Abstract

The accuracy of the results of a sensory test for highly palatable rice cultivars comparable to Koshihikari by a small panel was evaluated statistically by analysis of variance. Concerning the overall eating quality, differences among cultivars and panel members were significant. However, the interaction between cultivars and panel members was not significant, showing that the evaluation of cultivars by panel members as a whole is meaningful. The taste preference of the panel members with a reputation for high tasting ability generally coincided with the mean value of the palatability of all panel members. The number of panel members who had high differentiating ability for overall eating quality was 5 out of 17 members (30%), and the least significant difference (LSD (0.05)) for cultivar difference in overall eating quality was 0.27. Thus, it was concluded that the sensory test for highly palatable rice cultivars by a small panel is reasonable. The reliability of the panel as a whole seems to be more important than that of each panel member singly in the sensory test for highly palatable rice cultivars comparable to Koshihikari.
