Which of the following options represents the correct sequence of steps in somatic hybridization?
1 Isolation of plant cells → Fusion of protoplasts from different plant varieties → Production of somatic hybrids → Digestion of cell wall.
2 Isolation of plant cells → Digestion of cell wall → Fusion of protoplasts from different plant varieties → Production of somatic hybrids.
3 Isolation of plant cells → Fusion of protoplasts from different plant varieties → Digestion of cell wall → Production of somatic hybrids.
4 Isolation of plant cells → Fusion of protoplasts from different plant varieties → Production of somatic hybrids.
Explanation:
Somatic hybridization is the production of hybrid plants from hybrid protoplasts. For the purpose, single plant cells are isolated from the selected parent plant varieties having desirable genetic traits. Digestion of cell walls is performed to obtain protoplasts. The protoplasts of selected plant varieties are fused to obtain hybrid protoplasts which in turn are cultured to produce somatic hybrids.

A technique of micropropagation is [NEET-2015]
1 somatic embryogenesis
2 protoplast fusion
3 embryo rescue
4 somatic hybridization
Explanation:
Microprogation refers to the production of plants by growing explant on the synthetic growth medium under aseptic conditions. Somatic hybridization produces somatic hybrids by culturing the hybrid protoplasts on growth medium under controlled conditions.

[NEET-2015] Which of the following enhances or induces the fusion of protoplasts?
1 IAA and kinetin
2 IAA and gibberellins
3 Sodium chloride and potassium chloride
4 Polyethylene glycol and sodium nitrate
Explanation:
Polyethylene glycol and sodium nitrate are the chemicals that facilitate the fusion of protoplasts. This is required to facilitate the production of hybrid protoplasts which are then cultured to produce somatic hybrid plants.

Select the mismatch from the given options.
1 Tissue culture: Jaya and Ratna
2 Somatic hybridization: Pomato
3 Micropropagation: Tomato, banana, apple
4 Meristem culture: Banana, sugarcane, potato
Explanation:
Jaya and Ratna are the semi-dwarf hybrid varieties of rice developed in India for better production of rice crops. These varieties were developed by plant breeding techniques. Somatic hybridization, micropropagation, and meristem culture are the applications of tissue culture to develop crop varieties with desired agronomic and other traits.
