3 2011 July 1, 2010 June 30, 2011 Annual Report Bureau ofcitrus BudwoodRegistration Michael Kesinger, Chief Protecting Florida s citrus industry from harmful pathogens of citrus must start in the nursery with clean stock, originating from the Citrus Budwood Protection Program. Long recognized as the best defensive strategy, using registered stock is the only option for growing trees to withstand the onslaught of debilitating diseases. The past few years has seen the entrance of new diseases: primarily citrus greening, which has caused great anguish to growers and nurserymen alike. Citrus greening has dramatically changed the way we are growing nursery stock and managing our groves. The consequence of dealing with this one disease was the move of all of our foundation stock 150 miles north, as the crow flies, to protected greenhouse structures located at Chiefland. Nurserymen made like sacrifices in building new expensive greenhouse structures to cover and protect their budwood sources and nursery stock. The result of pathogen infection is not always dramatic, with trees dying in a matter of weeks or months. Although that that can occur, rather, a gradual shifting of profitability to lower yields occurs over the course of years. Regardless of how fast a tree declines, the costs include the removal of unproductive or dying trees, purchasing and care of replacement trees, and the loss of production from the original tree. Foundation Budeyes Cut 372,370 Increase from previous year 54 % Without a clean stock program the process would start over and over again, often with stock infected by the same pathogen that took out the first tree. Over the course of 58 years of having the Citrus Budwood Registration Program, growers have saved countless dollars in avoiding costly recurring diseases such as psorosis, exocortis, cachexia, along with other citrus pathogens that were eliminated from propagating 1 Annual Report 2011 (FY ) Bureau of Citrus Budwood Registration

4 sources. The bureau ran a combined total of 36,065 laboratory and greenhouse tests for citrus pathogens this fiscal year. The Chiefland Citrus Budwood Foundation is still in its infancy, this being the fourth year of budwood production from the facility. Remarkably, four years from planting the first tree, the foundation has almost reached capacity. Measures have already been taken to be able to incorporate more trees, as some planting distances have been reduced to one and a half feet for new introductions. Once the initial budwood multiplication and release is done, some thinning of trees can occur - making room for new selections. Although planting at close distances is not sustainable for the long term, it is a necessity to be able to accept all the new material coming out of Florida s breeding programs and from the Citrus Germplasm Introduction Program. This year, Florida breeders entered 43 new selections into the bureau s parent tree indexing program in Winter Haven for testing and shoot-tip grafting. While a total of 72 new introductions were received in Winter Haven, in , fifty-one were released, and 21 were sent to Chiefland for incorporation in the foundation. One hundred-five new trees, representing 37 varieties, were planted at the Chiefland facility this fiscal year. This is an increase of 65 trees from last year. There are currently 1,160 spaces planted at Chiefland. The planted trees represent 370 different clonal selections. Some older clones were removed from the planting, and new clones added, resulting in a net increase of 32 clones. The Chiefland foundation planting is 33.8% sweet orange (392 trees), representing 86 different sweet orange varieties. Mandarins make up 33.5% of the planting (389 trees), representing 106 varieties. Grapefruit is represented with 103 trees of 27 varieties, and consists of 8.9% of the planting. Sixty-three trees of Pummelo represent 30 different clones and 5.4% of the planting. Lemons and Limes are represented by 51 trees of 20 varieties, consisting of 4.4% of the planting. Budwood cutting from Chiefland continues to increase, 385,330 bud eyes were cut and distributed to customers this year. Chiefland foundation budwood represents 12% of the industry s total source material used by citrus nurseries. This represents a 59% increase in budwood cut and distributed from Chiefland. The customer base includes 26 commercial citrus nurseries and 5 research agencies. Budwood was cut on 96 days with 176 separate budwood cuttings. Revenue from budwood sales at Chiefland amounted to $96,053. A total of 801,190 bud eyes were cut and distributed in its first four years of existence. This compares to 238,010 bud eyes cut from the Immokalee foundation greenhouses during its first four years. A second foundation greenhouse facility will be constructed on the Department of Forestry site at La Crosse, Florida during this upcoming fiscal year. This second budwood foundation will not only serve as another budwood repository in Florida, but will also house offices, laboratory and greenhouse space for the Citrus Germplasm Introduction Program (currently working out of Gainesville). It is also proposed to move the Bureau of Citrus Budwood Registration from Winter Haven to this new location. The new space should triple the division s capacity to introduce new varieties into Florida. The new site has already been cleared and fenced in, building plans have been drawn up, and sealed bids for construction should be received shortly. The Citrus Budwood Technical Advisory Committee met on April 26, 2011, at DPI in Winter Haven. The committee reviewed the Citrus Budwood Registration Program and the Citrus Germplasm Introduction Program, and selected eight new citrus varieties to introduce into Florida. A recently re-discovered film on the budwood program was shown at the meeting. The film titled Our Citrus Heritage was 50 years old, having been produced in It was interesting to see the technology of biological indexing still being utilized toady, while modern molecular laboratory tests weren t even dreamt of then. The majority of citrus nurseries (55%) are located in Polk and Highlands counties, which makes the Winter Haven budwood headquarters a well-situated location for sample collection and inspection of nursery budwood source trees. Polk and Highlands counties also lead the state in citrus fruit production. 2 Annual Report 2011 (FY ) Bureau of Citrus Budwood Registration

