Genetically Engineered Pear
Globally, pear are an important fruit crop with world pear production projected to hit a record high of 25.3 million metric tons in 2017. Two of the major problems encountered in the pear industry are lengthy periods required to produce improved pear varieties and tree size control. We are developing pear that have been transformed with early flowering or dwarfing genes to accelerate the pear breeding process and provide commercial growers with smaller, more manageable trees.
