Working procedures for cocoa germplasm evaluation and selection : Proceedings of the CFC/ICCO/IPGRI Project workshop, 1-6 February 1998, Montpellier, France |
| Popis: |
The objective is to describe methods for accurate evaluation of field resistance to Phytophthora pod rot in project trials. Firstly, the standard method for evaluation of incidence of Phytophthora in mature pods is described; this method is part of the procedure for yield assessment in project trials. Secondly, a method is described for complementary optional observations on Phytophthora attack on cherelles, immature pods as well as on ripe pods. Furthermore, suggestions are made for observations on Phytophthora stem canker incidence and on factors other than intrinsic resistance of the cocoa tree that may affect black pod incidence in the field. |
