The world demographic growth and global climate change are major challenges for human society,hence the need to design new strategies for maintaining high crop yield in unprecedented environmental conditions.The objective of TomGEM is to design new strategies aiming to maintain high yields of fruit and vegetables at harsh temperature conditions, using tomato as a reference fleshy fruit crop.As yield is a complex trait depending on successful completion of different steps of reproductive organ development, including flower differentiation and efficient flower fertilization,TomGEM will use trans-disciplinary approaches to investigate the impact of high temperature on these developmental processes.The core of the project deals with mining and phenotyping a vast range of genetic resources to identify cultivars/genotypes displaying yield stability and to uncover loci/genes controlling flower initiation,pollen fertility and fruit set.Moreover,since high yield and elevated temperatures can be detrimental to quality traits,TomGEM will also tackle the fruit quality issue.The goal is to provide new targets and novel strategies to foster breeding of new tomato cultivars with improved yield.The main strength of TomGEM resides in the use of unique and unexplored genetic resources available to members of the consortium.It gathers expert academic researchers and private actors committed to implement a multi-actor approach based on demand driven innovation.Tomato producers and breeders are strongly involved from design to implementation of the project and until the dissemination of results.TomGEM will provide new targets and novel strategies to foster the breeding of new tomato cultivars with improved yield under suboptimal temperature conditions.TomGEM will translate scientific insights into practical strategies for better handling of interactions between genotype,environment and management to offer holistic solutions to the challenge of increasing food quality and productivity.

Variability has been studied and a comparative evaluation has been made of the basic traits connected with the seed-productivity in the fruit of intravarietal hybrids of tomatoes and their parental lines. The research was conducted at the Maritsa VCRI, Plovdiv during the period of 2005-2008. The variance of the indicators average weight, average number of seeds in one fruit and the absolute weight of seeds of the large-fruit parental varieties is higher than the small-fruit ones. The hybrid combinations of tomatoes hardly vary from their parental forms as referring to the variance of average number of seeds in the fruit, number of seeds in 1g of fruit and absolute weight of seeds. The average number of seeds in 75% of hybrid combinations is bigger than those of the parental line, and in 25% it is smaller than the parental forms with greater number of seeds but it is not smaller than the female one. The number of seeds in 1g of fruit in F1 hybrid combinations of tomatoes is significantly larger than those of the parental forms. Only in two of the hybrid combinations Bela x Roma and Venera x Roma the absolute weight of the seeds is smaller both compared to the female and the male lines. The achieved results give us a reason to conduct a successful breeding in accordance with these traits in order to create hybrids with lower seed-productivity by a precise choice of parental couples.

Boiled potatoes from twelve cultivars grown at two altitudes were evaluated for appearance, aroma, colour, texture, friability, starch taste, sweetness, sourness and overall taste. Correlation analysis was applied to estimate the significance of the sensory traits for the whole human perception. It was found that the total sensory evaluation was in correlation at the highest degree with taste (average r = 0.800), followed by texture (average r = 0.679), colour (average r = 0.617) and appearance (average r = 0.614). Their assessment during the breeding process has to be taken into account in order to create high quality potato cultivars. The lack of significant correlations between identical sensory traits of potatoes grown under field and mountain conditions is a proof for impossibility to predict sensory profile of boiled potatoes by results from only one altitude. © 2015, National Centre for Agrarian Sciences.

Optimization of growth, yield and quality of vegetable crops in an integrated manner is achievable through efficient use of organic, inorganic and biological sources of nutrients. The present study aimed to evaluate the effect of foliar or soil application of humic and bio-fertilizers, on the growth and yield of greenhouse tomatoes. The experiment was carried out during three consecutive years in an unheated greenhouse at Maritsa Vegetable Crops Research Institute, Bulgaria. A commercially available humic fertilizer, produced from vermicompost, and biofertilizer, containing Lactobacillus casei, Lactobacillus lactis, Phodopseudomonas palistris, Saccharomices cerevisiae were tested. Soil application of both fertilizers was performed only once, a week after transplanting, while the foliar application was conducted three times with 10-14 day intervals after transplanting. In order to assure uniform background of the experimental plots, the soil was supplemented with mineral fertilizers according to the recommendations following the soil analysis. The results indicated that soil application of both fertilizers stimulated the growth of tomato plants. The total tomato yield was increased with 19 and 21% after soil application and by 13 and 14% after foliar application of bio-fertilizer and humic fertilizer, respectively. The enhancement of the total yield was attributed to the enhancement of the mean fruit weight, which increased by 14-30 g per fruit. The early yield and the number of fruits per plant were not influenced by the applied humic or bio-fertilizers. The results indicated that the utilization of bio-fertilizer or humic fertilizer in fertilization practices can lead to higher yield of greenhouse tomato with improved market quality.

