The presence of fourth glume, ciliated lodicules, highly irregular meiotic divisions, the nature of inheritance of the character ‘oldness of spikelets’ and functioning of eggs with chromosome numbers other than 2n in crosses with S. spontaneum, distinguish atypical noble canes from S. officinarum 2n=80 forms. Based on the morphological and cytological resemblances of the two of the atypical noble canes to a synthetic interspecific hybrid S. officinarum (2n=80)×S. spontaneum (2n=80), it is suggested that the atypical noble canes are probably of hybrid origin.
