Stanislav Stamatov, Manol Deshev

Abstract: This study involved crosses between high-yielding varieties of three Bulgarian peanuts and an advanced breeding line with four introduced materials from the USA. Five morphological attributes, mode of inheritance, heterosis effect and the presence of additive-dominant model have been measured. Stanko variety used as a mother form transmitted maternal over dominantly elements of production of
fruits and seeds with high heterosis effect and in these cases there is no interaction between genes. Variety Tsvetelina also transmit these dominant elements.
