Using DUS characters five composite varieties of maize (Super -1 composite, Composite-6, Composite-8, Composite-14 and Composite-15) were characterised through morphological features of the plant and the seed utilising fifteen descriptive characters. The identification keys based on plant and seed morphology were prepared. All the varieties could be distinguished on the basis of morphological features of the plant, only three could be identified on the basis of seed characteristics. The keys could be used to define parameters of certification and allow for determining similarities and differences in DUS (Distinctness, uniformity and Stability) testing. | DUS characterisation of corn Zea mays L. cultivars
