Step 1: Grand Naine Banana Characteristics.
Grand Naine is a high-yield Cavendish banana variety commonly grown in India. It is sterile and incapable of producing viable seeds.
Step 2: Propagation Techniques.
- Sword suckers: A conventional propagation method, but production is limited. - Tissue culture: The commercial standard, ensuring large-scale production of disease-free, uniform planting material. - Water suckers: Discouraged due to weakness and low productivity. - Seeds: Not applicable for commercial bananas as they are seedless.
Step 3: Summary.
Consequently, tissue culture is the established commercial propagation method for Grand Naine bananas in India.
Final Answer: \[\boxed{\text{Grand Naine banana is propagated commercially by Tissue culture.}}\]
Mandarin orange-Fruit Crop
Mandarin oranges (Botanical name - Citrus reticulata, Family - Rutaceae), commonly known as Santra, are the most refreshing and health-promoting juicy fruits. Besides Vitamin C, it is an excellent source of pectin and certain essential oils. The juice is advised to patients. Subtropical and tropical climates are required for the growth of santra. The trees grow luxuriantly in 1.5 m deep well-drained soils free from excess salts and having adequate content of organic matter. The important varieties are Nagpur santra (Maharashtra), Khansi mandarin (Assam), Coorg mandarin (Karnataka), Kinnow (Punjab), Emperor, Hill orange, Mudkhed seedless, and Honey (for kitchen gardening). Santra are commercially propagated by shield or ‘T’ budding on rootstocks like jamberi or rangpur lime. Average yield is 80 to 160 fruits per tree.
