The seedling, dry-raised experiments have four seedling raising methods, including dry -raised seedling, water-raised seedling in plastic trays and water cultivation of seedling. The effect of seedlings quality of Japonica Xi- giant embryo-1 was studied under different seedling raising methods, conventional japonica rice Hexi-22-2 as control. The results indicated that, under water-raised seedling and dry-raised seedlings, the seedling of Japonica Xi- giant embryo -1 has strong growth advantage, suitable seedling height, thick stem, more accumulation of dry matter per plant, and the content of soluble protein and superoxide dismutase and the activity of root were higher than that under the other seedling raising methods. Therefore, according to the seedling quality, water-raised seedling and dry -raised seedlings were beneficial to breed the vigorous seedling for the Japonica Xi- giant embryo - 1.
