A miniature phenotype found in peanut( Arachis hypogaea L. ‘Tennesse Red’), which has significantly reduced vegetative and reproductive characteristics, was investigated to determine the mode of inheritance. Three distinct classes resulted from selfing the miniature class: micro, a form with extreme reduction in stems and leaves; miniature (mini), plants with general reduction in all organs; and normal. The F 1 and F 2 data from a complete diallel crossing study indicated monogenic inheritance with partial dominance for micro phenotype. The gene symbol Mi is proposed for the allele involved in the expression of the micro and mini plants.
