Parent Trees<br />
Parent trees are unique germplasm belonging to a nurseryman, grower, or breeder, or on property that the<br />
owner has given written permission to a nurseryman <strong>and</strong> the department for access for observation, testing,<br />
<strong>and</strong> shoot-tip grafting. Parent trees are not used as a source <strong>of</strong> budwood for nursery trees; they only supply<br />
the initial material that is shoot-tip grafted to become a registered clonal selection.<br />
The process <strong>of</strong> selection <strong>of</strong> superior budlines helped the citrus industry exp<strong>and</strong> with new plantings <strong>of</strong> uniform<br />
fruit <strong>and</strong> uniform crops <strong>of</strong> high yield <strong>and</strong> quality. A simplification <strong>of</strong> the selection process is basically the<br />
“elimination <strong>of</strong> undesirable characteristics <strong>and</strong> increasing the desirable characteristics” <strong>of</strong> a variety. Many <strong>of</strong><br />
the Valencias, grown before the budwood program helped st<strong>and</strong>ardize the variety, were a hodge-podge <strong>of</strong><br />
many different named types <strong>and</strong> seedling selections. A high percentage <strong>of</strong> these late varieties as a group had<br />
a tendency towards bud-mutations along with carrying viruses <strong>and</strong> not yielding the volume <strong>of</strong> fruit that was<br />
possible. Other commercial varieties likewise were improved through the selection <strong>of</strong> st<strong>and</strong>ardized true-totype<br />
varieties <strong>and</strong> the subsequent improvement in yields <strong>and</strong> fruit quality. Bud improvement through<br />
selection, along with pathogen removal gave the grower a double bang for their buck, exponentially<br />
increasing production <strong>and</strong> tree survivability.<br />
