Feasibility Of Supplemental Mass Pollination To Increase Genetic Gains From Seed Orchards

Dyed pollen was applied to unprotected clusters of female strobili of three clones in a mature, loblolly pine, (Pinus taeda L.), seed orchard. Single and multiple pollinations were made as strobilus receptivity progressed. Dissection of ovules on strobili collected after the pollination season was past revealed that supplemental mass pollination to increase genetic gains is feasible with proper timing and application. The best average percentage of dyed pollen in ovules of the three clones was 92% for multiple pollinations. An average of 86% dyed pollen was introduced into pollen chambers of the three clones with a single application when strobili were at maximum receptivity.
