The objective of this research was to study heterosis and heterobeltiosis effects of fi fteen chili genotypes (Capsicum annuum L.), the general combining ability (GCA) and specifi c combining ability (SCA) of six chili inbred lines through half diallel crosses. The experiment was conducted from November 2008 to June 2009 using a Randomized Complete Block Design with three replications at IPB experimental fi eld, Leuwikopo, Darmaga. Heterosis values were predicted based on the average values of their parents whereas heterobeltiosis were predicted based on the average values of the highest parents. Analyses GCA and SCA were based on the Griffi ng’s fixed model of diallel design method II. Genotype IPB C2 had the highest GCA for fruit weight and fruit length. Genotype IPB C15 had the highest GCA for yield per plant and percentage of marketable fruit. Hybrid IPB C2 x IPB C14 and IPB C9 x IPB C14 had the highest heterosis, heterobeltiosis, and SCA for all fruit characters and yield per plant.
