Abstract：The budding property and endurance to storage of sweet potato seeds harvested in different growth periods (T1,158 days; T2,127 days; T3, 104 days) were studied taking edible -type cultivar Taizhong 6 as experimental material .The results showed that T 3 treatment obtained the highest total seedling number, which was 262.The seedling height ranged from 31.0~37.6 cm.There were no differences in aver-age bud diameter between the three treatments .The average single weight and total weight of T 3 seedlings both were the highest , which were 11 .61 g per plant and 2 898 .84 g respectively .In the condition of nearly total weight of sweet potato seeds , the T2 treatment had the most big sweet potato (>200 g) as 66;the next was T1;T3 had the fewest as 1.The number of medium-sized (50~200 g) and small (<50 g) sweet potato were the most in T3, which were 118 and 92 respectively.The disease rate of T1 was the highest as 6.25%, and the main diseases were soft rot and dry rot .T3 had the lowest disease rate .In conclusion, the sweet potato seeds harvested after transplanted for 158 days had the worst endurance to storage , while those harvested after transplanted for 104 days had the best .
