Soybean [Glycine max (L.) Merrill] seeds from the backcross ‘Harosoy3’ ✕ T245 were analvzed for electrophoretic banding pattern of SBTI-A2. Harosoy produced a fast-moving band at Rf 0.79 and T245 produced a slowmoving band at Rf 0.75. All seeds having either fast or slow bands bred true in the next generation. Seeds having both fast and slow bands produced progenies in a ratio of 26 fast:50 fast and slow:24 slow. Our evidence confirmed that a single locus with two codominant alleles, which we designate as Ti1 and Ti3, controls the two protein forms.
