    The article presents the variability in mutant generations of amaranth seed (Amaranthus hópochonacdrius L.) using different doses of gamma radiation. The negative effect of gamma irradiation on amaranth field germination plants of M1 was proved, which decreased with an increase in the mutagen dose (on average, it was 58-50% in the control variant, 49-55, and 2-3% respectively). Plants M1, which grew from seeds treated with mutagen, were characterized by moderate and significant depression of growth processes (a decrease in plant height and panicle length by an average of 10-15 cm compared to the control). Doses of gamma radiation of 400 and 700 Gy induced chlorophyll changes (Albina type), which led to a complete disruption of chlorophyll synthesis in plants. Gamma irradiation has been established to be one of the powerful factors that can significantly change the characteristi.. View More»
