Plant phenotype measurements for large numbers of samples are typically labor-intensive and challenging, especially for traits that require destructive measurements. To improve the efficiency of phenotypic measurement, we evaluated the accuracy of nondestruct ive measu rement of i nd iv idua l lea f a rea ( L A ) a nd st em leng t h (SL) of tomato segregating lines, derived from a cross between Japanese and Dutch F1 varieties, using a Kinect game console as a 3-D sensor in this study. Two types of software were used for nondestructive measurements using the sensor: one for measuring LA and another for measuring SL. The values obtained were compared with the actual values obtained using destructive measurement. The results showed that the correlation coefficients between the SL values obtained using destructive and nondestructive measurements (kPH) ranged from 0.95 to 0.99, indicating a very high accuracy throughout the 91-day cultivation peri-
