We have developed a dense reference genetic map of Lupinus angustifolius (2n = 40) based on a set of 106 publicly available recombinant inbred lines derived from a cross between domesticated and wild parental lines. The map comprised 1090 loci in 20 linkage groups and three small clusters, drawing together data from several previous mapping publications(More)
This is the first clear evidence of duplication and/or triplication of large chromosomal regions in a genome of a Genistoid legume, the most basal clade of Papilionoid legumes. Lupinus angustifolius L. (narrow-leafed lupin) is the most widely cultivated species of Genistoid legume, grown for its high-protein grain. As a member of this most basal clade of(More)
Genome size was measured in 75 samples of the wild pea species Pisum abyssinicum, P. elatius, P. fulvum and P. humile by ethidium-bromide (EB) flow cytometry (internal standard: Triticum monococcum) and Feulgen densitometry (internal standard: Pisum sativum ‘Kleine Rheinländerin’). Total variation of EB-DNA between samples covered 97.7% to 114.9% of the P.(More)
Identification of individual chromosomes in Lupinus is not possible due to gradient in size and similar morphology. To overcome this problem, molecular cytogenetics was developed for Lupinus. As an initial step in karyotype analysis, fluorescent in situ hybridization (FISH) was performed to determine genomic distribution of rRNA genes in L. hispanicus, L.(More)
A linkage map of pea was constructed based on a 104 RIL population derived from the cross combination Wt10245 x Wt11238. The map, which consisted of 204 morphological, isozyme, AFLP, ISSR, STS, CAPS and RAPD markers, was used for interval mapping of the QTLs controlling the stem length and internode number of pea. In the characterization of a given QTL, we(More)
The distinctness of, and overlap between, pea genotypes held in several Pisum germplasm collections has been used to determine their relatedness and to test previous ideas about the genetic diversity of Pisum. Our characterisation of genetic diversity among 4,538 Pisum accessions held in 7 European Genebanks has identified sources of novel genetic(More)
Quantitative trait loci for yield, yield components and seed protein content were investigated on the basis of experiments performed with two populations of pea (Pisum sativum L.) lines derived from linked crosses between lines Wt11238, Wt3557 and Wt10245 with contrasting characteristics. The yield-related traits were defined as components giving the grain(More)
Alkaloids represent the main antinutritional factor in lupins. The total content and qualitative composition of four major alkaloids in L. angustifolius L. were analyzed. The material included 329 accessions from the Polish collection divided into three classes of origin: wild lines, cultivars, and other man-made accessions. A very broad differentiation was(More)
