Black Spruce Pollen Handling

The Minnesota Department of Natural Resources began an applied black spruce breeding program in 1986. Over two seasons, pollen has been collected from 54 clones. The range of pollen germination rates is 13-81 %, averaging 47 %. In 1987, 29 controlled crosses were made according to a 5-parent disconnected diallel mating design. Collection, testing, and storage procedures are described. Plans for advanced generation breeding are discussed.
