We have identified HLB resistant sources and generated hundreds of hybrids in the past five years. Since development of HLB resistant scions or rootstocks is a long term process, we propose to explore possible ways of using resistant hybrids to impart this trait to commercial citrus. We will study transfer of resistance through inarches, topworking (of one branch only), and combination of inarch and topworking. Ability to impart resistance to existing commercial stock/scion combinations would greatly benefit the industry.
