Popis: A study was conducted to determine whether hollow heart potatoes might be separated from normal ones by a nondestructive method based on an objective criterion. The profile of x-ray density measured along the longitudinal axis of each of 106 tubers was recorded and then analyzed by computer. The second derivative of the x-ray density profile provided a basis for detecting hollow heart. All of the defective tubers were separated without inclusion of any normal tubers. The incidence of hollow heart was 21.4%.
