Pine, Loblolly Control Pollinated (CP) 1-0 (Pinus taeda)
Control mass-pollinated seedlings are a labor -intensive practice involving isolating female flowers prior to maturation to ensure the paternal DNA of the offspring. Essentially, after the controlled pollination has taken place, we will have seed with known parents. The testing on these seedlings has proven to be more accurate in rating growth potential. Even though the pollination is controlled, we still have considerable diversity within this seed lot. Our tree improvement personnel were able to cross several families this year, and we combined these into one seed lot. The outcome will be a 90 percent gain above unimproved seedlings.
