The aim of this research was to study estimation general combining ability (GCA) and specific combining ability(SCA) of six bird pepper inbred lines (Capsicum annuum L.), heterosis and heterobeltiosis of fifteen bird pepper hybrids in half diallel crosses. The experiment were conducted from November 2013 to April 2014 using a Randomized Complete Block Design with three replications at Leuwikopo University Farm, IPB. Analysis of GCA and SCA were based on the Griffing’s model of diallel design method II. Heterosis values were predicted based on the average values of their parents and heterobeltiosis were predicted based on the average values of the highest parents. Genotype IPB C174 had the highest GCA for fruit weight, fruit length, fruit width, and yield for each plant. Hybrid IPB C160 x IPB C291 and IPB C291 x IPB C293 had positive SCA, heterosis, and heterobeltiosis values for some variable observed. Hybrid IPB C174 x IPB C291 had better advantages than the commercial varieties which were Santika, Bhaskara, Sonar, and Nirmala on fruit weight characters.Keywords: bird pepper, combining ability, half diallel, heterosis
