PLNT*6160 Advanced Plant Breeding II

course node page

The following description is for the course offering in Winter 2019 and is subject to change. It is provided for information only. The course outline distributed to the class at the beginning of the semester describes the course content and delivery, and defines the methods and criteria to be used in establishing the final grades for the course.
 

The course is designed to familiarize plant breeding graduate students with the theory and application of quantitative genetics in plant breeding, help them understand the fundamentals of population genetics, and explore how quantitative genetics principles and modern tools can help a plant breeder design and implement a breeding program to improve quantitative traits and to study complex traits. The course is intended to provide opportunities for continued learning, critical questioning and discussion of research findings and communication skills. Emphasis is placed on gaining hands-on experience data management and analysis that resembles real-life plant breeding and quantitative genetic problems and situations.

Grading Policies:

Homework assignments will be assigned at the time of lecture on each topic and will be due in class three weeks afterwards.

Assignments (40% of the final mark): Four homework assignments (each worth 10% of the final mark) will be handed out in class. For each assignment, students will be supplied with a data-set and in some cases sample analysis SAS codes/software. Students are asked to write a report, in which they will follow the format of a scientific paper with Introduction, Materials and Methods, Results (including tables and Figures), Discussion, and References. Students will need to go over the basics of the analysis, discuss several relevant papers, and then and interpret the results.

Paper Discussion and Participation (20% of the final mark): Each paper discussion will have one moderator, leading the discussion, and the rest of the class will actively participate in discussions. Students will be marked for both their moderator role and discussion participant role.

Student Presentations or tutorial videos (20 % of the final Mark – Peer-graded): Each Student is to pick one of the topics of the course and prepare a 20 Min presentation to review the recent pertinent literature. Alternatively, they can work with a team of three students and make a tutorial video for a software.

Quizzes (20% of the final Mark): Students will write 5 Quizzes throughout the semester. Students will be informed one week before. 4 quizzes will be counted towards 10% of the total mark.

Discussion of Research Papers: Research articles will be discussed as part of the class. Students will be expected to thoroughly read and prepare for a discussion of all papers as their participation (emphasis on relevance and quality of contribution rather than time spent discussing it) will make up part of their overall grade for the course. Discussion of papers should take into consideration such items as objectives and purpose of the research, adequacy of the methodology used, and the scientific impact of the results.

A discussion moderator will be assigned for each paper. Their role will be to make sure that all relevant points in the paper are discussed. Their role is not to present the paper to class but to involve all students in the discussion by asking questions and making references to concepts, data and its interpretation in the paper.

Note: Papers will be handed out in class or via e-mail, and will also be posted on the course website on CourseLink.

Academic Misconduct

The University of Guelph is committed to upholding the highest standards of academic integrity and it is the responsibility of all members of the University community, faculty, staff, and students  to be aware of what constitutes academic misconduct and to do as much as possible to prevent academic offences from occurring.

University of Guelph students have the responsibility of abiding by the University's policy on academic misconduct regardless of their location of study; faculty, staff and students have the responsibility of supporting an environment that discourages misconduct. Students need to remain aware that instructors have access to and the right to use electronic and other means of detection. Please note: Whether or not a student intended to commit academic misconduct is not relevant for a finding of guilt. Hurried or careless submission of assignments does not excuse students from responsibility for verifying the academic integrity of their work before submitting it. Students who are in any doubt as to whether an action on their part could be construed as an academic offence should consult with a faculty member or faculty advisor.

The Academic Misconduct Policy is detailed in the University Calenders:

Accessibility

The University of Guelph is committed to creating a barrier-free environment. Providing services for students is a shared responsibility among students, faculty and administrators. This relationship is based on respect of individual rights, the dignity of the individual and the University community's shared commitment to an open and supportive learning environment. Students requiring service or accommodation, whether due to an identified, ongoing disability or a short-term disability should contact the Student Accessibility Services (SAS), formerly Centre for Students with Disabilities (CSD), as soon as possible.

Course Evaluation Information

Your ratings and comments are important.  Course evaluation data are used to assess and enhance the quality of teaching and student learning at the University of Guelph.  Student course ratings and comments are used as an important component in the Faculty Tenure & Promotion process, and as valuable feedback to help instructors improve their teaching effectiveness and to improve the delivery of the course.

Your responses will not affect your grade.  Course evaluation data are distributed to individual instructors after final grades have been submitted to the Registrar, following the completion of each academic semester.

Please be honest, respectful, constructive and thorough.  Instructors and review committees place great value on student course ratings and read all comments provided in course evaluations. It is helpful to provide comments on the strengths of the course, in addition to the areas for improvement.  Please refrain from personal comments unless they relate to teaching and learning.
