Genetic studies of yield components and pungency in chilli (Capsicum annuum L.) genotypes through Hayman’s approach

Abstract

Estimation of genetic parameters using the Hayman approach diallel method was developed in a population formed close to the Hardy-Wienberg equilibrium. The genetic parameter information obtained can be used as the basis for chilli breeding activities, especially for capsaicin content and high productivity. The aim of this study was to obtain information on genetic parameters and gene action that control the capsaicin content and productivity components in chilli using the Hayman approach diallel analysis method. The results showed that all observed characters were controlled by the additive genes action except for the character number of days taken for flowering as indicated by the comparative value of narrow-sense heritability and broad-sense heritability. The distribution of genes in the parents of all observed characters was uneven and all characters were controlled by 1-3 genes. This information is useful for determining the direction of the variety that will be produced in future breeding activity.
