Abstract
The detection of intervarietal variation in C-banding pattern of meiotic 1B, 4B and 5B chromosomes in F1 hybrids of common wheat, Triticum aestivum L., permitted the analysis of interchromosomal affinity on the separation of their centromeres to opposite poles at first metaphase.
Testing meiotic configurations for centromere co-orientation, non-randomness was found, resulting from an excess of the type of distribution with the three chromosomes having the highest amount of heterochromatin going to the same pole. The centromeres that congregated predominantly together at the same pole were not derived from the same parent of the hybrids. Consequently, the predominance of that type of separation cannot be attributed to centromeric affinity.
