Resistance and tolerance to Huanglongbing in citrus[abstract].2016 California Citrus Showcase. March 3, 2016, Visalia, California Interpretive Summary: Technical Abstract: The Stover-led research team focuses on developing improved citrus scion varieties, through both conventional breeding and transgenics, with special attention to confronting the threat of citrus huanglongbing (HLB). Collaborations are underway with more than 20 research groups around the world to harness the most promising science in developing HLB tolerant and resistant citrus scion material. Funding has been obtained from diverse sources to expedite this work, with many projects funded by citrus grower- managed organizations such as the Florida Citrus Research and Development Foundation, the California Citrus Research Board, and the New Varieties Development and Management Corporation. Projects are focused on the short-, intermediate- and long- term. Several existing scion cultivars and a number of advanced selections have been documented to show apparent tolerance to HLB, and are being tested more broadly in Florida and being imported into California. Resistance has been found in more distant citrus relatives and so far tolerance is conferred to some hybrids with conventional citrus, with a number of projects underway to better understand use of this resistance in citrus breeding. Extensive hybridizations and evaluations are underway to pyramid apparent resistance and tolerance in hybrids with desirable market characteristics. A number of transgenic approaches have been implemented and material is at all stages of development and evaluation. |
