Cucumber mosaic virus (CMV) is one of the most dangerous viral diseases threatening Solanaceae crops, in particular Capsicum sp. This study aims to develop double haploid (DH) pepper lines from germplasm resistant CMV order speed up breeding process. For this purpose, six genotypes previously tested for resistance were used. Two induction mediums (17-2 and 17-3) with different concentrations 2,4-Dichlorophenoxyacetic acid (2,4-D) anther incubation further plant regeneration applied. L10 was...
Morphological variation in vegetative and fruit traits is a key determinant unraveling phenotypic diversity. This study was designed to assess diversity tomatoes examine intra- intervarietal groups' variability using 28 conventional descriptors (CDs) 47 Tomato Analyzer (TA) related plant morphometry. Comprehensive phenotyping of 150 accessions representing 21 countries discerned noticeable for CD TA quantified features, such as shape, size, color. Hierarchical cluster analysis divided the...
Selection of high-performance lines with respect to traits interest is a key step in plant breeding. Genomic prediction allows determine the genomic estimated breeding values unseen for trait using genetic markers, e.g. single-nucleotide polymorphisms (SNPs), and machine learning approaches, which can therefore shorten cycles, referring selection (GS). Here, we applied GS approaches two populations Solanaceous crops, i.e. tomato pepper, predict morphometric colorimetric traits. The were...
Abstract Background Due to global warming, the search for new sources heat tolerance and identification of genes involved in this process has become an important challenge as today. The main objective current research was verify whether determined controlled greenhouse experiments could be a good predictor agronomic performance field cultivation under climatic high temperature stress. Results Tomato accessions were grown three regimes: control (T1), moderate (T2) extreme stress (T3)....
Fruit shape significantly impacts the quality and commercial value of tomatoes (
Soil salinity is one of the abiotic stress factors gaining importance in recent years due to changing climate and rising temperatures. This possesses a serious risk food security worldwide range adaptations mitigation strategies are required. Crop improvement through breeding possible solution overcome stress. In this respect, study was designed screen collection from garden pea accessions tolerance vitro conditions. We analyzed effects four levels (0, 50, 100, 200 mM NaCl) on seed...
The in vitro response of anther cultures 19 Bulgarian pepper (Capsicum annuum L.) genotypes among which eight lines, seven varieties and four hybrids was examined using two induction media (C Cm) within time intervals for cultivation—12 40 days respectively, regeneration (R Rm). Six six three produced direct embryos the cultivated anthers 35–40 after inoculation vitro. Regenerated plants were obtained from one hybrid. It established that 12 cultivation on medium C not sufficient to initiate...
Characterization of local germplasm is an effective way to identify elite breeding material and develop improved varieties. This study was aimed assess 52 tomato accessions comprised varieties (28), landraces (8), lines (14), wild relatives (2), their characterization for 30 morphological/agronomic, four fruit quality, mosaic virus (ToMV) resistance traits. Morphological, ToMV traits were evaluated using phenotyping, biochemical assays, molecular markers, respectively. Fruit shape size...
Abstract The Balkan pepper breeding program aims to use in vitro embryogenesis (anther culture) develop doubled haploid lines with valuable traits. We analyzed the effectiveness of microspore on 17 genotypes comprised varieties, lines, and F 1 hybrids different varietal types (conical, bell shape, kapia) characterized agronomic traits newly generated lines. highest androgenic potential was observed variety Stryama line 560/06 9.55 13.00% reacted anthers, respectively. Of 186 regenerated...
This article summarizes the results of a research conducted to create an intelligent platform supporting small farmers growing vegetables. In Bulgaria, many use relatively areas for their production. Considering this situation, is designed regional use, trying make maximum specific climatic features monitored microdistrict. Consequently, special attention paid possibilities adapting environment in which observed plants grow. Thus, implemented as agent-oriented system providing needed...
The effect of different phytohormone concentrations on callusogenesis and organogenesis in two cucumber genotypes were studied. It was established that the rate plant regeneration depends genotype, explant type culture medium. Hypocotyls found to be more responsive than cotyledons morphogenesis. In vitro planlet-regenerants have been obtained hypocotyls explants medium with 1.0 2.0 mgL-1 BA for cultivar Gergana 3.0 mgL-1K-line 15B. Induction only supplemented combination 0.5 mgL-1IAA.
Tomato consumer liking results from the interaction between fruit's characteristics and human senses, shaped by diversity among consumers regarding physiology, culture past consumption experiences. Rather than a unique preference, can be segmented into different sensory clusters (sensoclusters). This study investigates European preferences for general-supermarket tomatoes compares them with renowned landraces in local markets. Based on of two focus groups, online surveys were designed to...
To create new varieties resistant to biotic and abiotic stress factors that possess high productivity improved fruit quality, breeders require modern breeding methods techniques. Double haploid (DH) lines are an invaluable element due their guaranteed, completely homozygous nature. One of the fastest for obtaining DH is anther culture. Microspore embryogenesis provides considerable opportunities in areas biotechnology represents a model system fundamental biological research. The...
The comparative breeding evaluation was carried out with six advanced pepper lines (Capsicum annuum L.) androgenic origin and their initial variety Hebar during the period 2008 - 2010 in field conditions at Plovdiv, Bulgaria. genotypes were characterized by total standard yield, plant height fruit traits: length, width, wall thickness weight. response of two (4 6) control to Verticillium wilt also investigated on artificial infected background. According results experimental work yield all...
Callusogenesis and regeneration ability of cotyledon hypocotyl explants from three Bulgarian pepper varieties in MS basal medium supplemented with l-3mg/l BAP. l.0mg/1 IAA 0.5mg/l GA3 was studied. In the different variants culture registered high level callusogenesis organogenesis both type all varieties. The highest percentage plant-regenerants is established (from 3.3 to 18.3) variant 3 containing 3mg/l BA. process micropropagation by stem same studied addition vitamins C. B12. Casein...
Anther or microspore culture induced haploid and double haploids (DH) are increasingly being utilized by breeders since it can shorten breeding time achieving complete homozygosity within a single generation. Pepper (Capsicum annuum L.) is one of the most important vegetables, distinguished its high level heterozygosity, making process very laborious long. Fourteen different DH lines were obtained as result anther four parental genotypes. Data from plant fruit morphological traits well...
