Plant Tissue Culture

Planting Material

Sword suckers weighing approximately 500-1000 gm are commonly used as propagating material. Suckers generally may be infected with some pathogens and nematodes. Similarly due to the variation in age and size of sucker crop is not uniform, harvesting is prolonged and management becomes difficult.

Therefore, in-vitro clonal propagation i.e. Tissue culture plants are recommended for planting. They are healthy, disease free, uniform and authentic. Properly secondary hardened seedlings are only recommended for planting.

Advantages of Tissue Culture Planting Material

• True to the type of mother plant under well management.

• Pest and disease free seedlings.

• Uniform growth, increases yield.

• Early maturity of crop - maximum land use is possible in low land hoping country like India.

• Round the year planting possible as seedlings are made available throughout the year.

• Successive two ratoons are possible in short duration which minimizes cost of cultivation.

• No staggered harvesting.

• 95% - 98% plants bears bunches.

• New varieties can be introduced and multiplied in short duration.

Planting Time

Planting of tissue culture Banana can be done throughout  the year except when the temperature is too low or too high. Facility of drip irrigation system is important. There are two important seasons in Maharashtra, India;

Mrig Baug (Kharif) Month of planting June - July.

Kande Baug (Rabi) Month of planting October - November.

Crop Geometry

Traditionally banana growers plant the crop at 1.5m x 1.5m with high density, however plant growth and yields are poor because of competition for sunlight. Various trials are conducted at Jain Irrigation System R&D farm with Grandnaine as cultivar. And then suitable spacing of 1.82m x 1.52m is being recommended, it accommodates 1452 plants per acre (3630 plants per hectare) keeping row direction North-South with wide spacing 1.82m between the rows. The region like north India, coastal belt and where humidity is very high and temp falls down up to 5-7ºC, the planting distance should not be less than 2.1m x 1.5m.
