This course examines principles of plant breeding in self- and cross-pollinated crops. Additional topics include crop domestication, mating systems, heritability, gain from selection, disease resistance, polyploidy, marker assisted selection and government regulations. Offered in conjunction with MBG*4160. Extra work is required of graduate students.

Topics to be covered in labs include:
-

-
Pollination of crop plants
-
Estimates of heritability
-
Diversity and breeding in flax
-
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.
Communicating with Instructors
- During the course, your instructor will interact with you on various course matters on the course website using the following ways of communication:

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:

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.
