EFFECT OF INOCULATION DENSITY ON POTATO MICROPROPAGATION

The in vitro microplant growth of two potato genotypes viz., Kufri Jyo ti and Kufri Chandramukhi was affected by inoculation density. After 2 weeks of culture, maximum microshoot length and number of roots/micro plant were observed at an inoculation density of five single node cutt ings per culture tube. There was difference in response between the ge notypes for me,an number of nodes/microplant. The number of explants c ultured per tube did not significantly change microplant growth produc ed over 4 weeks of culture.
