3 Annual Report 2010 July 1, 2009 June 30, 2010 Bureau of Citrus Budwood Registration Michael Kesinger, Chief The Bureau of Citrus Budwood Registration regulates citrus budwood distribution in Florida s commercial citrus nurseries. Testing propagating material and maintaining protected foundation budwood clean stock is fundamental to keeping graft-transmissible diseases out of nurseries and ultimately providing growers clean stock to plant. The citrus nursery industry has made significant investments in nursery infrastructure to safeguard nursery stock from threatening pathogens. Inspection and testing by the Division of Plant Industry complement industry efforts to manage disease threats. The combination of proper structures, management, clean stock and regular monitoring are effective in growing disease-free trees. Major advancements in the technology of laboratory equipment has allowed for greater sensitivity in testing for plant pathogens. The Chiefland Budwood Foundation facility has approximately 1.5 acres of secure greenhouse growing areas which are used to provide registered nurseries with clean stock material. Nurseries must obtain their original source stock from the Chiefland Foundation. Citrus nurseries can then establish their own scion or increase source material from the foundation stock. One key to the whole process is maintaining the proper identity of each propagation every step of the way. All nurseries must report all citrus propagation to the budwood office on Bud Cutting Reports that identify the source of all propagations and their locations within the nursery. These reports can be used to trace source material back to original parent sources. Fiscal year budwood cutting in Florida nurseries amounted to 3 million bud eyes for The Chiefland Budwood Foundation cut and distributed 241,650 bud eyes for industry use this year. Since the beginning of the budwood program, over 13 million bud eyes have been distributed from foundation trees - bringing in over $892,000 in revenue. The 241,650 bud eyes cut from Chiefland this year were an 82 % increase from the amount cut last year. This amounts to 8% of the total industry demand for budwood and represents the highest demand for foundation budwood in recent memory. Budwood sales from Chiefland brought in $55,396 of revenue to the division. One hundred thirty-five different clones were cut this year, and distributed to 36 different customers, including 29 nurseries. Budwood was cut on 78 days with 185 separate bud cutting reports processed. The lowest temperature recorded outside the Chiefland greenhouse during the winter of 2010 was 15 degrees. Approximately 6,360 gallons of LP gas were burned this year to keep greenhouse temperatures above 50 degrees. The Citrus Budwood Technical Advisory Committee met once this year in the Chiefland conference room, and the Division of Plant Industry held 2 staff meetings at Chiefland this fiscal year. Currently 1,091 spaces are planted at Chiefland. This is an increase of 120 trees from last year. Extra tree spaces were obtained by planting many of the new selections closer together in the rows, as close as a foot and a half apart. The planted trees represent 338 different clonal selections. Some older clones were removed from the planting and new clones added resulting in a net increase of 17 clones. The Chiefland foundation planting is 35.7% sweet orange (389 trees), representing 83 different sweet orange varieties. Mandarins make up 28.9% of the planting (315 trees), representing 82 varieties. Grapefruit is represented with 100 trees of 26 varieties, and consists of 9.2% of the planting. Annual Report 2010 (FY ) Bureau of Citrus Budwood Registration 1

4 The Chiefland greenhouse structure and trees are inspected every day by on-site staff. Another monthly inspection is performed by plant industry nursery inspection staff. Close monitoring is important to prevent breeches in the structure that could jeopardize the clean stock. Visitors are not permitted access to the growing areas of the Chiefland facility; although a small viewing window is present to allow the curious a glance inside. Twenty-eight new varieties were planted at Chiefland this year. New varieties must be grown and fruited out before an official industry release. Researchers frequently plant new varieties in trial plantings before official release, so attributes and characteristics under Florida growing conditions can be more fully known. New varieties enter the budwood program from three different means. Varieties coming from outside Florida must enter through the Citrus Germplasm Introduction Program (CGIP) for quarantine and pathogen testing before being taken to Chiefland. Research agencies and instate breeding programs are continually developing new scions and rootstocks specifically for Florida s needs. New varieties, originating from Florida research agencies enter through the budwood program and are tested in the DPI Winter Haven laboratory and biological greenhouses, and are usually shoottip grafted to remove any pathogens. Citrus growers can also enter varieties into the parent tree program, and they have been responsible for entering many new selections from better yielding trees or unique finds in their groves. Thirty-four new selections entered the budwood program s parent candidate program this fiscal year and 48 different shoot-tip grafted selections were released. Improvements in the shoot-tip grafting laboratory include the acquisition of a two new microscopes. The first scope has higher magnification and better optics than our previous equipment for performing the shoot-tip grafting. The second scope is a teaching microscope used to train shoot-tip grafting techniques to employees and visiting scientists from other programs, and for team projects. The number of commercial citrus nursery propagations were lower this year by 763,073 or 20%. Florida nurserymen made 3,001,186 propagations in The decline in nursery production is attributed to fewer sweet oranges being propagated, as every other citrus type saw increased production in While sweet orange propagations were down by 957,104, grapefruit and mandarin propagations increased in both number and percentage of the propagations. Grapefruit accounted for 7.4% of all propagations compared to 4.7% last year. Mandarins accounted for 8.3% of propagations compared to 4.1% last year. Sweet oranges declined, from 89% of the propagations to 79.7%, this year. The average nursery made 67 thousand propagations this fiscal year. Forty-one percent of Florida s nursery trees are produced in Polk County, where the budwood office and the majority of the citrus nursery inspectors are headquartered. One hundred seventy-two different clones representing 148 different varieties were propagated this fiscal year. Although the citrus industry utilizes only a handful of varieties in commercial plantings, the dooryard (homeowner) market employs a greater assortment of citrus types. It is estimated that ten to fifteen percent of the total reported nursery propagations are destined for dooryard trees. Valencia and Hamlin were the top two varieties propagated, making up 37 and 33 percent of nursery propagations, respectively. Midsweet was the third most popular variety at 3.3 percent of nursery propagations, followed by Ray Ruby grapefruit at 3.2%, Glen Navel at 3.0% and Ruby Red grapefruit at 2.3%. Murcott was the most popular mandarin type propagated, followed closely by Mineola. Swingle was the most popular rootstock used for budding. This is the 22nd year that Swingle has been the top-utilized rootstock. Nursery trees on Swingle account for 45 % of all propagations. Kuharske citrange and Carrizo citrange were the 2nd and 3rd most utilized rootstocks, accounting for 17% and 14% of propagations, respectively. Sour Orange and Cleopatra mandarin were the next most popular rootstocks at 7.5 and 3.5 % respectively, followed by X-639 at 3.1%, Kinkoji at 2.7% and Volkamer lemon at 2.2%.

