A
Rice

B
Sugarcane

C
Onion

D
Wheat

Solution

Norman Borlaug is called as father of green Revolution. He has developed highly recognized and appreciated cultivating variety of wheat that increased the productivity of wheat many fold in different parts of world including India.
Question 2
1 / -0

An organism used as bio-fertilizer for raising soybean crop is

A
Azospirillum

B
Rhizobium

C
Nostoc

D
Azotobacter

Solution

Bio-fertilizers are used to grow plants without using chemical fertilizers. Certain bacteria and fungi have ability to increase nitrogen or other nutrients in the soil. Azotobacter is used as bio-fertilizers for raising soybean crop.
Question 3
1 / -0

In tissue culture medium, embryoids formed from the pollen grains is due to

A
Test tube culture

B
Organogenesis

C
Double fertilisation

D
Cellular totipotency

Solution

In tissue culture medium, embryoids formed from the pollen grains are due to cellular totipotency. Totipotency is the ability of plants parts to develop whole new plants.
Question 4
1 / -0

Desired improved varieties of economically useful crops are raised by

A
Natural selection

B
Hybridization

C
Bio-fertilizer

D
Mutation

Solution

Plants with desired traits are obtained by hybridization between two varieties having desired traits. Economically useful crops like wheat, rice, pulses are raised for higher yields, resistant to disease etc. by hybridization.
Question 5
1 / -0

Breeding crops with higher levels of minerals, vitamins or higher protein and healthier fats is called

A
Somatic hybridization

B
Bio fortification

C
Bio magnification

D
Micro propagation

Solution

Bio fortification is the idea of breeding crops to increase their nutritional value. This can be done either through conventional selective breeding, or through genetic engineering.
Question 6
1 / -0

Bagging is done to

A
Avoid cross pollination

B
Avoid self-pollination

C
Prevent contamination from unwanted pollen

D
Achieve desired pollination

Solution

Bagging is the method of covering emasculated flowers to prevent contamination from unwanted pollen. Butter paper or similar other substance is used to cover the flower.
Question 7
1 / -0

Modification and adjustment of an organism to local environment is called

A
Selection

B
Introduction

C
Quarantine

D
Acclimatization

Solution

Modification and adjustment of an organism to local environment is called acclimatization. The newly developed varieties of crops are acclimatized in different environmental condition before releasing to farmers for raising crops.
Question 8
1 / -0

Which variety of wheat is used as donor for high protein?

A
Atlas 66

B
IR-8

C
Himgiri

D
Sonalika

Solution

Plant hybridization is also done to increase in nutritive value of crop plants. Wheat variety Atlas 66 has high protein value that is used as donor for high protein variety.
Question 9
1 / -0

In order to obtain disease-free plants through tissue culture techniques, the best method is

A
Protoplasm culture

B
Embryo rescue

C
Anther culture

D
Meristem culture

Solution

Disease free plants can be obtained by the tissue culture of meristematic tissues present at shoot tips. The newly formed cells are generally disease free and plants obtained from this are also disease free.
Question 10
1 / -0

The conventional method of breeding for disease resistance

A
Mutation and selection

B
Protoplasm fusion

C
Hybridisation and selection

D
Germplasm fusion

Solution

The conventional method of breeding for disease resistance varieties of plant is hybridization in which two varieties having desired traits and selection by raising the crop for several times.
