We have compared the effect of UV-laser composite mutagenesis and UV mutagenesis on abscisic acid(ABA)- producing strains. The result showed that the positive mutant rate and the increase ratio of productivity were higher in UV-laser group than in UV group .A high yield and stable strain was obtained after UV-laser treatment. Its productivity was over 2.1 mg·g -1 during five generations and 32% higher than that of the original strain.
