The current breeding strategy incorporates optimum contribution selection (to manage gain/diversity) and genomic prediction (to speed the breeding cycle). We use topgrafting to induce flowering. Our progeny testing strategy supports both scoring families for deployment (PRS) and re-training genomic prediction models. MateSel is used to develop annual crossing plans considering the current state of the population (which trees have flowers/pollen and their relatedness with the rest of the population), with mating groups to maintain adaptability (flexible breeding zones).

The success of this breeding program is made possible by in-kind contributions from TIP Full Members (especially progeny testing in the field, sowing seedlings in the nursery) and the dedication of TIP staff and students. Our primary orchard facility, the Arrowhead Breeding Center, is graciously hosted by the Georgia Forestry Commission and funded by TIP Contributing Members.

I started managing the breeding program in 2015 during the 4th-Cycle mating and testing. In 2019-2025, I helped introduce incremental improvements into the 5th-Cycle breeding strategy. In 2023, I stepped into a leadership role to keep the program’s strategy world class.
