2] hybrids, the deviation of the heterozygous dominance effect for a CS-B line and a cultivar from the heterozygous dominance for TM-1 line and the same cultivar can be considered as due to the allelic interactions between the substituted chromosome or the chromosome arm from 3-79 in the CS-B line and the homologous chromosome or arm in the respective cultivar.
