MAIN DIRECTIONS OF THE SCIENTIFIC RESEARCH ACTIVITIES 1) Development, adaptation and application of genetic engineering methods (tissue

cultures, cell and molecular genetics) aiming to increase the effectiveness of the genetic and breeding programmes for increasing the efficiency of creation of valuable genetic diversity in economically important species, bearing carrying agronomically valuable traits like: - Resistance to diseases (virus, fungal and bacterial), herbicides (in order to

eliminate weeds and parasite plants), heavy metals and pesticides in soil, drought � freezing (low and high temperatures);

- Improving plant qualities, used as food for humans (β-carrotin, licopin) and animals (consistance of aminoacids, proteins, lignin, lactoferrin, etc.)

- Improvement of early raping and productivity; - Increasing the quality and quantity of biologically (secondary) active

compounds in medical and herbal plants.

2) Development, adaptation and application of DNA marker methods for accelerating and improving the effectiveness of plant breeding process based on an early evaluation of the breeding material, derived from remote hybridization and somaclonal variations in economically important cultures: barley, wheat, sunflower, tomatoes, tobacco etc. Development of highly effective methods for genotyping and evaluating the available genetic resources resources, keeping the purity and stability of the existing varieties and hybrids and the protection of the intellectual property rights.

3) Development, adaptation and application the methods of in vitro clonal micropropagation and virus diagnosis of valuable vegetatively propagated species and field crops and the development of prebasic and basic certified material for the respective nurceries and breeding programs. The final goal is to develop genetically authentic and phytosanitary healthy plant material.

4) Development, adaptation and application of gene cloning methods for establishing a unique gene bank, containing genes determining economically important

4

characters, needed for the improvement of plant breeding programmes through gene transfer techniques.

5) Development, adaptation and application of genomics methods for unique national germlasm with high economical value by studying the expression and function of various metabolites in relation of the variations of the genotypes and the environment.

6) Establishment and application of biosafety regulations. Organization of the control in the use of genetically improved plants. Evaluation and management of the risk from developing and releasing GMO into the environment. Increasing the public knowledge and creating of national information system – biosafety database.
