Labs & Seminars:

Topics to be covered in labs include:

  • Rapid cycling brassicas
  • Statistics 
  • Pollination of crop plants
  • Estimates of hertability
  • 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.
