Abstract
Cytological selection within the F2 to F6 generations from the cross between the amphiploids T. durum - Aegilops squarrosa (AABBDD) and T. durum - Agropyron elongatum (AABBEE) yielded 33 hexaploids having the A and B genomes of durum wheat and a third genome comprised of various combinations of Aegilops and Agropyron chromosomes. Cytological examination of backcross F1 plants revealed that several new genomes ranging in composition from 4D + 3E chromosomes to 2D + 5E chromosomes had been produced. The derived hexaploids were similar to the parents in fertility and meiotic stability.This publication has 2 references indexed in Scilit:
