Tissue culture means cloning and micro-propagation of tissues of the selected Elite plants and daughter suckers. The process consists of five important steps: Initiation, Multiplication, Shooting & rooting, Primary Hardening in green houses and Secondary Hardening in shade houses. Strict adherence to aseptic standards and micro-climatic conditions and care during the hardening process alone can ensure success.
The Company has pioneered tissue culture of ‘Grand Nain’ variety of banana since 1994-95. The Jain Tissue Culture laboratory has successfully micro-propagated and sold over 2 million ‘Grand Nain’ banana plants with outstanding success. It is the largest Banana Tissue Culture laboratory in the country. The farmers have increased their productivity from an average of 12 kg to over 26 kg per bunch per year and have consecutively taken crops with two ratoons in about 30 months.

Agro Climate
Banana is basically a tropical crop, grows well in temperature range of 13ºC – 38ºC with RH regime of 75-85%. In India this crop is being cultivated in climate ranging from humid tropical to dry mild subtropics through selection of appropriate varieties like Grandnaine. Chilling injury occurs at temperatures below 12ºC. The normal growth of the banana begins at 18ºC, reaches optimum at 27ºC, then declines and comes to a halt at 38ºC. Higher temperature causes sun scorching. High velocity wind which exceeds 80 km phrs damages the crop.
Soil
Soil for banana should have good drainage, adequate fertility and moisture. Deep, rich loamy soil with pH between 6-7.5 are most preferred for banana cultivation. Ill drained, poorly aerated and nutritionally deficient soils are not suitable for banana. Saline solid, calcareous soil are not suitable for Banana cultivation. Avoided soil of low laying areas, very sandy & heavy black cotton with ill drainage.
A soil that is not too acidic & not too alkaline, rich in organic material with high nitrogen content, adequate phosphorus level and plenty of potash are good for banana.
Varieties
In India banana is grown under diverse conditions and production systems. Selection of varieties, therefore is based on a large number of varieties catering to various kinds of needs and situations. However, around 20 cultivars viz. Dwarf Cavendish, Robusta, Monthan, Poovan, Nendran, Red banana, Nyali, Safed Velchi, Basarai, Ardhapuri, Rasthali, Karpurvalli, Karthali and Grandnaine etc..
Grandnaine is gaining popularity and may soon be the most preferred variety due to its tolerance to biotic stresses and good quality bunches. Bunches have well spaced hands with straight orientation of figures, bigger in size. Fruit develops attractive uniform yellow colour with better self life & quality than other cultivars.
Land Preparation
Prior to planting banana, grow the green manuring crop like daincha, cowpea etc. and burry it in the soil. The land can be ploughed 2-4 times and leveled. Use ratovator or harrow to break the clod and bring the soil to a fine tilt. During soil preparation basal dose of FYM is added and thoroughly mixed into the soil.
A pit size of 45cm x 45cm x 45cm is normally required. The pits are to be refilled with topsoil mixed with 10 kg of FYM (well decomposed), 250 gm of Neem cake and 20 gm of conbofuron. Prepared pits are left to solar radiation helps in killing the harmful insects, is effective against soil borne diseases and aids aeration. In saline alkali soil where PH is above 8 Pit mixture is to be modified to incorporate organic matter.
Addition of organic matter helps in reducing salinity while addition of purlite improves, porosity and aeration. Alternative to planting in pits is planting in furrows. Depnding on soil strata one can choose appropriate method as well as spacing and depth at which plant is required to be planted.
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 the 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 hardened secondary seedlings are only recommended for planting