5 The bureau resumed seed-source testing, this year, after taking a two year hiatus from this undertaking. Seed-source trees were tested for citrus leaf blotch and citrus tatterleaf virus, which are both transmissible by seed. Every program foundation and scion source tree is tested annually for citrus tristeza virus and citrus greening. Citrus canker was discovered in the Florida citrus arboretum last year, and has continued to be troublesome. The more sensitive grapefruit cultivars were removed as a proactive measure to lessen future inoculum levels; but, with such a diverse selection of citrus types planted in the arboretum, it is difficult to eliminate all sensitive varieties. Citrus greening is perhaps an even greater threat to the arboretum s existence, as 17 new HLB positives were detected in the four-acre planting this year. This makes a cumulative total of 36 trees testing positive for citrus greening in the arboretum since the first find in August, Annually, the arboretum supplies fruit samples for the FFA fruit judging contest. Four hundred-thirty visitors signed the arboretum guest log this year, representing 12 states and 6 foreign countries. Since 2007, 26 new sites were inspected for potential citrus nursery sites. Of these sites, 14 were approved as meeting the requirements. However, only 2 of these sites are currently in actual production. Florida citrus nursery propagation figures remain similar to the production figures reported last year. Florida nurseries cut enough budwood to propagate 3,135,326 trees in This is a 4.5 percent increase from last year. The actual number of trees that make it to commercial groves is considerably less, as the propagation figures also represent trees for the homeowner market. An estimated 10 to 15 percent of the commercial citrus nursery stock is produced for the dooryard market. During the past five years, nurseries average budding 96.5 percent of the budwood cut. Some attrition also occurs in the nursery. The budwood office processed 784 bud cutting reports, which amounts to an increase of 8 reports from the previous year. The average nursery made 75 thousand propagations this fiscal year. One hundred fifty-six different clones, representing 137 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. Sweet orange propagations accounted for 2.5 million trees, or 81% of the nursery stock produced. Grapefruit and mandarin propagations decreased slightly in both number and percentage of propagations. Mandarins accounted for 244,449 propagations, or 7.8% of the total production, compared to 8.3% last year. Grapefruit accounted for 229,182 propagations, or 7.3% of the total production, compared to 7.4% last year. Lemons and Limes accounted for 1.7 of the nursery stock, and Pummelos 1.3%. Valencia and Hamlin were the top two varieties propagated, making up 36 and 33 percent of nursery propagations, respectively. Midsweet was the third most popular variety at 5.8 percent of nursery propagations, followed by Navels at 3.9%, Ray Ruby grapefruit at 2.8%, and Ruby Red grapefruit at 2.6%. Sunburst was the most popular mandarin type propagated, followed closely by Murcott then Mineola. Swingle was the most popular rootstock used for budding. This is the 23nd year that Swingle has been the top-utilized rootstock. Nursery trees on Swingle account for 40 % of all propagations, compared to 45% last year. Kuharske citrange and Carrizo citrange were the 2nd and 3rd most utilized rootstocks, accounting for 16% and 12% of propagations, respectively. Volkamer lemon along with Sour Orange, were the next most popular rootstocks, at 7.4 and 5.7 % respectively, followed by X-639 at 3.6%, Kinkoji at 3.6% and US-812 at 3.4%. 3 Annual Report 2011 (FY ) Bureau of Citrus Budwood Registration

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. 14 Annual Report 2011 (FY ) Bureau of Citrus Budwood Registration

Some years Bud Cutting Reports from the previous fiscal year were received after the cutoff date and entered into the next year s database. This is why the figure is slightly higher than the actual amount cut.

