Compatibililty and duration of pod maturation in Guianan wild cocoa trees - Preliminary results

Lachenaud P., Oliver G.. 2005. Ingenic newsletter (10) : p. 20-22.

Compatibility and duration of pod maturation are among the traits studied at CIRAD's Paracou-Combi station (Sinnamary, French Guiana) on Guianan wild cocoa trees. These two descriptors belong to the "secondary agronomic" category, since they appear to affect, in an as yet poorly documented way, net yields: the first insofar as self-compatibility is sometimes considered to be an advantage (nothing more, except in monoclonal plantations), and the second is involved in disease escape phenomena. We report here on the preliminary results obtained in an initial phase of research. (Résumé d'auteur)
