A diallel set of crosses among nine popcorn (Zea mays) cultivars, UNB-2, RS-20, UEM-J1, UEM-M2, CMS 42, CMS 43, Vicosa, Beija-flor and advanced generation of hybrid three-way Zelia, and their hybrid combinations was carried out to obtain heritability and heterosis estimates. The cultivars and F1s were evaluated in two crop years (1998/99 and 1999/2000) with three replications each year in Iguatemi, State of Parana, Brazil. The results allowed the synthesis of composts based on cultivars of high combining ability for yield such as UNB-2 and CMS-42 and the cultivars Zelia, RS-20 and UEM-M2 to popping expansion. The cultivars Beija-flor and RS-20 were recommend to be used in a reciprocal recurrent selection programme. For popping expansion there are positive and negative heterosis, indicating non-unidirectional dominance..
