Abstract: This study covers two Bulgarian crosses between high-yield varieties sesame Milena and Sadovo 1 to shattering capsules and promising line non-shattering capsules Sadovo 3959. Used incomplete dialel crosses. Measured are 10 morphological traits, the mode of inheritance their heterosis effect inheritance in a broad sense, inheritance in the strict sense and the presence of additive-dominant model. Variety Sadovo 1 used as a maternal form transmitted high-dominant elements yield high heterosis effect in such cases and missing reciprocal action confirmed additive-dominant model. Milena variety also transmits these dominant elements. Signs responsible for suitable for mechanized harvesting of the plant architecture in Sadovo 3959 are inherited dominantly.
