Labs & Seminars:

Topics to be covered in labs include:

  • Rapid cycling brassicas
  • Heritability
  • Statistics in plant breeding
  • Pollination of crop plants
  • Soybean breeding
  • Asparagus breeding

Rapid Cycling Brassicas - A population of B. rapa which matures in 35 to 40 days was developed by Dr. P. H. Williams at the University of Wisconsin. With this genetic material you will perform a selection experiment and estimate gains from selection and realized heritabilities.

Term Paper and Oral Presentation - Students will be assigned a plant breeding topic (e.g. heterosis, interspecific hybridization, comparison of breeding methods, etc) and will write a 10 page review paper based on primary literature. A 20 minute seminar will be presented during the last two weeks of class. 

Heritability - Students will be given data sets and instructed in the calculation of heritability.

Statistics in Plant Breeding - Students will calculate and interpret some basic statistical parameters commonly used in plant breeding.

Pollination of Crop Plants - Students will perform emasculation and pollination of some common crop plants in order to practice some common breeding techniques.

Discussion of Journal Articles - Students will be asked to analyze journal articles. Questions will be assigned before lab and answers will be collected at the start of lab. Answers do not need to be correct but student must show preparation before coming to lab. Each of the two exercises is worth 2.5 pt to the final grade.

Grading Policies

All assignments are due at the beginning of class on the prescribed dates. Late penalty is 10% per day from the due date and time. Late assignments will not be accepted after 3 days.

Course Policy on Group Work:

All submitted work is to be an individual effort with no collaboration or sharing of answers; this includes use of materials from previous years. Laboratory data may be collected as a group, however, analysis and written lab reports are individual efforts.

Course Policy regarding use of electronic devices and recording of lectures

Texting and use of electronic devices, except for laptops, are prohibited in lecture and lab.

Electronic recording of classes is expressly forbidden without consent of the instructor.  When recordings are permitted they are solely for the use of the authorized student and may not be reproduced, or transmitted to others, without the express written consent of the instructor.

Academic Consideration

When you find yourself unable to meet an in-course requirement because of illness or compassionate reasons, please advise the course instructor in writing, with your name, id#, and e-mail contact. See the academic calendar for information on regulations and procedures for Academic Consideration:

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.

For more information, contact CSD at 519-824-4120 ext. 56208 or email sas@uoguelph.ca or visit the Student Accessibility Services website: http://www.uoguelph.ca/csd/.

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.
