The main objective in this research was the genetic analysis of heterosis rapeseed at QTL level. A linkage map comprising 235 SSR and 144 AFLP markers covering 2045 cM constructed a doubled-haploid population from cross between cultivar "Express" resynthesized line "R53." In field experiments four locations Germany 250 (DH) lines their corresponding testcrosses with Express were evaluated for grain yield three components. ranged 30% to 0.7% kernel weight. mapped using different data sets,...
Little is known about the genetic control of heterosis in complex polyploid crop species oilseed rape (Brassica napus L.). In this study, two large doubled-haploid (DH) mapping populations and corresponding sets backcrossed test hybrids (THs) were analysed controlled greenhouse experiments extensive field trials for seedling biomass yield performance traits, respectively. Genetic maps from populations, aligned with help common simple sequence repeat markers, used to localise compare...
Abstract Key message We identified marker-trait associations for key faba bean agronomic traits and genomic signatures of selection within a global germplasm collection. Faba ( Vicia L.) is high-protein grain legume crop with great potential sustainable protein production. However, little known about the genetics underlying trait diversity. In this study, we used 21,345 high-quality SNP markers to genetically characterize 2678 genotypes. performed genome-wide association studies using...
Linkage disequilibrium was investigated in canola quality winter rapeseed to analyze (1) the prospects for whole-genome association analyses and (2) impact of recent breeding history on linkage disequilibrium. A total 845 mapped AFLP markers with allele frequencies ≥0.1 were used analysis a population 85 genotypes. low overall level found mean r 2 only 0.027 over all 356,590 possible marker pairs. At significance threshold P = 2.8 × 10−7, which derived by Bonferroni correction from global...
Abstract The objective of the present study was to estimate abundance and degree polymorphism simple sequence repeat (SSR) markers in rapeseed. By screening about 45000 clones a small inserts library rapeseed total DNA abundances GA/TC CA/TG repeats genome were estimated be approximately one every 100 kb 400 kb, respectively. After sequencing 13 positive clones, primer pairs could designed for 11 microsatellite loci. Seven these produced reproducible amplification products set 31 genotypes,...
Abstract Tocopherols are natural antioxidants in vegetable oils and important dietary nutrients. Enhanced tocopherol content has become an objective oilseed rape breeding. A segregating DH population was tested for 2 years at two locations replicated field trials. Genotypic differences occurred α‐, γ‐ total as well α/γ‐tocopherol ratio, but highly significant genotype x environment interactions resulted low heritabilities. Using a mixed‐model composite interval mapping approach between one...
Rapeseed (Brassica napus L.) is one of the most important oilseed crops both in Europe and China. The objective this study was to investigate whether European Chinese gene pools winter rape contain different alleles for high seed oil content. A linkage map rapeseed comprising 125 SSR markers covering 1196-cM genome length constructed from an F1 derived doubled haploid (DH) population a cross between German cultivar Sollux Gaoyou, selected In total, 282 DH lines were evaluated replicated...
Improving oil and protein quality for food feed purposes is an important goal in rapeseed (Brassica napus L.) breeding programs. Rapeseed contains phytosterols, used to enrich products, sinapate esters, which are limiting the utilization of proteins industry. Increasing phytosterol content lowering ester meal could increase value oilseed rape crop. The objective present study was identify quantitative trait loci (QTL) a winter population 148 doubled haploid lines, previously found have large...
QTL mapping by association analysis has recently gained interest in plant breeding research as an alternative to segregating populations from biparental crosses. In a first experiment on whole-genome rapeseed, 684 mapped AFLP markers were tested for with 14 traits set of 84 canola quality winter rapeseed cultivars. For general linear model was used. By testing significance marker–trait associations against false discovery rate 0.2, between 1 and 34 associated found 10 the traits. Taking into...
Abstract The applicability of random amplified polymorphic DNA (RAPD) markers in the cultivated rubber tree, Hevea , was evaluated using 43 decamer oligonucleotide primers a set 24 clones selected different South‐East Asian countries. A total 220 0.35–3.5 kb fragments were amplified, which 111 polymorphic. Of these, 80 (RAPD markers) repeatable and clearly scorable across all genotypes used to estimate genetic distances among tested. estimated ranged from 0.05 (RRII 308 PB 5/51) 0.75 (RRIC...
Abstract The versatility of faba bean Vicia grain as valuable protein feed is hampered by its relatively high level the compounds vicine and convicine (VC), which are antinutritive factors in poultry other non‐ruminants. objective this study was to fine‐map major locus for VC and, based on this, develop a novel low‐VC winter bean. Bi‐parental F 2 ‐families isogenic lines three different genetic backgrounds were used linkage‐mapping collect transcriptomic data. Furthermore, synteny Medicago...
Seven intervarietal substitution lines were identified with embryogenic potentials up to 40.4 times that of the recurrent parent, providing an ideal material for further in depth studies this trait. To identify genomic regions carry genetic factors controlling potential isolated microspores rapeseed, marker segregations analysed a segregating population haploid microspore-derived embryos and BC1 from cross between 'Express 617' 'RS239'. After map construction 15 same as parent selected donor...
Abstract Faba bean ( Vicia faba L.) is a high-protein grain legume crop with great potential for further cultivation. However, little known about the genetics underlying trait diversity. In this study, we use 21,345 high-quality SNP markers to genetically characterise 2,678 genotypes. We perform genome-wide association studies of key agronomic traits using Seven-parent-MAGIC population and detect 238 significant marker-trait associations linked 12 importance, 65 these being stable across...
