Abstract

This paper presents a detailed comparison of meiotic chromosome behavior in sterile hybrids and in their relatively fertile, colchicine-induced amphidiploids. An analysis of the hybrid Agropyron trichophorum × Triticum is reported for the first time.

Results indicate that two factors are involved in these interspecific crosses: genic suppression of chromosome pairing in the hybrid and its amphidiploid; and disharmonious interaction of genes controlling the same cell processes in Triticum and Agropyron, resulting in failure of complete amphidiploid meiotic pairing.
