This guide provides detailed, step-by-step instructions on how to carry out the controlled mating of western redcedar (Thuja plicata Donn ex D. Don). The traditional tree breeding techniques presented are those used at the Cowichan Lake Research Station on south-central Vancouver Island, British Columbia, where western redcedar has been actively bred for more than three decades. This unique, tool-rich guide was created to help with training and information retention and transfer. It begins with a brief description of tree breeding objectives, a comparison of greenhouse versus outdoor breeding, and timelines for breeding activities, which serve to help frame and plan the many tasks. Nine breeding activities are introduced in chronological order: strobili induction, strobili production survey, phenology survey, female isolation, pollen management, pollination, cone protection, cone collection, and seed processing and storage. Important aspects of timing, as well as tools, techniques, methods or decision keys, relevant background or biological information, and supply lists are presented for each activity. The need for careful observation and precise timing as they relate to phenology is emphasized. The last chapters provide information on breeding crop production and maintenance, such as growing media formulations, container sizes, pruning and topping, and temperature requirements for indoor-grown stock.
