    TRADITION, QUALITY AND BIOTECHNOLOGY IN HUNGARIAN SPICE PEPPER (Capsicum annuum L.) BREEDING

    No full text
    Spice pepper production has a history of almost 300 years in the southern part of Hungary. In this study the results of two biotechnological improvements are summarized. Anther and isolated microspore culture techniques were improved to release haploid and doubled haploid (DH) lines for spice pepper breeding. Both the anther and isolated microspore culture methods were successfully used in spice pepper haploid production. Microspore culture- derived structures were analysed to identify their different parts. Green plantlets were regenerated from embryos derived from both anther and microspore cultures. Their doubled haploid analogues were integrated into Hungarian spice pepper hybrid seed breeding programmes. One hybrid, Sláger, was released as a new genotype for spice pepper production in 2008 and two hybrid candidates (Délibáb and Bolero) are now being tested in official trials

    EFFECTS OF AGRONOMIC VARIABLES AND HINERITANCE ON AROMATIC COMPONENTS IN BASIL AND CHILI PEPPER

    No full text
    This PhD Thesis focuses on how aroma profile in crops is affected by agronomic and genetic variables. In the first chapter we considered the effects of salt stress on main morphological and physiological traits of two cultivars of sweet basil (Genovese and Napoletano) Specifically, we focused on compositional changes in aroma profile and their possible significance in adaptation and tolerance to the oxidative stress. In the second chapter, we considered the aroma profile of two chilli pepper species, Habanero (Capsicum chinenese) and Jalapeño (Capsicum Annuum), at different stages of maturity. Moreover, preliminary results of genetic mapping process were introduced. Part of this research has been conducted at University of California-Davis (USA)

    Transcript (72 pages) of interview by Leslie Kelen with Sonia Pepper with additional comments from Rose Arnovitz on January 14, 1983 for the Interviews with Jews in Utah Oral History Project.In this interview with Leslie Kelen, Rose Arnovitz is present, as indicated by the initials RA. Sonia Pepper begins by discussing her parents, childhood, education, and work as a young adult. She also talks about collecting for the Jewish Relief Society, the inner workings of that group, the Jewish community in Salt Lake, being involved of the remodeling of Montefiore, and the role of women in the Jewish community. Pepper and Rose talk about the merger of the congregations, the James L. White Jewish Community Center, the United Fund, their social lives, other community members, and programs helping transients. 72 pages

    Androgenesis induction in microspore culture of sweet pepper (Capsicum annuum L.)

    No full text
    Isolated microspore culture experiments were carried out in sweet pepper (Capsicum annuum L.) F1 hybrid genotypes. In the first experiment, four culture media (W14, B5, MS and NLN) were compared to test their effectiveness in inducing the formation of microsporederived structures in two genotypes. The experiments revealed the superiority of B5 medium. In the second experiment, the effects of different ratios of 2,4-dichlorophenoxyacetic acid (2,4-D) (0, 0.1, 0.2 and 0.5 mg l-1) and kinetin (0, 0.2 and 0.5 mg l-1) were also investigated in B5 medium with two genotypes. The effect of growth regulators were investigated on the production of microsporederived calli and embryo-like structures (ELSs), the ratio of the two and plant regeneration (number of regenerated plantlets) in microspore culture. The histological experiments revealed the differences between the microsporederived ELSs and calli. The most promising results were obtained on the investigated parameters in the presence of 0.1 mg l-1 2,4-D and 0.2 mg l-1 kinetin producing the highest number of plantlets in both genotypes tested. In the response of 11 genotypes, the androgenesis induction was successful in each sweet pepper genotypes tested using the best basic medium and growth regulators combination. In case of 11 genotypes, the number of ELSs ranged from 20 to 100/Petri dish (an average of 48.1 ELS/Petri dish), while the number of green plantlets varied from 0 to 8 plantlets/Petri dish (an average of 1.5 plantlets/Petri dish) depending on the genotype. The spontaneous rediploidization rate obtained was 25% in isolated microspore

    Pepper-pot emittance measurement of laser-plasma wakefield accelerated electrons

    No full text
    The transverse emittance is an important parameter governing the brightness of an electron beam. Here we present the first pepper-pot measurement of the transverse emittance for a mono-energetic electron beam from a laser-plasma wakefield accelerator, carried out on the Advanced Laser-Plasma High Energy Accelerators towards X-Rays (ALPHA-X) beam line. Mono-energetic electrons are passed through an array of 52 mu m diameter holes in a tungsten mask. The pepper-pot results set an upper limit for the normalised emittance at 5.5 +/- 1 pi mm mrad for an 82 MeV beam

    Exploratory QTL analyses of some pepper physiological traits in two environments

    behind phenotypic differences and led to selection of genotypes having favourable traits. Continuous monitoring of environmental conditions has also become an accessible option. Rather than single trait evaluation, we would prefer smarter approaches capable of evaluating multiple, often correlated and time dependent traits simultaneously as a function of genes (QTLs) and environmental inputs, where we would The use of molecular breeding techniques has increased insight into the genetics like to include intermediate genomic information as well. In this paper, an exploratory QTL analysis over two environments was undertaken using available genetic and phenotypic data from segregating recombinant inbred lines (RIL) of pepper (Capsicum annuum). We focused on vegetative traits, e.g. stem length, speed of stem development, number of internodes etc. We seek to improve the estimation of allelic values of these traits under the two environments and determine possible QTL x E interaction. Almost identical QTLs are detected for each trait under the two environments but with varying LOD scores. No clear evidence was found for presence of QTL by environment interactions, despite differences in phenotypes and in magnitude of QTLs expression. Within the EU project SPICY (Voorrips et al., 2010 this issue), a larger number of environments will be studied and more advanced statistical analysis tools will be considered. The correlation between the traits will also be modelled. The identification of markers for the important QTL (Nicolaï et al., 2010 this issue) will improve the speed and accuracy of genomic prediction of these complex phenotype

    Biomimetic total synthesis of (+)-merochlorin A

    No full text
    Inspired: The proposed biosynthetic pathway toward the potent antibiotic meroterpenoid (±)-merochlorinA inspired its concise total synthesis. The key steps in the synthesis are a one-pot aromatization-alkylation reaction, followed by a biomimetic oxidative dearomatization of a highly functionalized naphthalene derivative, which forms two rings and four contiguous stereocenters in a single step.