23 Lab Report Dr. Peggy Sieburth, Biological Scientist IV This year key accomplishments included training new personnel, testing the usual large volume of samples, attending the International Organization of Citrus Virologists meeting in Brazil, participating in the Citrus Clean Plant Network, and dramatically increasing the productivity of the Shoot-Tip Grafting (STGing) program. Dramatic increases in STG production were necessary this year as we had an all-time high of seventy-two new entries into the Parent Tree Indexing Program. This is more than double the number entered the previous year. Fifty-one parents and/or STGed selections were released this year, a slight increase over the 48 selections released last year. Even with this herculean effort, the backlog of total selections in the process of clean-up increased as more parent candidates were entered than were released. Once again we had our greatest production of shoot-tip grafts with the number set up increasing to 3,635 shoot-tip grafts. You can hardly imagine our feelings of accomplishment as this doubled our production compared to that of the fiscal year. 139 STGs were grafted into rootstocks in the greenhouse. At the end of the fiscal year 60 cultivars were in the process of being shoot-tip grafted. Sixty-four cultivars have been successfully STGed and are undergoing various stages of testing. Next year we hope to keep up this hectic pace as we try to increase the number of selections released and reduce the number in the system at any one time. Reducing the amount of time it takes to test a parent tree introduction has been accomplished with improvements to the biological indexing portion of the Parent Tree Program. A procedural change was made to the viroid biological indexing which then necessitated changing our pots and pot trays to support the new type of plant growth. The length of time for the viroid biological index was reduced from nine to six months, but viroid detection was improved as well. More drastic measures were needed for improving the psorosis biological index. Structural changes to the duct systems in the cool temperature house have allowed us to read plants for 10 months out of the year instead of only four months previously. This has allowed us to complete a psorosis biological test in six months to one year compared to the two years it used to take us. Accurate and efficient qpcr testing is an additional essential component of the testing. Other ways we were able to add needed improvements were with grant money from the Citrus Clean Plant network to purchase equipment for shoot-tip grafting, testing and also make needed greenhouse repairs. Being able to continue to attend the International Organization of Citrus Virologists meeting and strengthen existing ties with other germplasm programs has also been essential to germinate ideas that have been implemented to make program improvements. The average length of time to shoot-tip a selection and how that has changed over the years was analyzed. In the fiscal year at the beginning of the chart, one person was involved in shoot-tip grafting for only 15% of their time. For selections entered during that time period, it took an average of six to nine years to complete them. (The number indicated for each fiscal year represents the average length of time that all selections entered in that year took to be completed. For selections entered the fiscal year, we had been able to bring down the time to an average of 5 years. The stumbling block at this time was the requirement of an in-house fruit check. By transferring that responsibility to the owner and/or the Chiefland Foundation, we have been able to concentrate on the other aspects and reduce the time below what had been the target of five years for parent tree indexing and shoot-tip grafting. By the fiscal year we had a person with a near full time commitment to the STGing program. Also a trip to Spain to train in their laboratories helped us make some essential changes to the program. Now we have four people spending from 10 to 100% of their time directly on the STGing team, but it really involves 21 Annual Report 2011 (FY ) Bureau of Citrus Budwood Registration

24 Average # of Years to Complete STGing everyone on the whole bureau at some level from billing to planting the STGed trees, entering information in the database, washing dishes, caring for plants in the greenhouse, doing greenhouse repairs, buying supplies, etc. The most recent fiscal years may show an overly optimistic length of time for the average time for parent tree indexing and shoot-tip grafting as we only have data for the shoot-tip grafted selections that have finished early. The early years may have a longer length of time as we finally have success with varieties that we have been trying to STG for 10 years. But we have been releasing selections in under two years this fiscal year and it is a very encouraging trend that we hope will persist with a continuing focus on efficiency in this area. Hiring quality employees and intensive training in the complexities of the different jobs continues to be a focus in the testing area. Our Laboratory Technician IV has now been with us one year and we have a new Biological Scientist III. Cross-training of personnel has allowed us to keep up the furious pace with very little schedule change through the birth of two babies, sick personnel and vacation leave. The more we have increased the work, the more we have been able to find ways to become more efficient. 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.
