Genetic analysis of yield attributes in Cocoa (Theobroma cacao L.)

Abstract

Genetic analysis of yield attributes in cocoa (Theobroma cacao L.) was undertaken in the Department of Agricultural Botany, College of Horticulture, Vellanikkara, Trichur during 1992-93, with an objective to assess the extent of variability present in the population and to get an insight into the genetic behaviour and mode of inheritance of yield and the different yield attributes in cocoa. A total of 244 steady bearing trees consisting of 19 hybrids and 15 parents were taken for the study. Observations were recorded on 16 characters including yield and yield attributes. Statistical analysis of the data led to the following conclusions. Variability in most of the characters followed the same trend in both the hybrid and the parent populations.
