Notice of University Oral Examination - Clara Schortemeyer MScF Candidate-FR
Event Details:
Clara Schortemeyer, a candidate for MScF will be presenting on, "Maximizing white spruce (Picea Glauca) productivity in a drying climate through tree improvement."
ABSTRACT:
In this thesis, I quantified the genetic variation and drought response of three 20-year-old white spruce (Picea glauca) varietal test sites in New Brunswick, Canada. Our objectives were to: 1) test if volume breeding values could be used to predict drought vulnerability through tree-ring analysis of a recent multiyear drought; and 2) to quantify the within and between family variation for volume growth to determine the optimal ratio of varieties to families that need to be field tested to maximize genetic gains for growth traits. Varieties with higher genetic volume growth rates exhibited higher drought resistance, indicating that breeding for volume growth also improves drought resistance. Also, there was more within family variation than between family variation, suggesting that more varieties per family and less families should be bred and tested to maximizing genetic volume gains.
