What is plant breeding?
Mating systems and reproductive barriers: impact on population structure and plant breeding. (0,5 CFU)
Elements of evolutionary and population genetics
- Describing a population: genotypic frequencies, allelic frequencies, Hardy-Weinberg equilibrium, linkage disequilibrium
- Effects of evolutionary factors: mutation, migration, genetic drift, inbreeding, and selection. Interplay among evolutionary forces (1CFU)
Plant genetic resources in crop improvement
- Centres of origin and diversification. Domestication process and its relevance for breeding.
- Landraces, breeding and genetic erosion
- Sampling strategies and collection of genetic resources
- Conservation of plant genetic resources (0,5 CFU)
- Genetic basis of a quantitative trait
- Statistics: mean, variance, covariance, correlation and regression.
- Phenotypic value, genotypic value, environmental effect. Average effect of an allele; breeding values. Allelic interactions. Genotype x Enviromnent (GxE) interaction. Decomposition of phenotypic variance. Broad sense and narrow sense heritabilities. Covariance (resemblance) between relatives.
- Predicting response to selection on a quantitative trait
- Methods to induces genetic variability in crop
- Selection methods based on mode of reproduction: prevalently autogamous (bulk, pedigree, single seed descent (SSD), backcross) prevalently allogamous (recurrent selection, synthetic varieties, inbreeding depression, heterosis, general and specific combining ability, hybrid varieties) and clonal.
- Evaluation of selected materials in multi-environmental trials.
- Seed production
Analysis of genetic variability and biotechnologies applied to plant breeding
- Plant genomics: methods, resources, and applications (definition and examples of comparative, structural functional genomics)
- Analysis of gene expression by RNA sequencing
- Elements of population genomics
- Quantitative trait loci (QTLs) analysis. Association mapping.
- Marker assisted selection (MAS). “Breeding by design”, genomic selection and genome editing.
Successful examples of plant breeding for biotic and abiotic stresses.
