Abstract

An experiment was performed to reveal the organogenetic capacity of some mutant lines ofArabidopsis thaliana (L.) Heynh. and their hybrids. The mutant lines have lower shoot- and root-forming capacity than the normal line, but their hybrids recovered the capacity to the level of the normal parent line, and in some cases they showed hybrid vigor. Leaf segments showed both the shoot- and root-forming capacity in the normal line and in hybrids. Stem segments showed high shoot-forming and low root-forming capacity in all the lines and hybrids. Calluses showed root-forming capacity but scarcely formed shoots in both the parent lines and hybrids.
