To prove the two-nuclear migration from the diploid inoculum into the large haploid mycelium in the diploidisation by the compatible diploid mycelium, the experiment was performed, using Coprinus macrorhizus f. microsporus.
The legitimate combinations, e.g. AB''(A'B+Ab) in which the nuclei AB' and A'B derived from the same fruit-body and the nucleus Ab derived from a different one, were made. In some of these combinations, the nucleus Ab advanced more rapidly than A'B; and, when the nucleus A'B arrived late at the terminal cell of the haplont AB', conjugation occurred between the nuclei Ab and A'B.
The above results may be explicable from the assumption that the speed of nuclear migration and the conjugation affinity between two compatible nuclei are controlled by the modifiers.
