Since its first edition in 1971, this triennial international meeting, held under the auspices of the Eucarpia association, is a fruitful forum for exchanges about the latest advances on Capsicum and eggplant genetics and breeding between c. 200 research and development experts from academic as well as private sectors. This 17th meeting is organized by INRA, as were its 3rd (1977) and 10th (1998) editions. The five scientific sessions, Genetic Resources and Domestication, Resistance to Biotic & Abiotic Stresses, Nutritional Value & Fruit Quality, Biotechnology & Genomics, and Pre-breeding & Breeding, illustrate the commitment of Capsicum and eggplant scientists to sustainable breeding and crop production. The scientific committee, together with the local organization committee, have introduced some new features into the 2019 meeting: - keynote speakers introduce each session with a talk providing an overview of each field of research; - the book includes abstracts of a standardized structure, instead of full papers, in order to provide complete and easy to handle information, and not to prevent subsequent publications in peer-reviewed journals; - authors of oral communications have been invited to write full original articles in the peer-reviewed and open-access journal ‘Crop Breeding, Genetics and Genomics’ (CBGG), which will publish a special issue on ‘Genetics and Breeding of Pepper and Eggplant’, - to promote participation of students in order to rejuvenate the Capsicum and Eggplant academic network, students have been offered reduced registration fees and awards will be attributed to the best oral and poster presentations of PhD students, thanks to public and private sponsorship; - free registration has been offered to a few PhD students and senior scientists from low-income countries, thanks to French institutional sponsorship. 6 Capsicum and Eggplant EUCARPIA Meeting 2019 | Foreword Innovations in Genetics and Breeding of Capsicum and Eggplant We thank all oral and poster authors for their contributions and the special efforts made to comply with the specified abstract format together with the revisions suggested by the scientific committee aiming at ensuring uniform scientific quality. Members of the international scientific committee are warmly thanked for their noteworthy involvement in the scientific organization of the meeting. We are grateful to the local organization committee that has accomplished a tremendous and versatile 2 years’ work. Our acknowledgements are also addressed to INRA, GEVES, CTIFL, Terralia, to several other national or regional French institutions, as well as to the vegetable seed companies, all of whose support and sponsorship was indispensable for the organization of the meeting. We hope all attendees will enjoy the 17th Eucarpia Meeting on Genetics and Breeding of Capsicum and Eggplant in Provence as much as the previous editions, and that this book will serve over the long term in testifying to its high scientific interest. Successive generations of researchers and breeders over almost 50 years have all paved the way to increased genetic knowledge and varietal improvement of Capsicum and eggplant. We spare a special thought for Alain Palloix, an active member of our scientific community until 2016, on the occasion of this 17th Eucarpia meeting held in Avignon, and look forward to the next meeting in three years.

In the Staphylococcus aureus bacterial strains evaluated, HWP/GBP AgNPs demonstrated effective bacteriostatic and bactericidal effect Silver nanoparticles against Staphylococcus aureus. Time kill results portrayed that HWP/GBP nano-silver exhibited comparable Anti-biofilm bactericidal potency on S. aureus. Anti-biofilm potential of HWP/GBP AgNPs displayed significant effects at sub Danio rerio MIC levels, by triggering 50% biofilm reduction of the food spoilage microbe S. aureus, inferring that the anti- biofilm outcome is not dependent on antibacterial result, and this was confirmed by SEM and fluorescence studies. Histopathological analyses of S. aureus infected zebrafish liver did not display any abnormality changes such as extensive cell death and degeneration, upon treatment with HWP/GBP AgNPs and the zero-valent silver nanoparticles were comparatively less toxic and more operative in restraining the bioburden in S.

Obtained results showed that compo- sition and level of metabolites as well as antioxidant activity in paprika samples varied greatly among different locations. For the first time, clear differences in the chemical composition of sweet and hot paprika obtained from two Hungarian wax pepper cultivars produced in three different states of the Eastern Danube region were determined. Averagely, paprika samples from Croatia had the highest carot- enoid content but the lowest levels of phenols and flavonoids. The hot paprika samples from Croatia had the highest content of capsaicin and dihydrocapsaicin. Thus, the results of this investigation indicate that bioactive compounds in paprika can vary greatly depending on their geographical origin.

