Abstract
The primary goal for most breeding programs in crops is to select genotypes with high yield, resistant to pests and diseases and other desirable agronomic traits while preserving genetic diversity. This paper aimed to estimate component of genetic variation and heritability for specific traits of the cocoa progeny trial in Malaysia. It is very important to understand the inheritance pattern of some traits in generated progenies for breeding strategies especially in the development of superior planting materials. The experiment was laid out in a randomized complete block design of three replications in a progeny trial plot at CRDC Bagan Datuk, Perak. The collected data were subjected to analysis of variance (ANOVA). For this study, the results apply to specific population and environment. This finding would assist cacao breeders to understand the genetics controlling specific traits especially yield and VSD disease tolerance in cacao planting material.
