Characterisation of morphology and anatomy of the main cocoa varieties in the Southern Vietnam

This study was done to enhance the morphology and anatomy data of twenty cocoa cultivars (Theobroma cacao L.) which widely grow in the Southern Vietnam. Reproductive organs and plant organs were analyzed and compared based on both the morphological characteristics and anatomical tissue. These cocoa clones analysis refered from established procedures. Two groups of hybrid comprised Criollo characteristic and Forastero features. The Forastero hybrid group included TD 5, TD 6, TD 7, TD 9, TD 11, TD 13, CT 5, CT 6 and CT 21 with Amelonado pod set and yellow/orange yellow peel. The Criollo hybrid showed Criollo characteristics with Cundeamore/Angoleta pod set (CT 7, CT 8, CT 9, TD 1, TD 2, TD 8, TD 12, TD 14,TD 3, TD 6, TD 10) and red/orange red peel (TD 3, TD 6, TD 10). The tissue anatomy and floral description were not differ among samples. This work showed significant results for further biomolecular researches and contributed to breeding programs, conservation and variety selection activities.
