AbstractStatistical comparisons of samples of chironja, orange and grapefruit were made of the characters of the leaves, flowers, fruits, and juice. The comparisons demonstrated that these fruits differ with regard to the above-mentioned characters when the latter are combined to provide certain quality indices. The four types of indices discriminated at the 1-percent level of statistical significance when comparing 100-fruit samples of each of the three fruits with each other. It is suggested that in identifying a single fruit in accordance with the described procedure, the characteristic index based on fruit characters be used first. However, if the result of this test is not conclusive, the addition of the characteristic index based on juice characters will aid in the identification of a single fruit with a high degree of accuracy.
