Consider the following statements:
The natural rubber plantation requires a temperature above 25°C with a moist and humid climate.
The Genetically Modified (GM) rubber plant with MnSOD gene can withstand environmental stresses such as cold and drought.
In India, Tamil Nadu is a top rubber producing state.
Which of the statements given above are correct?
Correct Answer:
(A)
1 and 2 only
Recently, the world's first Genetically Modified (GM) rubber plant developed by Rubber Research Institute was planted in Assam.
The rubber plant is the first of its kind developed exclusively for this region, and is expected to grow well under the climatic conditions of the mountainous northeastern region.
Genetic modification (GM) technology allows the transfer of genes for specific traits between species using laboratory techniques.
The GM rubber has additional copies of the gene MnSOD, or manganese-containing superoxide dismutase, inserted in the plant, which is expected to tide over the severe cold conditions during winter in the northeast.
The MnSOD gene has the ability to protect plants from the adverse effects of severe environmental stresses such as cold and drought.
Natural Rubber is an equatorial crop, but under special conditions, it is also grown in tropical and sub-tropical areas. Conditions required are:
Temperature: Above 25°C with moist and humid climate.
Rainfall: More than 200 cm.
Soil Type: Rich well drained alluvial soil.
Cheap and adequate supply of skilled labour is needed for this plantation crop.
The British established the first rubber plantation in India in 1902 on the banks of the river Periyar in Kerala.
India is currently the sixth largest producer of NR in the world with one of the highest productivity (694,000 tonnes in 2017-18).
Top Rubber Producing States: Kerala > Tamil Nadu > Karnataka.
