TL;DR: Out of five F1 plants of the crossSorghum controversum (2n=40)×S.almum one was found to be desynaptic and it is suggested that this desynapsis, which is of the “medium-strong” class, may be due to a spontaneous mutation.
Abstract: Out of five F1 plants of the crossSorghum controversum (2n=40)×S.almum (2n=40) one was found to be desynaptic. It is suggested that this desynapsis, which is of the “medium-strong” class, may be due to a spontaneous mutation. Several meiotic abnormalities have been recorded and possible explanations are suggested. The plant was found to be highly pollen sterile and did not set seed on selfing. However, when pollinated with normal pollen from one of its parents, 1 to 5 seeds per panicle were obtained. The possible utility of this material for physiological studies on crossing over and chiasma formation has been indicated.
