Target Audience:-Human sensory scientists -Plant breeders and biotechnologists -Plant producers -Plant shippers and handlers -Plant marketers -Food scientists -Consumers of plant-based food products ? Changes/Problems:The only major changes we have made recently is to do more conventional plant breeding instead of doing more basic laboratory research focused on molecular biology.This shift of efforts is not a shift of focus, but rather it is more an implementation of the information we have learned over the past decade. What opportunities for training and professional development has the project provided?Training opportunities -three undergraduate students obtained career jobs or moved on to PhD programs at major universities -four undergraduate students conducted internships at companies or government institutions -eleven undergraduate students are currently conducting focused research to support this project -nine undergraduate students presented research posters at national level plant breeding conferences -two graduate students are coducting PhD dissertation research to support this project How have the results been disseminated to communities of interest?-new cultivars have been released and licensed by the industry - these plants are now being sold to consumers in national retail stores -refereed journal articles are being published to allow the scientific community access to our research results. Our methods for consumer assisted selection have been adopted widely by university and corporate scientists -popular press coverage of superior performance of our new varieties at public field trials across the US has brought significant attention to our research program from the garden community -we have hosted public tours for approximately 10 different and diverse public groups -we continue giving more invited seminars from the US gardening community to discuss our research What do you plan to do during the next reporting period to accomplish the goals?-Continue the coleus breeding program to maintain the pipeline of introductions to the plant industry -continue expansion of our efforts in reeding and selecting new cultivars of downy mildew resistant sweet basil -continue growing our efforts in breeding and selection of new ornamental and edible garden plants.
Impacts
What was accomplished under these goals?
This project is now providing significant benefits to players in all aspects of the US horticultural supply chain. As a result of our efforts, plant scientist are gaining a better understanding of the biochemical components of flavor and fragrance in several different plant species. Producers and handlers of horticultural crops are now growing new varieties of plants produced from our work that have good commercial potential, as demonstrated by increased marketing and sales. US consumers are now planting and eating our new plants that look smell and taste better than many others in the marketplace. Main accomplishments: 12 new coleus cultivars were bred and released 1 new basil cultivar was brd and released 10 US plant patent applications were submitted through the Florida Foundation Seed Producers

Target Audience: The targeted audiences for this research project cover a broad range of fields related to all points in the supply chain forflowers, fruits and vegetables. Through the process of consumer-assisted selection, we first address consumers of specific plant crops/products to determine which traits they like best. We then communicate this information to plant scientists involved in plant breeding and biotechnology as a means to instruct them on the most impactful breeding targets. We also communicate with producers, shippers and supplies of these products, and provide information to consumer marketing experts. ultimately this information goes out to consumers and the public through various media formats. Changes/Problems: We see no major changes in this project in the year ahead. What opportunities for training and professional development has the project provided? This project has been the focus of research for one postdoctoral associate. One graduate student and two undergraduate students contributed to the most recent refereeed manuscript, and two other undergraduate students are now working on this project. How have the results been disseminated to communities of interest? Results from this project have been disseminated through the publication of a refereed manuscript. A press release of this work was taken forward from our institution, and a small number of media outlets ran subsequent stories on the topic. We have also recently created a small scientific writing group among the students working in our lab, and they will be working this next year to distill the results of this and other current work into forms more readily available for popular press and consumers. What do you plan to do during the next reporting period to accomplish the goals? The main goal of our project is to conduct research focused on bridging the gap between basic and applied plant science through the genetic improvement of various horticultural crops. We hope to expand our repertoire of high-value Florida crops and products being developed through the process of Consumer-assisted Selection beyond strawberry. We plan to go forward with similar basic and applied research on other important Florida crops such as blueberry, tomato, basil and ornamental plants such as coleus.
Impacts
What was accomplished under these goals?
The flavor of fresh strawberries is one of the most pleasurable of all fruits; comprised of simple sugars, a few organic acids, and a complex mixture of volatile compounds. As a result of our work individual sugars and acids were quantitated in fruit, as well as 81 volatile compounds potentially contributing strawberry flavor. Simultaneous to chemical inventory, 100 consumers rated each variety for its flavor intensity, sweetness, and overall liking. To expand the range and diversity of flavors and chemical constituents 35 genetic backgrounds were grown over two seasons. Analysis of this multidimensional data set revealed seasonal effects, gross variation across varieties, and fruit attributes influencing liking and sensory perception of strawberry fruit. Seasonal progression exerts a consumer perceivable, negative influence on sugar content in subtropical Florida, leading to decreased volatile content. The sweeter and more flavorful biochemical profile of early harvests is grounds for producers to demand premium prices. Interestingly, some of the most abundant volatiles do not contribute to consumer liking, whereas other less abundant volatiles significantly increase flavor intensity. In strawberry, we discovered a subset of specific volatiles that make contributions to perceived sweetness independent of sugar concentration in the fruit.
