【摘要】 本试验由25名来自中日两国的品尝员，对7种中国产粳稻品种进行了食味品尝评价，并以此试验结果为基础，以每个品尝员的综合评价与全体品尝员的综合评价的相关系数作为嗜好性；以判定每个品尝员的评价结果的品种间差异是否显著的方差分析的F值作为识别能力，来对评价结果进行筛选。嗜好性和识别能力之间相关系数为0.347，且不显著。筛选后中国品尝员的复回归系数由0.862上升至0.925，决定系数由0.743上升至0.856。更多还原

【Abstract】 In this experiment, 25 Chinese japonica rice varieties were evaluated by a panel of 25 tasters from China and Japan. Based on the results of this experiment, the preference of each taster was determined by using the correlation coefficient between the comprehensive evaluation of each taster and the overall assessment of all tasters. The ability to discern differences among the rice varieties was assessed by using the F-value from the ANOVA to determine whether the variances between varieties were significant. The reevaluated results showed an insignificant correlation of 0.347 between preference and discrimination ability. After the screening, the Chinese taster’s complex regression coefficient rose from 0.862 to 0.925, and the coefficient of determination increased from 0.743 to 0.856.更多还原
