Abstract
Chromosome pairing and meiosis were studied in cross-fertile and cross-sterile sorghum lines and F1 hybrids between one cross-sterile and several fertile lines. The cross-fertile parents exhibited regular meiosis, but the cross-sterile ones and the hybrids had abnomalities indicative of non-homologies, deficiencies and/or duplications. The significance of the chromosomal differentiation in cross-sterile sorghums in relation to the origin of cross-sterility and apomixis was discussed.
