National Tree Genomics Program

Project Summary

The National Horticultural Tree Genomics Program will advance our ability to rapidly develop and implement horticultural tree cultivars that accentuate key productivity and profitability traits. Currently, many tree crops take years to flower and have architectures that require low planting densities. Long generation times delay breeding programs and lengthen the time needed for growers to see return on their investment.  

The Program is focusing on improving tree architecture and time to first flowering in five target species – almond, avocado, citrus, mango, and macadamia. These large tree crops have long juvenile phases before they begin to flower.  Therefore, we are focused on developing smaller trees that flower sooner to reduce the time growers and breeders must wait for a return on investment from planting new varieties. Smaller trees can also be planted at higher densities and in many cases outyield larger trees on a per hectare scale.
