Question

Kalyan sona is
A. High yielding variety of rice
B. High yielding variety of wheat
C. High yielding variety of millet
D. High yielding variety of tobacco

Answer 1

Hint: Kalyan sona is a genetically modified plant for high yield. Plants are genetically engineered to give high yield and to be disease resistant. Kalyan Sona is such an example of genetically modified plant to give better yield than the normal yield. As we know that only limited land is fit for cultivation, India has to strive to increase yield per unit area from existing land to meet the requirement of growing population.

Complete answer:
B) Kalyan sona is a high yielding variety of wheat, is the correct answer.
Kalyan Sona is a genetically modified wheat also known as dwarf wheat to deliver high yield to farmers. This dwarf wheat is abundant in starch and gluten and proves to be nutritious. These plants are also resistant to different drugs and diseases.
Wheat production increased from 11 million tons to 75 million tons during the year 1960 to 2000. Various plant breeding techniques led to the dramatic increase in food production. This phase is often referred to as the green revolution.
Nobel laureate Norman E. Borlaug developed semi- dwarf varieties of wheat at the international center for wheat and maize improvement, situated in Mexico.
In 1963, several semi dwarf varieties of wheat like Kaylan sona and sonalika were introduced in the wheat growing belt of India. These semi-dwarf varieties were high-yielding and disease-resistant varieties of wheat.

Note:
The semi-dwarf variety of wheat has many benefits over the normal tall and wavy variety of wheat. The tall wheat fell down due to the heavyweight of seeds on the top of the plant and touched the ground when the wind blew. When the head of the plant touches the ground, it is useless. In the semi-dwarf variety, there is a tough and short stalk so there is no such kind of problem of plant bending hence grains grow properly and can be harvested easily.
