Abstract
A half diallel set (forty five Fi crosses) including ten parental lines of chilli {Capsicum annuum L.) were grown in a randomized block design with three replications under two environments, kharif as well as rabi season at Vegetable Research Farm, Gujarat Agricultural University, Anand Campus, Anand during 1998-99. The main objective was to study heterosis, combining ability and genetic components following Griffing and Hayman's approach for yield and its components. Analysis of variance for individual environment as well as pooled over environments revealed presence of considerable amount of variability among the genotypes (parents and hybrids) for all the thirteen characters studied. The pooled analysis revealed the presence of high amount of genotype X environment interactions for days to flowering, primary branches per plant, fruits per plant, fruit length, fruit shape index, fruit weight, green fruit yield per plant, days to maturity, total chlorophyll and total capsaicin content. The hybrid, RHRC-16-5 X Guchhedar, BC-14-2 X SG-5 and ACS-92-3 X Guchhedar exhibited maximum heterobeltiosis for green fruit yield per plant on pooled basis.
