BIOL 3763 (BT38L) CROP IMPROVEMENT (formerly Plant Breeding) (4 credits)

Prerequisites: BL27B or AC24A Syllabus: Objectives of plant breeding; Crop evolution and genetic vari- ability; genetic erosion and germplasm conservation. Creating genetic variability – mutagenesis, somaclonal variation, inter- and intraspecific hybridisation. Reproductive isolation sys- tems and their manipulation; Principles of selection-factors affecting genetic gain, selection methods, marker assisted se- lection and response to selection. Principles and methods of breeding self-pollinated cross-pollinated and vegetatively propa- gated crops. Case studies. Breeding for disease resistance. Impact of biotechnology on plant breeding. Seed production

BIOL 3765 (BT38G) PLANT PATHOLOGY (4 credits)

Prerequisites: BL28C or AG13A or AG13B Syllabus: Biotic and abiotic causes of plant disease. Pathogenesis, dis- ease development and symptomology. Etiology: dispersal and survival of plant pathogens. Epiphytotics and disease fore- casting. Defense mechanisms in plants; active and passive. Principles of plant disease control: exclusion, eradication, pro- tection, disease resistance and integrated control. Fungicide usage. Study of selected plant diseases of importance in the

BIOL 3766 (BT38J) PLANT ECOPHYSIOLOGY (not offered in 2004/2005) (4 credits)

Prerequisites: (BL11G & BT27A) or (AG13A & AP12B) Syllabus: Interactions between plants and their environment in various ecosystems – deserts, rain forest, swamps and savannas. The nature of plant injuries and resistance mechanisms to biotic and abiotic stress factors. Plant adaptations that favour sur- vival and growth in specific environments and the balance of water, mineral nutrients, energy and carbon in various plant communities. Environmental influences on plant life cycles and productivity and the relevance of this information in eco-

system management.
