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.

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.

The initiatives of the project aim to support the progress of Maritsa Vegetable Crops Research Institute to be reinforced as a modern, competitive one in European horticultural science and to become a leading research center for Balkan region. Coordination and Support Actions proposed here comprise: 1) Recruitment scientists from leading European Institutes to transfer the recent achievements of European knowledge of plant genetics diversity, pest risk analysis, plant nutrition and organic production; 2) Enhancement the professional level of young researchers and exchange of know-how and experience for senior scientists in relevant advanced European Institutes; 3) Improvement and up grading the technical status of Institute with new trends equipment; 4) Establishment of Maritsa VCRI as a dissemination centre and promoter of European knowledge and practice in the field of vegetable science in Bulgaria as well as in Balkan region; 5) Support of Maritsa Technology Transfer Office as an innovative centre and as an interface between the Institute and farmers and processors to transfer the advanced European technologies. The potential impacts will be: 1) acquaintance of Bulgarian researchers with the latest achievements in management of vegetable resources, pest risk analysis and soil fertility management, 2) creation of new generation of young researchers, experienced in high level management of vegetable resources, 3) achievement of comparable and competitive level to the ERAs due to the improvement of technical status of Institute, 4) elaboration of strategy for Bulgarian vegetable science and development of the Institute as an advisory and dissemination Centre, 5) reinforcing the Balkan collaboration to bring together expertise of different disciplines for preservation and proper management of vegetable diversity in Balkan region. All support and coordination actions will be performed in collaboration with the prestige European research institutes.

G2P-SOL is a research alliance bringing together the major European and International repositories of germplasm with public and private institutions active in genomics, phenotyping and breeding in the four major Solanaceous crops: potato, tomato, pepper and eggplant. These four crops constitute 66% of the value of European horticultural production, and over 65,000 accessions are available within the consortium. By harnessing the available global biodiversity, novel genotyping and phenotyping concepts and data analysis tools, the G2P-SOL project will link the genetic code underlying Solanaceae biodiversity with the traits that improve productivity, adaptation and human health. By making this information accessible to end-users, the awareness of the available diversity will be increased and use of this genetic diversity in breeding programs will be stimulated, resulting in diversified production chains. The phenotypes and traits of material held in European and major international collections will be described using common ontology terms developed in this project and this information will be housed in an open source software platform, allowing easy interfacing with existing platforms for germplasm cataloguing. G2P-SOL will develop shared values in science and education in the following areas: 1) Defining and maintaining genetic pools for crop improvement. 2) Phenomic and genomic data: generation, analysis, storage, and linkage with gene banks. 3) Pre-breeding and germplasm enhancement. 4) Training, workshops and public outreach. G2P-SOL will redefine how to manage and organize genetic resources and linked genomic and phenomic information in a manner that will make them accessible to naturalists, geneticists and breeders for conservation, scientific research, and breeding in the post genomic era, in compliance with the objectives of the International Treaty on Plant Genetic Resources and the Nagoya Protocol.

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.
