Question

Shakti, rattan, and protina are three important lysine-rich varieties of
A. Rice
B. Pulses
C. Wheat
D. Maize
E. Cotton

Answer 1

Hint: The agricultural scientists develop several crop varieties under various projects to enhance the nutritional values of different food crops which fulfill the diet requirement and eradicate malnutrition like conditions in people.

Complete answer:
Maize is the grass that belongs to the Gramineae family and also includes rye, wheat, rice barley, sugar cane, and sorghum type of crop varieties. The maize crop is thymine rich but lysine and tryptophan deficient amino acid crop. To remove such amino acids and another nutritional component in maize, the researcher develops opaque-2 maize composite varieties called shakti, rattan, and protina under a project called all India coordinated maize improvement and release for commercial production in 1971.
-Rice is seeds of grass species and a paddy crop which is grown in standing water, this is the part of human diet and cultivated for their consumption, now 6000 varieties of rice which are influenced by the green revolution.
-Pulses is the leguminous plant which is amino acid-rich and belongs to the family Fabaceae. The FAO, a united nation food and agriculture organization recognizes 11 types of pulses that fall into our diet which fulfill the requirement of amino acid for protein.
-Wheat is the cereal crop plant and a grass plant, which is cultivated by a human to fulfill their carbohydrate needs in their diet, it is an economically important crop plant. Currently, 30,000 varieties of wheat available, and 14 species grown worldwide, and 1000 are commercially exploited. The nutritional value of wheat improved under the green revolution project.
-Cotton is a staple fibre that grows soft fibre balls around the seed and it is cultivated for fibre which is used for making textile and other purposes, currently four cultivated species are available.
Hence, the correct Option is D.

Note: The green revolution is associated with a technological enhancement in the field of agriculture to improve the crop variety, increase the yield capacity and improve the nutritional value to overcome the issue of poor agriculture practice and other purposes.
