C-banding patterns of Hordeum chilense and of Triticum aestivum 'Chinese Spring' - H. chilense disomic addition lines were analyzed and compared with in situ hybridization patterns using a biotin-labeled highly repetitive Triticum tauschii DNA sequence, pAs1, and a wheat 18S-26S rDNA probe. All seven H. chilense chromosomes pairs and the added H. chilense(More)
A segregating progeny set of 96 F1 diploid hybrids (2n=2x=14) between “Blush Noisette” (D10), one of the first seedlings from the original “Champneys’ Pink Cluster”, and Rosa wichurana (E15), was used to construct a genetic linkage map of the rose genome following a “pseudo-testcross” mapping strategy. A total of 133 markers (130 RAPD, one morphological and(More)
The construction of a physical map of chromosome 4Hch from Hordeum chilense containing molecular markers capable of detecting segments of this chromosome in a wheat background would be very useful for marker-assisted introgression of 4Hch chromatin into both durum and common wheat. With this aim, the applicability of 106 barley chromosome 4H primers (62(More)
Alloploidy, one of the most efficient evolutionary mechanisms in nature, has not been extensively exploited in plant breeding programmes. Many genomic combinations remain to be created by plant breeders, to be used directly as new crops or indirectly to widen the genetic basis of crops. The Triticeae tribe, to which wheat belongs, is among the botanical(More)
Hordeum chilense Roem. et Schult. is a diploid wild South American barley that contains genes of interest for cereal breeding, many of them located on chromosome 1Hch. In the current study, two H. chilense-wheat addition lines with deletions in the 1Hch chromosome were used for sub-arm localization of five prolamin (glutenin and gliadin) loci and 33 EST-SSR(More)
Crested wheatgrass (Agropyron cristatum L. Gaertn.) is a perennial species of economic importance as forage that also displays potentially valuable traits for wheat improvement trough intergeneric hybridization. In order to incorporate resistance genes from A. cristatum against wheat leaf rust (Puccinia triticina Erikss.) into common wheat (Triticum(More)
Structural changes in Hordeum chilense chromosome 3Hch were obtained in common wheat background by crossing tritordeum (the fertile amphiploid H. chilense–T. turgidum, 2n = 6x = 42, AABBHchHch) with the disomic addition line of chromosome 2Cc from Aegilops cylindrica in common wheat cv. ‘Chinese Spring’ (CS). Hybrid plants (2n = 43, AABBDHch + 2Cc)(More)
Agropyron cristatum exhibits resistance to Blumeria graminis f. sp. tritici. Disomic and ditelosomic chromosome addition lines of A. cristatum in ‘Chinese Spring’ wheat were utilized to determine which A. cristatum chromosomes carry resistance gene(s). Resistance is conferred by gene(s) on chromosome arms 2PL and 6PL. The availability of molecular markers(More)
Agropyron (Gaertn) is a genus of Triticeae which includes the crested wheatgrass complex, i.e. A. cristatum (L.) as representative species containing the P genome. This species is an important source for increase the genetic variability of both durum and bread wheat. Among the possible interesting features to be introgressed into wheat are resistance to(More)
Intergenomic translocations between wheat, Hordeum chilense and Hordeum vulgare have been obtained in tritordeum background. Advanced lines from the crosses between three disomic chromosome addition lines for chromosome 2Hv, 3Hv, and 4Hv of barley (Hordeum vulgare) in Triticum aestivum cv. Chinese Spring (CS) and hexaploid tritordeum (2n = 6x = 42,(More)
