Course Contents
The following items will be covered within the course program: Basic principles vegetable breeding; past and current objectives of vegetable breeding; vegetable genetic resources; evaluation and characterization of vegetable genetic resources; designing and preparing and vegetable breeding programs; field layout in vegetable breeding; evaluation and selection of traits of interest; introduction and discussion of appropriate breeding techniques.
Weekly Detailed Course Contents
1Introduction to the class and vegetable breeding.A brief description of the course will be provided.
2Traits of interest. Breeding trends in the past and future.A discussion will be made on the needs and expectations of modern agriculture from breeding.
3Designing plant architecture.Breeding is an art: a virtual practice on traits of interest
4Breeders’ own knowledge and the need for collaboration.A discussion on various disciplines’ contribution to vegetable breeding.
5The flower. Sexually propagated vegetables will be introduced.Discussion on examples of various pollination types in vegetable crops.
6Inbreeding-outbreeding. Mechanisms leading to outbreeding will be explained and examples given from vegetables and their wild relatives. A practice on controlled pollination techniques, and formation of hybrids is planned.
7Introduction to variability in vegetable crops. Vegetable genetic resources such as wild relatives, closer relatives, domestic landraces will be explained.A discussion is planned on the value of old cultivars, landraces etc. by considering them as possible gene sources for modern varieties.
8Midterm exam
9Introducing variability.Collection missions and gene banks will be taught. The importance of exotic vegetables will be outlined. A discussion will be made on a production with landraces and old cultivars by considering in-situ, ex-situ and on-farm conservation strategies.Practice on experimental field layout and statistical analysis in evaluating introductions. Evaluation of papers and discussion
10Creating variability. Mutation breeding, hybridization will be outlined as possible sources of variability.A virtual practical is planned on mutants and their economic values for agriculture.
11Assessing variability. Observed variability in vegetables will be classified by a hierarchical method. A comparison will also be made between molecular and morphological variability.Practicals on techniques in classification of diverse genetic material are planned. A practice will also be done to obtain dendrograms from molecular and morphological data.
12Screening for useful traits.Practice on field layout and statistical anayisis in screening.
13Daily trip to a vegetable breeding company.Discussion.
14Individual project presentations.Discussion of the presentations.
15Individual project presentations.Discussion of the presentations. Subsequent evaluation of the course.
16Final examA general exam will be performed covering all subjects
