With the aim of making the point on feasibility and relative success of alien transfers into durum wheat via chromosome engineering, three transfer works, differing in origin and content of the alien introduction and in the transfer strategy adopted, are described. For the transfer of a powdery mildew resistance gene, Pm13, originating from Aegilops longissima and previously transferred to common wheat chromosome 3B, as well as for that of the leaf rust resistance gene Lr19 and its associated Yp (yellow pigment) gene, deriving from Ag. elongatum and introduced into 7A, the common wheat recombinants were employed as donors, from which the alien segments were homologously transferred into durum genotypes. On the other hand, for the transfer of common wheat chromosome 1D seed storage protein genes, phl mediated homoeologous recombination was repeatedly induced. This resulted in loss of individuals, including potentially desirable recombinants, probably due to imbalances created by thephl condition. However, recovered Gli-DllGlu-D3 tetraploid recombinants exhibited normal transmission and fertility. Preliminary evidence indicates a normal behaviour also for Glu-D1 '5 + 10' putative recombinants. Similarly, there was no negative impact from the transfer of the Pm13 gene, which has been successfully pyramided into Pm4a durum varieties. On the contrary, transfer of the Ag. elongatum segment showed normal female but almost no male transmission in one durum genotype. This in spite of the fact that the alien segment, proved to be, through in situ hybridization, considerably longer than previously believed, should contain an Sd-1 gene, causing preferential transmission in common wheat. While its behaviour is being checked in other durum genotypes, shortening of the alien segment, throughphl induced recombination, is also being carried out. Possible causes of the severe negative selection that this alien transfer seemingly encounters at the tetraploid level are discussed.

Wild relatives of common wheat, Triticum aestivum, and related species are an important source of disease and pest resistance and several useful traits have been transferred from these species to wheat. C-banding and in situ hybridization analyses are powerful cytological techniques allowing the detection of alien chromatin in wheat. Cbanding permits identification of the wheat and alien chromosomes involved in wheat-alien translocations, whereas genomic in situ hybridization analysis allows determination of their size and breakpoint positions. The present review summarizes the available data on wheat-alien transfers conferring resistance to diseases and pests. Ten of the 57 spontaneous and induced wheat-alien translocations were identified as whole arm translocations with the breakpoints within the centromeric regions. The majority of transfers (45) were identified as terminal translocations with distal alien segments translocated to wheat chromosome arms. Only two intercalary wheat-alien transloctions were identified, one induced by radiation treatment with a small segment of rye chromosome 6RL (H25) inserted into the long arm of wheat chromosome 4A, and the other probably induced by homoeologous recombination with a segment derived from the long arm of a group 7 Agropyron elongatum chromosome with Lrl9 inserted into the long arm of 7D. The presented information should be useful for further directed chromosome engineering aimed at producing superior germplasm.

“…The transmission of the translocation chromosomes through pollen was low and homozygous translocation lines were not recovered. Friebe et al (1987;1993) Putative recombinants between A-and D-genome chromosomes were selected using microsatellite (SSR) analysis. These markers show a much higher level of polymorphism in wheat as compared to other types of markers such as RFLPs, which show a very low level of polymorphism (Röder et al, 1998).…”

Aegilops tauschii Coss. (2n=14, DD) is a rich source of disease resistance genes for the improvement of cultivated wheat including several resistance genes against Hessian fly. To date, five Hessian fly resistance genes (H13, H22, H23, H24, and H26) have been transferred from Ae. tauschii to common wheat (Triticum aestivum L.). In this study, we attempted the transfer of four genes H22 (1D), H23 (6DS), H24 (3DL), and H26 (4D) from T. aestivum D genome onto A genome chromosomes of T. turgidum. The T. aestivum resistant parents WGRC01 (H22 on 1D), WGRC03 (H23 on 6DS), WGRC06 (H24 on 3DL), and WGRC26 (H26 on 4D) were crossed with T. turgidum cv. Langdon disomic substitution lines LDN 1D(1A), LDN 6D(6A), LDN 3D(3A), and LDN 4D(4A). We targeted the transfer of Hessian fly resistance genes into D-genome substitution chromosomes of T. turgidum by homologous recombination. In total 88 crosses were made. The resulting F 1 plants (345 seeds) were backcrossed with the LDN 5D(5B) substitution line in which chromosome 5B is absent and replaced by a pair of 5D chromosomes with the objective of transferring D genome Hessian fly resistance genes onto A or B genomes of T. turgidum by homoeologous recombination. A total of 2,053 segregating BC 1 F 1 plants were tested for Hessian fly resistance, and the resistant plants (1,132) were backcrossed again with LND 5D(5B) to produce BC 2 F 1 and selfed to produce BC 1 F 2 . In the BC 1 F 1 populations, 24 families segregated for an excess of resistant plants than the expected 1:1 resistant to susceptible plants suggesting that they were putative A-D genome positive recombinants. Mapping analysis using microsatellites was used in these families to identify recombinants between A-and D-genome chromosomes. The data indicated that H22 recombinants were recovered consisting of the distal part of the short arm of 1A, the proximal of 1DS, and the complete long arm of 1D. The recombinant can be described as T1AS-1DS1DL.Corresponding Author:-Moha Ferrahi.

Res. 5(11), 728-750 729The recombinant involving H23 probably consisted of the whole short arm of 6D and the long arm of 6A, and is described as T6DS6AL. The centromeric marker indicated that this recombinant has the centromere from chromosome 6A. In addition, monosomic substitution lines were recovered for the remaining resistance genes H24 and H26. These monosomic substitution lines are useful germplasm for further manipulation aimed at transferring genes H24 and H26 to durum wheat.Copy Right, IJAR, 2017,.
