Pendugaan Daya Gabung dan Nilai Heterosis Hasil Persilangan Half Diallel Cabai Rawit (Capsicum annuum L.).

Abstract

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 (RCBD) 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 C10 x IPB C174, IPB C160 x IPB C291, IPB C174 x IPB C291, dan IPB C291 x IPB C293 had positive SCA, heterosis, and heterobeltiosis values for some variable observed. Genotype IPB C10 x IPB C174 dan IPB C160 x IPB C291 had higher yield for each plant than the commercial varieties which were Sonar and Nirmala