5 The bureau conducted 44,299 pathogen tests in Every program foundation and scion source tree is tested annually for citrus tristeza virus and citrus greening. Testing for other pathogens occurs on a routine basis, with a different pathogen focus each year. This year, citrus tatter leaf virus and citrus psorosis virus were tested for in program sources. A paper titled Increased Efficiency and Sensitivity for Identifying Citrus Greening and Citrus Tristeza Virus using Real-time PCR testing was published by bureau laboratory personnel in the Proceedings of the Florida State Horticultural Society in All nursery budwood sources are required to be grown in protected greenhouses that have to be approved by the Division of Plant Industry, while seed source trees can be field grown. Scion trees are responsible for providing 50% of the propagation material for citrus nurseries, with the average scion tree producing 784 bud eyes. Increase trees, which can originate from either foundation or scion trees, accounted for 42% of nursery propagation material. Qualifying increase trees, those originating from foundation trees, can be converted to scion trees by being witnessed and tested for pathogens. The bureau witnessed 1,276 scion trees this fiscal year: 1,171 budwood scion, and 1,105 seed source trees. The total number of scion tees in the program stands at 9,529, of which 5,722 are budwood scion and 3,807 seed source. Source tree registration revenue amounted to $38,985 for the fiscal year. The first find of citrus canker in the Florida Citrus Arboretum was in March of The find was on the outside row of grapefruit trees. To protect the remainder of the arboretum, three rows of grapefruit have been removed. The first find of citrus greening in the arboretum, which was one of the first finds in Polk County, was in August of Removal of trees with citrus greening in the arboretum has also been aggressive. The first year, 2 trees were identified with HLB and removed (FY 2008), followed by 2 trees in the second year (FY 2009). Eleven trees were found positive and removed from the arboretum in the fall of 2009 (FY 2010), followed by an additional 4 trees in the spring of 2010 (FY 2010). Twenty-three trees were reset in the arboretum in 2010, and 16 were reset the previous year. The Dundee foundation facility, which has not been used for budwood cutting since , has been taken over by the Division of Plant Industry s Bureau of Methods Development and Biological Control. Dundee barns and greenhouses are being renovated for a biological control rearing facility for parasites of the Asian citrus psyllid. This use of the facility should help in the industry s battle against citrus greening. This year s report contains new data and more information than ever before. Eight pages are devoted to providing clonal background information, including a brief history and description of selections propagated within the past five years. Program files were used to provide a historic data recap of budwood cutting from various foundation locations throughout the years. The foundation budwood cutting report can be found on page 7. Participant activity is highlighted on page 6, providing a historic look at new budwood program participants by year. At the Division of Plant Industry we protect the food supply and help keep it safe, affordable and abundant. - Richard Gaskalla Annual Report 2010 (FY ) Bureau of Citrus Budwood Registration 3

Since , the amount budded figure is used when numbers are divided by various rootstocks and amount cut is used when budded information is not available. Reported propagations in prior years were artificially low, as not all nurseries submitted bud usage and only platted buddings were counted. 2 Florida Commercial Citrus Acreage Biennial Data From Florida Agricultural Statistics Commercial Citrus Inventory A data project was begun in 2004 to archive old records from the Bureau of Citrus Budwood Registration in a database. This project draws data from several different office record sources that frequently differ in the way they were calculated. New validated releases were tabulated in a separate book from registered propagations and have to be combined when entered into database tables. This project resulted in corrections made to some nursery propagation figures as these different records were reconciled. This project is now complete.

