Chiasma frequencies and chiasma distribution in di ploid tetra ploid auto allo poly ploid and synthetic amphi di ploid wheats



Chiasma frequencies and chiasma distribution in di ploid tetra ploid auto allo poly ploid and synthetic amphi di ploid wheats



Biologisches Zentralblatt 101(3): 385-393



Chiasma distribution between and within bivalents was investigated in diploid, tetraploid, auto-allopolyploid and synthetic amphidiploid wheats. One chromosome-arm may form either 1 terminal + 1 proximal, 1 interstitial, 1 terminal or no chiasma. Significant deviations of the frequencies observed from the expected one in 2-armed chromosomes by chance recombination demonstrate interference between chiasmata across the centromere, disturbance of interference in synthetic lines, species- and chromosome-specific patterns, and disturbance of chromosome pairing. Auto-allopolyploids form multivalents.
