Abstract
Aluminum tolerance of two sets of hexaploid triticale (x Triticosecale Wittmack) lines with disomic substitutions of the D-genome chromosomes from Triticum aestivum L. was analyzed by the modified-pulse method. Of the 20 substitution lines in winter triticale Presto, and 18 lines of spring triticale Rhino, six and nine lines, respectively, showed improved tolerance relative to that observed in the control lines. The D-genome chromosomes in substitutions 1D(1B), 3D(3A), 3D(3B), 4D(4A), 4D(4B) and 6D(6B) significantly ( p <0.01) improved Al tolerance in both sets of lines. High percentages of tolerant plants were also observed in 2D(2B) and 5D(5A) substitutions in Presto and in 2D(2A), 2D(2B), 5D(5B), 6D(6A) and 7D(7A) substitution lines of Rhino. In no instance, the removal of individual rye chromosomes, by substitutions, improved Al tolerance of the recipient line. Moreover, the presence of a complete rye genome, and especially of chromosome 3R, was necessary for triticale's tolerance to aluminum. The results also indicated some effects of allelic variation present on both rye and wheat chromosomes, and a possibility of interactions of various factors
