Evaluasi Daya Gabung Hibrida Hasil Persilangan Half Dialel Lima Genotipe Cabai (Capsicum annuum L.) di Lahan Gambut

Abstract

The objective of this study is to determine the value of general combining ability, and specific combining ability
hybrids of parental crosses by half-dialel scheme on the peat land. The experiment was carried out on the peatland
Rimbo Panjang Faculty of Agriculture Riau University.The genotypes consisting of 15 crosses from IPB half dialel
crosses chili in three replicates. To analyze general combining ability (GCA) or specific combining ability (SCA)
influence of the variable, analysis of variance for diallel cross according to Griffing’s method 2 was used. The result
shows, the highest value of general combining ability of stem diameter, fruit diameter, fruit weight and total weight per
fruit were obtained from genotype C5. Genotype C159 has high value of general combining ability of plant height, stem
dichotomous and crown width, and Genotype C 120 has high value of general combining ability of length fruit.
Meanwhile the highest specific combining ability based on yield component is genotype C5xC120
