Courses Presented

PLTB2613 – Theoretical principles of Plant Breeding

PLTB 2623 – Applied Principles of Plant Breeding

PLTB2613/PLTB 2623 is designed to introduce the student to various theoretical principles related to plant breeding. Furthermore, this module aims to equip the future plant breeder with relevant skills to promote crop development and improvement that will impact food security positively. Students will also learn and develop an entrepreneurial mindset, critical thinking and problem-solving skills.

PLTB4806/PLTB6806

This module is a literature review and is compulsory for final year (4th year) BSc Agric and Honours students majoring in Plant Breeding. Students complete a literature study on a given topic under the guidance of a supervisor. The supervisor assesses and grades the literature review.

 PLTB4808/PLTB6808

This undergraduate module is a research project and is compulsory for final year (4th year) BSc Agric and Honours students majoring in Plant Breeding. Students complete a research project within his / her field of interest under the guidance of a supervisor.

The supervisor teaches and trains students different techniques and methodologies applicable and related to what is expected from industry. Techniques and methodologies include experimental design/performance, data collection and analysis and interpretation of results.

 PLTB8900 

Dissertation in Plant Breeding. This module focuses on a research project in a specialized field of Plant Breeding as discussed by supervisor(s), Academic Departmental head and student.
