Cote d'Ivoire - CIRAD/IDEFOR Datafile: CIV___DS CIV - CIRAD/IDEFOR Clone trial Germplasm: 67 clones were compared in five clonal trials. IFC 5 was used as a control in each of the trials.

Analysis carried out on the following number of harvests: D11/2 - 1979/80 to 1981/92 3 harvests D13/4 - 1977/78 to 1981/82 5 harvests G8 - 1978/79 to 1981/82 4 harvests A18/2 - 1987/88 to 1991/92 5 harvests Sensitivity to pod rot was calculated as the ratio of rotten pods to healthy pods. Sensitivity to mirids was calculated on a scale of 0 to 4 according to the amount of die back caused by mirid damage since the year of planting.

Cote d'Ivoire - IDEFOR/CIRAD Datafile: MIR___DS CIV - IDEFOR/CIRAD Mirid index Germplasm: c.40 clones Environment: Old clonal trials, from 33 to 45 trees per clone. Method: Cumulative damage due to mirids estimated in old clonal trial. A score from 0 (no attack) to 4 (severe attack) was given to individual trees and the results analysed for three trials.
