and in partnership, we will contribute to the in-depth knowledge of the genetic diversity of horticultural plants and to the rational and efficient use of this variability.

This symposium has the following main topics for debate:

  • Genetic pools of horticultural crops and their present availability for research purposes and   sustainable use
  • Phenotypic traits, biochemical and molecular techniques applied for identification and selection (screening) of valuable genotypes in horticultural crops
  • Modern methods for propagation and maintenance the horticultural genetic resources - in situ and ex-situ collections;
  • Using the horticultural genetic resources (wild and cultivated species, autochthonous/local cultivars for developing high-yielding and biotic and abiotic stress tolerance); Conservation and sustainable use of horticultural genetic resources – approaches, strategies, and policies.
  • Horticultural genetic resources used in complex studies of evolutionary biology, essential for understanding their ancestral origin and possible use as genitors in breeding programs.
  • Miscellaneous
