MOLECULAR FINGERPRINTING OF COCOA CLONES
Project Leader : Dr. Rosmin Kasran
Molecular markers linked to a trait of interest provide an opportunity to carry out breeding more efficiently and allows plants to be screened for adult traits at the seedling stage. A collection of molecular and agronomic markers distributed throughout the genome and at known genetic distance from one another is a genetic linkage map.
A genetic linkage map incorporating molecular and agronomic traits allows a trait to be monitored just by observing a closely-linked molecular marker. The trait does not have to be expressed. Thus seedlings that will mature into trees with superior adult traits, such as high yield, and black pod resistance can be selected.
For high density planting, dwarf materials offer cocoa growers the opportunity of obtaining greater yield per unit area and high early productivity. It also reduces labor costs for pruning and harvesting. The smaller canopies improve pesticide spray penetration & light distribution. Therefore, higher fruit quality may result from high density dwarf trees.
A classification of cocoa clones into dwarf and vigorous types using molecular markers was developed.
