In order to construct an RFLP map of barley, two populations were analyzed using 251 genomic and cDNA markers: one population comprised 71 F1 antherderived double haploid (DH) individuals of an intraspecific cross (IGRI x FRANKA), and the other 135 individuals of an interspecific F2/F3 progeny (VADA x H. spontaneum). The distribution of nonrepetitive clones(More)
This paper reports on the first advanced backcross-QTL (quantitative trait locus) project which utilizes spring barley as a model. A BC2F2 population was derived from the initial cross Apex (Hordeum vulgare ssp. vulgare, hereafter abbreviated with Hv) × ISR101-23 (H. v. ssp. spontaneum, hereafter abbreviated with Hsp). Altogether 136 BC2F2 individuals were(More)
In the present paper, we report on the selection of two sets of candidate introgression lines (pre-ILs) in spring barley. Two BC2DH populations, S42 and T42, were generated by introgressing an accession of Hordeum vulgare ssp. spontaneum (ISR42-8, from Israel) into two different spring barley cultivars, Scarlett (S) and Thuringia (T). From these BC2DH(More)
The objective of the present study was to identify favourable exotic Quantitative Trait Locus (QTL) alleles for the improvement of agronomic traits in the BC2DH population S42 derived from a cross between the spring barley cultivar Scarlett and the wild barley accession ISR42-8 (Hordeum vulgare ssp. spontaneum). QTLs were detected as a marker main effect(More)
By searching the EMBL DNA sequence database, we were able to develop 39 new, database-derived barley microsatellites. Eighteen of these EMBL microsatellites were mapped either to the interspecific barley map Lerche×BGRC41936 (L×41), the Igri×Franka map (I×F, Graner et al. 1991), or to both maps simultaneously. In addition, all 39 EMBL microsatellites were(More)
We have established a first linkage map for beets based on RFLP, isozyme and morphological markers. The population studied consisted of 96 F2 individuals derived from an intraspecific cross. As was expected for outbreeding species, a relatively high degree of polymorphism was found within sugar beet; 47% of the DNA markers were polymorphic for the chosen(More)
The advanced backcross QTL (AB-QTL) strategy was utilised to locate quantitative trait loci (QTLs) for baking quality traits in two BC2F3 populations of winter wheat. The backcrosses are derived from two German winter wheat cultivars, Batis and Zentos, and two synthetic, hexaploid wheat accessions, Syn022 and Syn086. The synthetics originate from(More)
Forty-one accessions of the genusBeta representing wild and cultivated species of all sections were analyzed by DNA “fingerprinting”. Four sugar beet minisatellite DNA probes revealed characteristic banding patterns with Southern-hybridizedBeta DNA restricted withHindIII. A total of 111 polymorphic RFLP bands were scored across all accessions. Cluster(More)
This paper reports on the first comparative advanced backcross quantitative trait locus (AB-QTL) study in barley. The BC2F2 population H×101 was generated from crossing var. Harry [H; Hordeum vulgare ssp. vulgare (Hv)] with ISR101-23 [101; H. v. ssp. spontaneum (Hsp)]. The results of the AB-QTL analysis for 13 quantitative traits are presented and,(More)
The control of flowering time has important impacts on crop yield. The variation in response to day length (photoperiod) and low temperature (vernalization) has been selected in barley to provide adaptation to different environments and farming practices. As a further step towards unraveling the genetic mechanisms underlying flowering time control in(More)
