Indonesia is one of leading cocoa producing and exporting country. The increase of production has not been in concomitant with quality improvement. One of several factors determines the quality is its fat content. Improvement of planting material through breeding, yield increase, and better quality should be considered simultaneously. Three days old germinated cocoa seedlings derived from six varieties were irradiated with gamma rays at 0.5, 1.0, 1.5, and an untreated as treatments. Thirty irradiated seeds for each treatment combination were planted at polybag, arranged in completely randomized design for three months to observe their survival. Five surviving seedlings of each treatment combination were planted in field on April 1995 In mid-1998 several mutant bushes started bearing pods. Data on number of bean per pod, bean weight, shell content, and butterfat content were examined from the available harvested pods. The results indicated that higher dose of irradiation tend to decrease the surviving mutants. Statistically, no differences were observed on the number of bean per pod and the bean weight even though their coefficient of variability was considered high. The shell and butterfat content of some mutant bushes were significantly different with their mother bushes
