Answer 1

The development of semi-dwarf varieties of wheat and rice has increased their production rate throughout the world. Semi-dwarf wheat is the dominant variety of wheat that accounts for almost 99 percent of total global wheat.

Complete answer:
E.Borlaug a Nobel laureate holder developed semi-dwarf varieties of wheat at the International Centre for Wheat and Maize improvement in Mexico.

Option A- Sonalika: In 1963 several semi- dwarf were developed for example- sonalika, kalyan
sona, these were high yielding and were resistant varieties that were introduced all over regions
of India where wheat is grown.
Option B- IR-8: This is a semi-dwarf variety of rice not wheat. So this is not our required answer
as they have asked about semi-dwarf varieties of wheat.
Option C- Triticum: It is most widely grown wheat or common wheat grown in the fields and it is
not a semi-dwarf variety.
Option D- Saccharum: It is not a variety of wheat, it is some species of large strong growing
grass.

So the correct answer is Option A- Sonalika.

Note: This semi-dwarf wheat has many benefits over normal wheat that is tall and wavy wheat.
The tall wheat falls off due to heavy weight of seeds on the top of plant and if head of the plant
touches the ground, it is useless. In semi-dwarf variety there is no such issues of plant
bending hence grains grow properly as these plants are dwarf. Semi-dwarf variety have short
and tough stalk so it is easy for combines to harvest it and these are also resistant to wheat rust.
