Question 1
1 / -0.25

Germplasm collection is a:

A
Collection of specimens of all the species of an area in a herbarium or botanical garden

B
Collection of seeds or pollen of rare and threatened species of a group or area

C
Collection of plants or seeds having diverse alleles of all genes in crop

D
Collection of modern varieties of a cropExplanation:

Solution

Germplasm collection is the collection of plant parts or seeds that have all different alleles of all genes in a crop. It can be used for plant breeding purpose in future.
Question 2
1 / -0.25

Which of the following disease is caused by bacteria?

A
Black rot of crucifers

B
Late blight of potato

C
Brown rust of wheat

D
Red rot of sugarcane

Solution

Many diseases of plants are caused by bacteria such as black rot of crucifers. Late blight of potato, red rot of sugar cane is caused by fungi. Brown rust of wheat is also a fungal disease.
Question 3
1 / -0.25

Which one of the following is linked to the discovery of Bordeaux mixture as a popular fungicide?

A
Black rust of wheat

B
Loose smut of wheat

C
Bacterial leaf blight of rice

D
Downy mildew of grapes

Solution

Bordeaux mixture is popular fungicide that prevents the growth of fungi. This mixture is discovered by getting clue from downy mildew of grapes. This mixture is effective against plants as well as human.
Question 4
1 / -0.25

Aphids or plant lice cause major damage to the crops. Which variety of crops has been developed for its resistance towards the attack of aphids?

A
Pusa Gaurav

B
Pusa Sem 2

C
Pusa Swami

D
Pusa A-4

Solution

aphids or plant lice caused damage to crops by making bore into stem, leaves as well as seeds. Aphid ’s resistant variety of crops has been developed at Pusa agricultural institute as PusaGaurav.
Question 5
1 / -0.25

The technique of fusion of the protoplasts from two different plant varieties is called?

A
Cloning

B
Micro propagation

C
Soma clones

D
Somatic Hybridisation

Solution

The technique of fusion of the protoplasts from two different plant varieties is called somatic hybridization. Two varieties of crop that can be fertilized can be hybridized by this method.
Question 6
1 / -0.25

Artificial mutation can be created by _____?

A
Alpha radiation

B
UV radiation

C
X-ray radiation

D
Gamma radiation

Solution

Mutation is the sudden change in the base pair of genome naturally or artificially. Gamma radiation is used to create artificial hybridization in plants to create variations.
Question 7
1 / -0.25

Green revolution was dependent to large extent on plant breeding technique for development of

A
High yielding and disease resistant

B
Disease resistance only

C
High protein content and high yielding

D
High yielding only

Solution

Green revolution is mainly dependent on plant breeding technique for high yielding and disease resistant variety in wheat, rice and maize etc.
Question 8
1 / -0.25

Norman Borlaug the “father of green Revolution ”has developed highly recognized and appreciated cultivating variety of___________.

A
Sugarcane

B
Rice

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 9
1 / -0.25

An organism used as bio-fertilizer for raising soybean crop is____________.

A
Rhizobium

B
Azospirillum

C
Azotobacter

D
Nostoc

Solution

Rhizobium is nitrogen-fixing bacteria for leguminous crops (like soybean, groundnut, mung, chickpea, all types of beans, methi, alfalfa) in association with the roots of leguminous plants in the form of root nodules.
These microorganisms fix the atmospheric nitrogen in the roots and make it available to plants, which plants cannot fix directly and makes the soil fertile and also increases the plant health.
Whereas Nostoc, Azotobactor, and Azospirilum are the nitrogen-fixing bacteria for crops like tea, coffee, rice, etc .
Question 10
1 / -0.25

Desired improved varieties of economically useful crops are raised by_________.

A
Hybridization

B
Bio-fertilizer

C
Mutation

D
Natural selection

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.