21 Lab Report The main improvement this fiscal year for the annual qpcr testing was to quantitate the actual amount of nucleic acids in each sample. All samples are adjusted so the optimal amount of nucleic acids are used in each assay. Using the optimal amount for each test, improved the sensitivity of our testing. Once again, testing for Citrus greening (HLB) showed that all of the Budwood source trees in the foundation and screen houses tested negative. Citrus tristeza virus (CTV) testing detected 5 trees with severe isolates of CTV. This is the second time these trees were tested by the more sensitive qpcr, and the first time with a known quantity of nucleic acids. We do not expect to detect any more trees with severe CTV. The extract from the one annual collection was this year used to test source trees for Citrus psorosis virus and Citrus tatter leaf virus (Apple stem grooving virus). Initially foundation trees were tested one time for these viruses by biological indexing. They were not retested. These two qpcr tests detected only Citrus tatter leaf virus in Buddha s hand. It is being Shoot-tip grafted to remove this pathogen. We were able to fill our vacant Laboratory Technician IV position in January. This position is important for support in the annual collections, extraction of samples, and biological indexing. However the additional daily support in Shoot-tip grafting allows us to continue to increase the number of selections that we receive, clean up and complete. An important Agricultural Technician III position became vacant with the retirement of the incumbent after ten years of service. Hiring good people and intensive training in the complexities of the different jobs continues to be a focus in the testing areas. Over fifty percent of the laboratory effort is now going into the cleanup of new and existing varieties. This supports our mission of having all possible Florida Germplasm selections as disease free as possible and kept safe in our screen house facility at Chiefland. Thirty-four new entries were made into the Parent Tree Indexing Program and 48 parents and/or STGs were released this year. As we continued to increase STG production in , we again had our greatest production of shoot-tip grafts. The number set up increased to 2165 shoot-tip grafts, of these, 138 were grafted into rootstocks in the greenhouse. At the end of the fiscal year 42 cultivars were in the process of being shoot-tip grafted. Sixty-three cultivars have been successfully STGed and are undergoing various stages of testing.

45 Our Vision The Bureau of Citrus Budwood Registration will provide high yielding, pathogen tested, quality budlines that will positively impact the productivity and prosperity of our citrus industry. Our Mission The Bureau of Citrus Budwood Registration administers a program to assist growers and nurserymen in producing citrus nursery trees that are believed to be horticulturally true to varietal type, productive, and free from certain recognizable bud-transmissible diseases detrimental to fruit production and tree longevity. Benefits of a Budwood Program The Florida budwood program has positively impacted Florida citrus, as the use of registered budwood selections, or budlines, is responsible for impressive increases in yield and fruit quality in the industry. The budwood program introduced many nucellar lines that are still the basis of many of our main varieties. The ability to test for graft-transmitted pathogens, and exclude unclean propagating material, has not only increased production and tree longevity, but also the ability of our groves to withstand other environmental stresses. Diseases are kept out of the propagation system o Using clean nursery stock means growers receive disease-free trees coming out of the nursery Testing for citrus viroids is more critical than ever, as the industry uses predominantly citrange and citrumelo type rootstocks that are more susceptible to viroids o The budwood program is credited with having viroid-free trees for the industry to use when the rootstocks were changed from rough lemon and sour orange to Carrizo and Swingle Other countries without budwood programs had major viroid problems when changing rootstocks away from sour orange Citrus tristeza virus strains are worse today than a few years ago o Stem pitting tristeza virus strains have been found in several commercial grove locations in Florida Psorosis virus is becoming hard to find in Florida after 50 years of budwood registration o Prior to the budwood program psorosis was widespread in Florida Yields in psorosis infected trees were reduced 10 to 35 percent Resistance to freezes and other environmental factors were compromised with infected trees Protection of our industry from exotic citrus diseases requires controlling citrus propagating material o Citrus greening is the latest disease to move from the exotic disease list to become an endemic disease o Citrus variegated chlorosis and citrus sudden death are examples of pathogens whose main means of control is budwood certification Grove trees started from clean stock have the potential to be profitable even in the presence of disease, whereas nursery trees started systemically infected will never become profitable grove trees Yields are increased with registered budwood clonal selections o Nucellar Valencia clones alone increased yields by 25% over old line selections o Examples of registered clonal selections in every variety show remarkable yield gains True to type varieties and rootstocks are propagated o Inspected trees with off-types are removed from budwood supply Budwood programs are recognized worldwide as the most effective means of excluding and containing citrus graft-transmissible pathogens Annual Report 2010 (FY ) Bureau of Citrus Budwood Registration 43
