Region-specific local landraces represent a germplasm diversity adapted and acclimatized to conditions, are ideal breed for targeted market niches while maintaining the variability of heirloom traits. A collection 180 pepper accessions, collected from 62 diverse locations across six Balkan countries, were characterized evaluated phenotypic biochemical variation during multi-year environment. An assortment 32 agro-morphological, fruit quality, virus resistance traits evaluated, top 10%...
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...
Capsicum (pepper) is among the most economically important species worldwide, and its fruits accumulate specialized metabolites with essential roles in plant environmental interaction human health benefits as well conferring their unique taste. However, genetics underlying differences metabolite presence/absence and/or accumulation remain largely unknown. In this study, we carried out a genome-wide association study generating characterizing novel backcross inbred line mapping population to...
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...
Information about the genetic variation among cultivars of vegetable crops is vital importance for improvement plant breeding programmes worldwide. The objectives this study were to group 19 pepper (Capsicum annuum L.) from collection Maritsa Vegetable Crops Research Institute, Plovdiv, Bulgariainto clusters according their distances as estimated by agronomic traits and 9 di-and tri -nucleotide inter simple sequence repeat polymorphism (ISSR) markers assess relationships between them....
There were investigated and compared the in vitro response anther culture of 16 Bulgarian pepper (Capsicum annuum L.) genotypes: six lines, varieties four hybrids developed Maritsa Vegetable Crops Research Institute, Plovdiv. The anthers reacted with induction direct embryogenesis or callusogenesis. Only two studied genotypes (line N145 variety Zlaten medal) have shown indirect organogenesis. established good embryogenic ability—varieties medal, Albena, Stryama, Hebur, Kourtovska kapiya, F1...
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...
Abstract The meiosis in the pollen mother cells (PMCs) of nuclear and nuclear-cytoplasmic male sterile (CMS) pepper lines No.1647 ms8ms8 No.K587 Srfrf was evaluated to establish causes sterility. investigations (ms8ms8 ) plants revealed that at diakinesis metaphase one, along with bivalents, up 4 quadrivalents, between 2 16 univalents were observed 21.2% 6.2% PMCs, respectively,. In remaining 72.6% normal pairing formation 12 bivalents found. Lethality occurred after second telophase, as...
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...
The comparative estimation was carried out with eight Serbian pepper varieties (Capsicum annuum L.) during the period 2010-2011 in field conditions at Maritsa Vegetable Crops Research Institute, Plovdiv, Bulgaria. were evaluated by some important morphological traits of plant and fruit, total marketable yield. assessment stem height showed proved differences between them. Romansa Ekstaza formed significantly longer fruits than other while Amanda lowest values this trait but highest ones...
Pepper fruit contain carotenoids, vitamins and other biological active substances which determine their health effect. The research work at the Maritsa Vegetable Crops Research Institute, Plovdiv is aimed to create lines, cultivars hybrids with higher quality. During period 2006–2007, ten pepper mutant genotypes used in beta-carotene breeding programme are investigated by plant quantitative characters on experimental field Institute. Three of them possess red botanical maturity ones, orange...
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...
Pepper (Capsicum annuum L.) is one of the most important vegetable crops worldwide. The Balkans, including Bulgaria, are considered as secondary centre pepper diversity especially for C. annuum, where local forms with diverse phenotypes and qualities have formed due to specific agro-climatic conditions breeding traditions. Evaluation genetic structure a collection an tool further development new varieties maintenance sustainable agriculture. In this study, set 179 accessions collected from...
This study was designed to assess the androgenic potential of 180 pepper accessions and 11 progenies (four F1 seven BC) possessing PMMoV resistance in order complement an ongoing breeding program. The experiment carried out 10 replications with 20 anthers for each accession two different induction mediums from 2017 2019. highest response observed culture medium 17-2 but differences between were nonsignificant. From a total 191 genotypes, 102 genotypes expressed direct embryogenesis. Embryo...
