      Aegilops introgressions as dependent on the genome composition].
PG  - 516-26
AB  - Introgressive hybridization is an efficient means to improve the genetic 
      diversity of cultivated cereals, including triticale. To identify the triticale 
      lines with Aegilops introgressions, genotyping was carried out with ten lines 
      obtained by crossing hexaploid triticale with genome-substitution forms of the 
      common wheat cultivar Avrora: Avrolata (AABBUU), Avrodes (AABBSS), and Avrotika 
      (AABBTT). The genome composition of the triticale lines was studied by in situ 
      hybridization, and recombination events involving Aegilops and/or common wheat 
      chromosomes were assumed for nine out of the ten lines. Translocations involving 
      rye chromosomes were not observed. Substitutions for rye chromosomes were 
      detected in two lines resulting from crosses with Avrolata. Genomic in situ 
      hybridization (GISH) with Ae. umbellulata DNA and molecular genetic analysis 
      showed that chromosome 1R was substituted with Ae. umbellulata chromosome 1U in 
      one of the lines and that 2R(2U) substitution took place in the other line. 
      Fluorescence in situ hybridization (FISH) with the Spelt 1 and pSc119.2 probes 
      revealed a translocation from Ae. speltoides to the long arm of chromosome 1B in 
      one of the two lines resulting from crosses with Avrodes and a translocation in 
      the long arm of chromosome 7B in the other line. In addition, the pSc119.2 probe 
      revealed chromosome 1B rearrangements in four lines resulting from crosses with 
      Avrolata and in a line resulting from crosses with Avrotika. The lines were 
      tested for main productivity parameters. A negative effect on all productivity 
      parameters was demonstrated for Ae. umbellulata chromosome 2U. The overwinter 
      survival in all of the lines was similar to or even higher than in the original 
      triticale cultivars. A substantial increase in winter resistance as compared with 
      the parental cultivar was observed for the line carrying the T7BS-7SL 
      translocation. The line with the 1R(1U) chromosome substitution seemed promising 
      for the baking properties of triticale.