Martin Tropical Research and Education Center (TREC), University of Florida, 18905 SW 280th Street, Homestead, FL 33031, USA; cgm@ufl.edu * Correspondence: dseal3@ufl.edu; Tel.: +1-305-246-7001 (ext. 368); Fax: +1-305-246-7003 Academic Editors: Michael J. Stout, Jeff Davis, Rodrigo Diaz and Julien M. Beuzelin Received: 8 December 2015; Accepted: 25 February 2016; Published: 4 March 2016 Abstract: Peppers (Capsicum spp.) are an important crop in the USA, with about 32,000 ha cultivated in 2007, which resulted in $588 million in farm revenue. The pepper weevil, Anthonomus eugenii Cano (Coleoptera: Curculionidae), is the most troublesome insect pest of peppers in the southern United States. It is therefore urgent to find different vulnerabilities of pepper cultivars, fruit and plants parts, fruit colors and sizes, and timing to infestation by A. eugenii. Also relevant is testing whether fruit length and infestation state affect fruit numbers, weights, and proportions of fruit that are infested. Counts of A. eugenii adults and marks from oviposition and feeding suggested that C. chinense Jacquin “Habanero” was least susceptible, and C. annuum L. cultivars “SY” and “SR” were most susceptible. Comparison of plant parts and fruit sizes revealed that A. eugenii preferred the peduncle, calyx, and top of pepper fruits over the middle, bottom, leaves, or remainder of flowers. Anthonomus eugenii does not discriminate between green or yellow fruit color nor vary diurnally in numbers. Based on adult counts, medium to extra-large fruits (¥1.5 cm long) attracted more weevils than small fruits (<1.5 cm).

  • Of Hot Peppers
    THE OF HOT PEPPERS COM . updated 03/2016 SUPER HOTS 800,000+ SHU Carolina Reaper 1,569,383 - 2,200,000 SHU As of August, 2013, Guinness World Records stated that Smokin’ Ed’s Carolina Reaper® is officially the world’s hottest chile pepper. The original cross was between two former world record holders, a ghost pepper and a Red Savina Habanero. Trinidad Moruga Scorpion 1,200,000 - 2,000,000 SHU The New Mexico State University’s Chile Pepper Institute identified the Trinidad Moruga Scorpion as the newest hottest chile pepper in the world as of February 2012. The Trinidad moruga scorpion has a tender fruit-like flavor, which makes it a deadly sweet-hot combination. 7 Pot/Pod Douglah (Trinidad Douglah) 923,000 - 1,853,396 SHU From Trinidad, it’s said that 1 pod will spice seven pots of stew. It is a rare and extremely hot chile. The Douglah is characterized by a dark brown/deep purple skin with many “pimples” over the surface. The pepper starts out green and matures to the dark color unique to the Douglah. 7 Pot Brown (Chocolate 7 Pot) 800,000 - 1,853,396 SHU There is still some debate as to whether the brown or chocolate 7 Pot is the same variety as the Douglah (above) while some contend that the 7 Pot Brown tastes much better than the Douglah. Ripe pods are brown in color, with the white internal membrane covering much of the inside of the pepper. 7 Pot Primo 1,473,480 SHU Created by Troy Primeaux, (nickname Primo), a horticulturist from Louisiana, the 7 Pot Primo can get very lumpy and distorted and even grow a skinny little tail.

They are prolific producers, come in all shapes, colors, sizes, and range in taste from mild bell peppers to flaming hot habaneros; and everything in between. Peppers are second in popularity, only to tomatoes. Although peppers are closely related to tomato plants, peppers are more demanding than tomatoes. Peppers require warm temperatures, need regular fertilization, and they need consistent moisture conditions to grow and produce an abundant harvest. Peppers don't just taste great; they look good too. Growing peppers in containers is easy, and most (if not all) peppers will thrive on a porch, deck or patio.

    5 Tasting ability in humans We must recognize that our mouth is very specific to tasting and interpreting the taste of specific foods items. Our mouth is full wit sensitive nerves which react and interpret very different even within an identical range of products, such as chilies As chilies have different “heats” or punchiness measured in the so called SCOVILLE SCALE our mouth nerves react in different places to establish the spiciness of such products Lips Left side Right side On the back top On the back bottom Tongue The 5 basic tasting senses are: Sweet, Salty, Sour, Bitter and Heat / Spiciness Scoville scale From Wikipedia, the free encyclopedia The Scoville scale is a measurement of the pungency (spicy heat) of chili peppers—such as the jalapeño, the bhut jolokia, and the world's current hottest pepper, the Carolina Reaper—or other spicy foods as reported in Scoville heat units (SHU),[1] a function of capsaicin concentration. Capsaicin is one of many related chemicals, collectively called capsaicinoids. The scale is named after its creator, American pharmacist Wilbur Scoville. His method, devised in 1912, is known as the Scoville Organoleptic Test.[2] Unlike methods based on high-performance liquid chromatography, the Scoville scale is a subjective measurement dependent on the capsaicin sensitivity of testers and so is not a precise or accurate method to measure capsaicinoid concentration.[citation needed] Considerations[edit] Since Scoville ratings are defined per unit of dry mass, comparison of ratings between products
