Abstract Data are presented concerning the action of N-nitroso-N-methylurea (NMU) and diethyl sulfate (DES) on barley during the cultivation of M/sub 1/ plants at an altitude of 2600 m and M/sub 2/ plants at altitudes of 2600 and 3860 m above sea level. The frequency of morphophysiological mutations in the treated variants was higher and the range of variability was wider under mid-altitude (2600 m) conditions than under high-altitude conditions (3860 m). The number of semi-sterile and sterile plants was higher when the mutagen-treated variants were cultivated at an altitude of 3800 m. A brief description is presented of certain mutants which are of interest from the point of view of selection and genetics. Such mutants include dwarf forms, with dense ears and with a rye-like ear, and having variegated and glossy leaves.
