Cyanide levels were determined in leaves and roots using a modified picrate testing procedure [39]. The samples were rated for cyanide levels on a scale of 1 - 9. The score structure ranged from scale of 1 - 4 represent- ing 0 - 50 ppm, 5 - 6 representing 50 - 100 ppm and 7 - 9 representing over 100 ppm. The cassava accessions were ranked as low, medium and high cyanide content respec- tively.
