Abstract: Red-skin potato is one of the important commercial crops which have promotional value in the current market. The shoots from tubers of red-skin potato were used as sterile materials to study the induction and proliferation of test-tube plantlet and micro-tuber of red-skin potato. The results showed that cultured in MS basal medium with 0.5 mg/L 6-BA, 0.17% activated carbon and 20 g/L sucrose for 30 days, the proliferation coefficient of test-tube plantlet was 8.6, and in MS basal medium with 0.5 mg/L 6-BA, 0.17% activated carbon and 100 g/L sucrose for 30 days, the induction rate of micro-tuber reached 62.5%. The average diameter of micro-tuber was 4.2 mm.
