JUDE GROSSER

Breeding Citrus Scions and Rootstocks for an HLB-Endemic World

My research program in citrus variety improvement addresses all major citrus production problems in Florida, and also strives to develop new cultivars that will provide growers with new marketing opportunities. Using a team-oriented approach, my program is integrated with other members of the IFAS/CREC cultivar improvement team (F. G. Gmitter, W. S Castle, and G. A. Moore) as well as entomologists, pathologists, and physiologists. I have been a consistently
productive full professor, as evidenced by a ‘Superior’ faculty evaluation every full year that I have been employed by UF (29 consecutive years). Our citrus somatic hybridization program is the most successful in the world, resulting in somatic hybrid plants from more than 200 parental combinations. Our successes in somatic hybridization have allowed us to initiate rootstock breeding and selection at the tetraploid level (a completely unique approach), resulting in the selection of more than 150 superior individual hybrids called “tetrazygs” to date. Progress has also been made towards the development of rootstocks with improved tolerance of Diaprepes root weevil, blight and salinity. More recently, my program has focused on breeding, screening, and field testing new rootstocks (diploid and tetraploid) with focus on development of rootstocks suitable for ACPS (Advanced Citrus Production Systems) and that impart tolerance or resistance to HLB in grafted scions. Seventeen new UFR rootstocks from our program showing enhanced tolerance of HLB (as compared to commercial rootstocks) were recently fast-track released for use in the Florida Citrus Industry, including 7 tetraploids and 2 diploids developed in my program. Most recently, we have used a high throughput method to screen thousands of hybrid rootstock candidates for ability to impart HLB tolerance to grafted scions, and identified several promising candidates. Numerous tetraploid somatic hybrids that combine elite diploid scion material have been produced and several flowering somatic hybrids are being used as pollen parents in our triploid breeding program (under the direction of F. G. Gmitter). We have built the largest collection of quality monoembryonic diploid females and quality tetraploid pollen parents in the world. More than 20,000 triploid hybrids have been recovered from interploid crosses followed by embryo rescue, with a good percentage of these being fathered by somatic hybrids (in collaboration with FG Gmitter). Progress has also been made in the development of improved acid fruits (lemons and limes) and ornamental citrus; new seedless triploid lemon and lime selections have been approved for release. Somatic cybridization was used to create the recently released ‘Summer Gold’ grapefruit, that extends the grapefruit harvest season by several months, with fruit sweeter than any commercial grapefruit cultivar. This technology is also being used to transfer mtDNA potentially conferring canker resistance from kumquat to highly susceptible grapefruit cultivars. Because sweet oranges and grapefruit are not amenable to conventional breeding, my program has focused on the generation of somaclonal variation to produce new cultivars. We have the largest field study in the world to evaluate somaclonal variation in woody fruit trees. Several improved processing oranges have been released, including a Hamlin clone with improved juice color, seedless Valencia clones, Valencia clones with higher yields and lbs. solids production, the new very high quality OLL oranges that are showing better tolerance to HLB, and most recently two early-maturing Valencia clones that have potential to replace Hamlin in the juice industry. Working closely with research associate Dr. Manjul Dutt, we have developed an alternative citrus transformation method that utilizes a citrus anthocyanin gene for selection (replacing GFP) and plant recovery via somatic embryogenesis – resulting in transgenic plants containing no bacterial resistance genes (more consumer friendly). Major emphasis is now on the utilization of transgenic approaches to develop cultivars resistant to citrus greening (HLB) and canker. A major effort is underway to transfer proven anti-microbial peptide constructs and constructs that turn on SAR (Systemic Acquired Resistance) to citrus. Initial greenhouse and field challenges of transgenic citrus plants with HLB and canker look quite promising, and two SAR-induction genes are working successfully in multiple cultivars. Transgenic sweet orange trees overexpressing the Valencia β-1,3-glucanase gene also look promising. Our program is now focusing on the development of all-edible plant gene and eventually all-citrus gene transformation in efforts to increase consumer acceptance of GMO citrus.

CLAIRE LUBY


Claire is currently part time Executive Director of the Open Source Seed Initiative (OSSI) and part time Post Doctoral Researcher at the University of Wisconsin-Madison. She is a co-founder and board member of the Open Source Seed Initiative, which seeks to promote and maintain fair and open access to plant genetic resources through outreach, and an open source release mechanism for plant varieties. Claire is also a co-founder of the Student Organic Seed Symposium, now in its sixth year, which has created a community of graduate students and professionals working toward developing a more robust organic seed system. Her PhD as a Seed Matters Fellow in Organic Plant Breeding at the University of Wisconsin-Madison, focused on assessing genetic variation and freedom to operate in a large collection of U.S. carrot cultivars. Claire’s work asked whether the cultivars with “freedom to operate” in carrot breeding—that is, cultivars without intellectual property restrictions—represent an adequate portion of the total genetic variability of the crop. In addition, in collaboration with Prof. Irwin Goldman, Claire developed eight carrot populations based upon market and color classes using material that was not restricted by intellectual property and released them as OSSI-Pledged populations, thus providing ideal sources of material that all interested can use to breed new open source carrot varieties.
