Title: The Introgression of Genetic Information from <i>Triticum monococcum</i> L. into Hexaploid Triticale by Hybridization with a <i>T. monococcum</i>×<i>S. cereale</i> Amphiploid
Abstract: Abstract From the crosses (6 × triticale ‘Lasko’× AARR) בLasko’ one plant with 56 chromosomes was obtained. The selfed progenies showed reduction of somatic chromosome number. A reciprocal cross of hyperploid introgressive plants with ‘Lasko’ indicated similar transmission rates of additional chromosomes through female and male gametes. The degree of initial reduction is of great importance for the number of succeeding generations needed to reach the hexaploid level. With regard to the output of introgressive lines of practical breeding importance, it is necessary to continue and to promote the recombination processes between donor and recipient genetic information for as long as possible. An interruption of recombination by beginning selection too early leads to the loss of genetic variability in the progenies.
