Abstract
In a study of the morphology and pairing behaviour of the chromosomes of a tetraploid race of S. arundinaceum, the ten basic types characteristic of the diploid grain sorghums were recognized. In a total of 131 pachytene associations studied, the frequency of exchanges varied from none to two in a given set of four pairing chromosomes. The exchanges were distributed along the length of the chromosomes. The results indicated an autoploid origin for the tetraploid.
