Investigations have centered on 69 intermedium mutants, representing 9 loci, in double mutant combinations, in double combinations with the six-row gene hex-v, in triple combinations with hex-v, and in triple and quadruple mutant combinations. The effects of the interaction may differ among the three characters of lateral floret development, among intermedium loci, and among alleles of the particular locus. Particular types of gene interaction are indicated, particular loci being more competent than others and the particular alleles being more competent in relation to the constelation of loci
