Hybrid breeding relies on the combination of parents from two differing heterotic groups. However, genetic diversity in adapted oilseed rape material is rather limited. Therefore, use resynthesized Brassica napus as a distant gene pool was investigated. Hybrids were derived crosses between 44 lines with diverse background and male sterile winter tester lines. The hybrids evaluated together their check cultivars 2 years five locations Germany. Yield, plant height, seed oil, protein content...

Resynthesized Brassica napus L. could be employed to increase the genetic variation in narrow oilseed rape genepool and establish a genetically distant for hybrid breeding. One important criterion selecting appropriate resynthesized lines is their distance adapted breeding material.

ABSTRACT Genetic variation in N uptake and utilization was investigated a set of genetically diverse oilseed rape ( Brassica napus L.) genotypes, including hybrid, modern, old cultivars resynthesized lines. A total 36 genotypes were grown at seven locations with two levels supply: no fertilization optimal (between 160 220 kg ha – 1 N, depending on regional recommendations). The hybrid had the highest yields land races lines lowest yields. This ranking various groups consistent independent...

Resynthesized (Resyn) Brassica napus L. can be used to broaden the genetic diversity and develop a heterotic genepool for rapeseed hybrid breeding. Domesticated vegetable types are usually employed as B. oleracea parents. We sought evaluate potential of wild species parents Resyn lines. Fifteen lines were derived by crossing ssp. oilseed rapa, 29 generated from 10 (B. bourgaei, cretica, incana, insularis, hilarionis, macrocarpa, montana, rupestris, taurica, villosa). Genetic distances...

Abstract Key message Grain yield and NUE increased over time while nitrogen did not drop significantly despite reduced input. Selection for grain is equivalent to selection NUE. Breeding registration of improved varieties with high yield, processing quality, disease resistance use efficiency (NUE) are utmost importance sustainable crop production minimize adverse environmental impact contribute food security. Based on long-term variety trials cereals, winter oilseed rape peas tested across a...

In hydroponically grown Lycopersicon esculentum (L.) Mill. cv. F144 the site of NO3− reduction and assimilation within plant was shifted from shoot to root by salinity. Uptake solution strongly inhibited salinization. Consequently, concentrations in leaf, stem tissues as well nitrate reductase activities leaves were lower salinized than control plants. Lower NO3−, but higher reduced-N, observed xylem sap a result enhanced participation K+ leaf malate found compared plants which indicates...

The objective study was to investigate influence a major change oleate on palmitate content. An oilseed rape doubled haploid (DH) population n = 60) segregating one gene mutation, that increases by 11%, used field experiment five environments. Subdividing DH lines into normal high classes showed mutation caused significant reduction stearate ratio total C16...

Near-infrared reflectance spectroscopy (NIRS) of intact seeds allows the non-destructive estimation seed quality parameters which is highly desirable in plant breeding. Together with yield, oil content and quality, a main aim safflower (Carthamus tinctorius L.) breeding selection genotypes low percentage empty even under cooler climates. We developed NIRS calibrations for content, oleic linoleic acid hull fraction using meal seeds. For different 108-534 samples from program lines adapted to...

In cereals like wheat ( Triticum aestivum L.) or rice Oryza sativa L.), a short‐straw ideotype is characteristic for all modern cultivars, mainly due to the use of genes affecting dwarf genotype. oilseed rape Brassica napus several mutants are known but so far not widely used. An interesting approach production semi‐dwarf hybrids from and normal‐type parents, which might have an increased harvest index (HI) higher grain yield, especially when nitrogen (N) availability restricted. To this...

A higher nitrogen (N) use efficiency is an important breeding goal in crops such as oilseed rape ( Brassica napus L.) that are considered less N efficient compared with like wheat Triticum aestivum or barley Hordeum vulgare L.). Changes the plant ideotype, reduced height of semi‐dwarf hybrids, said to result increased harvest index and index. This could lead a efficiency, especially when availability restricted. double haploid population was developed segregating for bzh dwarf locus, 54...

Rapeseed (Brassica napus, AACC) was formed by hybridization between progenitor species Brassica rapa (AA) and oleracea (CC). As a result of limited number events specific genotypes strong breeding selection for oil quality traits, rapeseed has genetic diversity. The production resynthesized B. napus lines via interspecific the diploid is one possible way to increase variation in rapeseed. However, most produced so far have been reported be meiotically unstable infertile, contrast established...

Abstract Winter oilseed rape, with high oleic (HO) acid contents (C18:1) is of interest for nutritional as well industrial purposes. HO mutants have been described, but only limited information available on any environmental influence the expression content in these mutants. Therefore, a population 60 doubled‐haploid (DH) lines segregating (56‐75% C18:1) was grown two years at three locations northern Germany. Analysis variance revealed heritability h 2 = 0.99. Subdividing DH into (> 64%...

In oilseed rape (Brassica napus) semi-dwarf hybrid varieties from crosses between bzh dwarf and normal-type lines are of increasing interest. They have improved nitrogen (N) uptake, N-utilization N-use efficiency compared to normal types. This study aimed elucidate whether these N-related effects can be explained by the shoot growth-type alone or also differences in root traits.Root system size was measured using electrical capacitance (EC) field trials with two N levels sets genotypes...

Abstract Ascochyta fabae is a fungal pathogen responsible for marked yield losses in spring and winter faba beans worldwide. The aim of this genome‐wide association study (GWAS) using 188 diverse bean inbred lines was to exploit earlier blight resistance studies identify new loci. Phenotyping after artificial inoculation under controlled conditions revealed significant variation all eight scored disease traits. This GWAS based on 1829 AFLP marker 229 SNP marker, including 17 so‐called...

The aim of this study was to analyse the impact heterozygosity and heterogeneity levels plant height ability genotypes. A set 24 genotypes, classified as genotype groups (eight inbred lines, eight polycross progenies, two line bulks, hybrid bulks four controls), tested under treatments: with without model weed. Each group...

Established allopolyploids are known to be genomically stable and fertile. However, in contrast, most newly resynthesized infertile meiotically unstable. Identifying the genetic factors responsible for genome stability formed allopolyploid is key understanding how 2 genomes come together form a species. One hypothesis that established may have inherited specific alleles from their diploid progenitors which conferred meiotic stability. Resynthesized Brassica napus lines often unstable...

Winter oilseed rape ( Brassica napus L.) with a high oleic (>75%) and/or low linolenic acid (∼2%) content in the seed oil is of interest for nutritional and technical purposes.
