Abstract
Availability of certified potato seed tubers is a major problem in potato cultivation in Indonesia. This was partly caused by lack availability of breeder seeds for the certification program. This research was conducted to assess the use of apical stem cuttings as a system for mass-production of G1 seed tuber under hydroponic condition. Experiment was conducted in a screen house located in Sembalun Timba Gading, Sembalun District, West Nusa Tenggara, at altitude of 1,200 m above sea level. The cuttings were planted in seedling trays filled with mixtures of rice paddy husk and coco-peat (4:1), and weremaintained for 2 weeks with daily watering using a mixture of hydroponic nutrients. Rooted cuttings were transferred to hydroponic frame filled with mixtures of rice paddy husk and coco-peat (4:1) (aggregate culture), and planted at different planting space, nutrients were supplied through an automated system twice a day, and insecticides/fungicides were applied as appropriate. All cuttings treated with IAA at concentration of 1, 3 and 5 ppm were successfully rooted, and the growth was influenced by concentration of IAA and length of IAA treatment. The best seedling growth was achieved on cutting treated with 1 ppm IAA for 30 minutes. In addition, planting space influenced cutting growth and production. Better growth rate and G1 tuber were obtained at spacing of 15 x 15 cm, at which each cutting produced 5,2 tubers. However, the size of tuber produced in each treatment was mostly large for G1 seedlings (more than 20 gr each). The results indicate that apical cutting is a possible approach for mass-propagation of Go plants. Further work is now underway to optimize the system and to evaluate field performance of G1 tuber for production of quality G2 potato seed tuber
