Which plants are best to start a tissue culture lab with for steady demand?

The plants that give the most reliable demand for a tissue culture lab are ones where uniform, disease-free planting material is genuinely valued and bought in volume. Banana is the classic example, tissue culture banana plants are widely demanded for their uniformity and disease-free start, and many labs build their base on it. Other steady lines include certain ornamentals and foliage plants, some fruit crops, and selected commercial and plantation crops, depending on your region's cropping pattern. The safest strategy is to anchor your lab on one or two high-demand, proven crops like banana that have a large, repeat market near you, rather than spreading thin across many species you cannot sell. Crucially, demand must be tied to actual buyers, growers, FPOs or distributors who will lift volume, not just a general sense that the plant is popular. Match your starting crop to what is grown widely in your area, confirm offtake before you produce, and validate with operating labs and your state horticulture department which tissue culture plants have real demand and any support locally.
