Chromosoma Aims and scope Submit manuscript

Summary

  1. 1.

    Chromosome-deficient cells were found at the meiotic stage in synthetic amphiploids derived from various diploid-tetraploid combinations in the Avenae.

  2. 2.

    Chromosome-deficient cells were found to be dependent on the species used as parents to produce the triploid F1 hybrid.

  3. 3.

    Chromosome deficiency in two amphiploid plants Cc 4387/1 and Cc 4435/1 did not follow a Poisson distribution.

  4. 4.

    A study of chromosome pairing revealed that aberrant cells undergo normal meiosis.

  5. 5.

    First (A1) and second (A2) generation amphiploid plants showed that chromosome-deficient gametes were functional.

  6. 6.

    The occurrence of chromosome-deficient cells is attributed to spindle abnormalities at the pre-meiotic divisions.
