Course abstract

In the course work, students summarize the knowledge acquired during the study process and learn how to apply it in practice. Students strengthen their knowledge of heredity and variability of plants, and the process of breeding new cultivars.

Learning outcomes and their assessment

1. Summarized knowledge of the basics of horticultural plant breeding - genetics, breeding process, peculiarities of self-pollination and cross-pollination, methods of breeding and selection - literature review part of the course work.
2. Skills to develop a breeding plan for horticultural plants, to evaluate the use of different breeding methods in obtaining high quality cultivars - experimental part of the course work.

3. Competences to study and review information independently, to prepare presentations, as well as to justify own decisions and to justify opinions - defense of course work.

Course Content(Calendar)

Sample for the Course work plan:
Introduction (importance of the crop, production, problems, breeding possibilities, aim and tasks of the work).
1. Literature review
• Botanical systematics and origin of the crop selected for breeding.
• Development of a basic breeding directions and cultivar models - showing, for example, plant size, flower or fruit color, yield and resistance to environmental factors etc.
• Research of cultivation and breeding history of a given plant, contemporary achievements in breeding.
• Characteristics of the breeding genepool (species, varieties, rootstocks).
• Description of possible breeding methods for the selected crop (hybridization, mutagenesis, polyploidy, etc.).
2. Experimental part
• Selection of parent pairs and detailed hybridization methodology; desirable images of flower arrangement, crossing and pollination.
• Hybridization plan (in the form of a table), give pair (simple), complex hybridization and becross. Show in the table: Valuable and undesirable properties of the Mother plant, characteristics desirable to transmit; The valuable and undesirable qualities of the Father's plant, characteristics desirable to transmit; Aim of the hybridization - Expected valuable characteristics. In the table show the selected type of hybridization and record the distribution of genetic material by parent,%
• Evaluation of breeding material.
• Breeding of new hybrids and cultivars, cultivar tests, DUS and VCU tests, cultivar registration.
Conclusions. You should write specifically about your experiment

Literature: at least 10 sources of literature, mainly scientific reviews, monographs and articles from scientific conferences.
For the defense of the course work, presentation should be prepared for 7-8 minutes.
