Development and Applications of In Vitro Techniques / Development of rootstocks for vegetable grafting
Development and Applications of In Vitro Techniques research subgroup
In vitro culture involves several techniques that are very useful for plant breeding. These techniques include, among others: meristem culture, micropropagation, embryo rescue, genetic transformation and somatic hybridization. Our group develops and improves in vitro culture protocols and applies in vitro techniques for crop breeding, mainly in species from the Solanaceae and Cucurbitaceae families (tomato, pepper, eggplant, zucchini) as well as others such as grape. Regeneration from explants and genetic transformation can be carried out with a variety of objectives: abiotic stress tolerance, quality improvement, etc.
Development of Rootstocks for Vegetable Grafting research subgroup
Grafting consists in culturing a plant using the roots of another, and is a technique used mainly for the culture of plants that are sensitive to the pathogens that damage roots onto genotypes that are resistant. In our group, we evaluated germplasm in order to select materials resistant to Meloidogyne incognita and/or Phytopthora capsici and develop rootstocks. Compatibility and agronomic performance studies of grafted plants are included in the characterization of developed rootstocks. These studies were carried out mainly in pepper and eggplant.
