Abstract: In order to accelerate the process of potato germplasm improvement and variety breeding, 18 space-induced mutation materials from 7 potato varieties were planted and identified, with a focus on analyzing the variation of agronomic, economic, and yield traits. The results showed that space-induced mutation had the greatest impact on the growth period of the tested potatoes, with 83% of them being prolonged and 17% being shortened. The impact on single potato weight, yield, and commercial potato rate ranked second, with 80% positive impact and 20% negative impact. The impact on plant height, flower abundance, and creeping stem ranked third, and the impact on tuber neatness ranked fourth. Space-induced mutation had no impact on indicators such as plant shape, stem color, leaf color, corolla color, natural fertility, main stem number, tuber shape, skin color, flesh color, skin type, and bud depth. Under space-induced mutation conditions, the variation of related traits was greater in four varieties, Qingshu 9, Qingshu 168, Ningshu 19, and Ningshu 18. In subsequent work, the mutation single plant materials of these four varieties will be used as hybrid parents.
