| Abstract: | Minitubers were produeed by soilless culture of virus free potato test tube plantlets in greenhouse.9 times of topping and 8 times of earthing up resulted in an average of 212 8 tubers/plantlet,180 days after transplantation,and the commercial tubers(more than 1 g)reached 158 2 tubers/plantlet,210 days after transplantation.There was a signicant positive correlation(r=0 9023)between the times of topping and earthing up and the number of axillary buds and a significant positive correlation(r=0 9470)between times of toppiny and earthing up and the number of minitubers per plantlet.Positive correlation between times of topping and earthing up and the number of stolon also existed. |
| Keywords: | virus free plantlets topping earthing up axillary buds |