Greenhouse tomato production in Bulgaria is extremely energy intensive; therefore the majority of producers grow tomatoes in greenhouses without heating. The aim of the research was to improve the tomato production energy effectiveness by using new technology conventional fertilization based on soil analysis and novel biofertilizers instead of manure. Two biofertilizers were used bacterial fertilizer BioLife (USA) and mycorrhizal inoculum Media Mix (USA). The application of biofertilizers to improve soil fertility combined with optimized use of synthetic fertilizers can increase the energy output with the yield which leads to an increased energy output-input ratio to 1.19 and 1.11 respectively. The energy output with the yield exceeds the energy inputs and energy gains of 19.45 GJ.ha-1 and 11.40 GJ.ha-1 are achieved. The results show that the total energy output (90.52 GJ.ha -1) increased by 32.0% when BioLife was used and by 22.9% when Media Mix was used. Bacterial fertilizer, mycorrhizal inoculum and tomato fruits energy equivalents of 0.01 MJ.kg-1, 14.5 MJ.kg-1and 1.2 MJ.kg-1 respectively have been established to allow an energy assessment of tomato production.

Pepper (Capsicum annuum L.) is an important vegetable crop that can be improved using plant tissue culture and biotechnology. However, it is difficult to develop appropriate breeding material by in vitro cultivation in this species. Haploid plant production is useful in the breeding programs to facilitate recovery of recessive mutations and unique genetic recombinations. In embryogenesis, haploid formation from pollen in anther culture is a scientifically advanced, but controversial system. Various techniques for haploid plant regeneration are used to establish an efficient double haploid production method. The purpose of this article is to summarize, through comparison, results in pepper anther culture, problems associated with work in this field, and the influence of critical factors for successful embryo formation and plantlet development. © 2011 Franciszek Górski Institute of Plant Physiology, Polish Academy of Sciences, Kraków.

Bean common mosaic virus (BCMV) and Bean common mosaic necrosis virus (BCMNV) are among the biggest threats for snap bean production in Bulgaria due to their seed, aphid and mechanical transmission. Old valuable Bulgarian snap bean varieties are being neglected, because of the high percentage of virus-infected seeds. Breeding resistant cultivars is the best way to solve the problem. The genetic control towards both viruses is assured by one dominant I gene and a number of recessive (bc-u, bc-1, bc-12, bc-2, bc-22 and bc-3) genes. Our aim was to identify resistance gene combinations in advanced F8 breeding lines, derived from two crosses (A-8-40-7-2-1 × IVT 7214) and (Zaria × RH 26D), by the application of conventional and molecular approaches. Four methods were applied for the characterization of their resistance gene makeup: (i) leaf-abscission infection test designed to identify I gene by direct inoculation with NL3 strain of BCMNV; (ii) intact-plant infection test with strain NY15 of BCMV to separate immune genotypes, possessing bc-ubc-12, bc-ubc-22,bc-ubc-2bc-3, I, Ibc-12, Ibc-22 or Ibc-3; (iii) PCR analysis with the following markers: SCAR - SW13 (for I gene), SBD5 (for bc-12), ROC11 (for bc-3) and CAPS - eIFE4 (for bc-3); and 4) high-temperature (more than 30°C) infection test with NL3 of BCMNV to provoke systemic necrosis in I, Ibc-1, Ibc-12, Ibc-12bc-22 or Ibc-3. The four methods applied worked properly and complemented each other. Valuable gene combination (Ibc-3) was established in seven breeding lines with immune reaction to BCMNV. They will be included in the snap bean breeding programme for virus resistance. © 2013 Blackwell Verlag GmbH.

Despite the adoption of several reform programs Bulgaria still has the lowest research and innovation index of all EU Member states. Key reasons for Bulgarias comparatively poor record of innovation are the insufficient investment in R&D, fluctuating labour force, the almost non-existent linkages between research and the needs of the productive sector and a lack of high-tech science and business parks. With the newly released Smart Specialization Strategy (S3) Bulgaria has an unparalleled opportunity to transform itself into a knowledge-based and R&D-led economy and to turn its research system into an engine of innovation and smart specialization. Plant systems biology, biotechnology, and healthy life have been set in the S3 as top priorities and represent research topics, which are highly addressed in Plovdiv, the biggest academic center in Southern Bulgaria and the most important agricultural region within the country. Most local research units are very productive and competitive at international level harbouring a huge academic and business potential. The goal of the project is to establish a Center of Plant Systems Biology and Biotechnology (CPSBB) in Plovdiv, which will stand at the forefront of plant sciences in Bulgaria. Building on the excellence in plant sciences and biotechnology research of Potsdam, Germany, the CPSBB will implement cutting-edge genetics, functional genomics, metabolomics and bioinformatics technologies to unravel the plant biochemical machinery and translate the scientific knowledge into the food market and industrial applications for development of value-added products with potential markets in medicine, pharmacy and cosmetics. The CPSBB will provide the missing links between academia and industry in the region and will take a leading role in educating next-generation researchers in the fields of plant systems biology and biotechnology. Thus, the CPSBB will fill the scientific and technological gaps identified in the S3 of Bulgaria.
