Weekly Quiz Competition

Question 1
1 / -0

Picking up only homozygous plants for further cultivation is known as

A
Mass selection

B
Pure-line selection

C
Clone

D
Acclimatization

Solution

Mass selection is the simplest, easiest and oldest method of selection, where individual plants are selected based on their phenotypic performance and bulk seed selection proved to be quite effective in maize improvement at the initial stages but its efficacy especially for improvement of yield, soon came under severe criticism that culminated in the refinement of the method of mass selection.
Pure-line selection generally involves three more or less distinct steps: (1) numerous superior appearing plants are selected from a genetically variable population, (2) progenies of the individual plant selections are grown and evaluated by simple observation, frequently over a period of several years, (3) when selection can no longer be made on the basis of observation alone, extensive trials are undertaken, involving careful measurements to determine, whether the remaining selections are superior in yielding ability and other aspects of performance.
Acclimatization is the process in which an individual organism adjusts to a gradual change in its environment, such as a change in temperature, humidity, photoperiod or pH, allowing it to maintain performance across a range of environmental conditions.
Clone is an organism or cell, or group of organisms or cells, produced asexually from one ancestor or stock, to which they are genetically identical.
Thus, the correct answer is option B.
Question 2
1 / -0

Cutting of anthers from the intersexual flowers, called as

A
Emasculation

B
Male sterile line

C
Artificial pollination

D
Selective or differential reproduction

Solution

Emasculation involves the removal of stamens from bisexual flowers of the female parents in order to avoid self pollination in these flowers. It is done before the anthers are mature.
Question 3
1 / -0

Explant is?

A
Plant collected after harvesting

B
Exploited part of a plant

C
Small part of the plant meant for tissue culture

D
Uprooted for transplantation

Solution

Correct Option: C
Explanation:

Explant culture is a technique used for the isolation of cells from a piece or pieces of tissue. Tissue harvested in this manner is called an explant. It can be a portion of the shoot, leaves or some cells from a plant.
Question 4
1 / -0

The aim of plant breeding programme is to produce

A
Disease-free varieties

B
High-yielding varieties

C
Early-maturing varieties

D
All of the above
Solution
- Plant breeding is a program in which the species are altered with their genetic sequences to increase their value and life.
- Their aim is to produce disease-free, high-yielding, and early maturing varieties.
- So, the correct answer is option D.
Question 5
1 / -0

Evaluation of newly evolved varieties is carried out by

A
All agricultural universities

B
Indian Council of Agricultural Research

C
Indian Agricultural Research Institute

D
National Bureau of Plant Genetic Resources

Solution

The Indian Council of Agricultural Research (ICAR) is an autonomous organisation with a vision to plan, undertake and promote and coordinate education and research in the field of agriculture, animal husbandry and allied sciences. It carries out evaluation of newly evolved varieties. Agricultural universities are mostly public universities that have vision of teaching, research and extension in agriculture and related disciplines. Indian Agricultural Research Institute (IARI), the Pusa Institute, was established in 1905 at Pusa (Bihar) and serve to supervise and observe the ICAR institutions. IARI is the leading institution for education and extension of agricultural research in the country. The National Bureau of Plant Genetic Resources (NBPGR) headquarters is at New Delhi; it serve to explore and collect the indigenous and exotic plant genetic resources.
Thus, the correct answer is option B.
Question 6
1 / -0

A clone is a group of individuals obtained through

A
Hybridisation

B
Cross-pollination

C
Self-pollination

D
Micropropagation

Solution

Micropropagation is a technique of growing plants from meristematic tissue or somatic cells of plants. Plants with desirable traits are chosen and grown on a suitable nutrient media under controlled and aseptic physical conditions. All the individual plants obtained by this technique are genetically identical and are clones of each other. Thus the correct answer is option D.
Question 7
1 / -0

What is micropropagation?

A
Germination of seed with cotyledons above the soil.

B
A technique to obtain new plants by cultivating the cells or tissues in culture medium.

C
The mature stage of endosperm.

D
To manufacture hormones.

Solution

Micropropagation is a technique to obtain new plants by cultivating the cell or tissue in culture medium through tissue culture.
So, the correct answer is 'A technique to obtain new plants by cultivating the cells or tissues in culture medium'
Question 8
1 / -0

Micropropagation is

A
Germination of seed with cotyledons above the soil

B
A technique to obtain new plants by cultivating the cells or tissues in culture medium

C
The mature stage of endosperm

D
To manufacture sperm

Solution

Micropropagation is the method of large production of plantlets in a less time. In this method, a small piece of plant tissue (explant) is cultured in a sterile medium which later develops into new plantlets. The offsprings produced by this methods are the exact copy of their parent plant.
Thus, the correct answer is option B.
Question 9
1 / -0

Which of the following is correctly matched?

A
Apiculture - honey bee

B
Pisciculture - silk moth

C
Sericulture - fish

D
Aquaculture - mosquito
Solution
Correct option: A
Explanation:
Apiculture is the raising and maintaining of honey bees for the commercial production of honey and other bee products.
Fish farming or the breeding, rearing and transplantation of fish by artificial means is pisciculture.
Sericulture is the rearing of silkworms for the production of silk, also known as silk farming.
Aquaculture is the farming of aquatic animals which includes fishes, crustaceans, aquatic plants etc. It is also known as aquafarming.
Hence, the correctly matched pair is Apiculture and honey.
Question 10
1 / -0

The method of asexual reproduction in plants in which callus is produced is

A
Layering

B
Grafting

C
Regeneration

D
Micropropagation

Solution

The process where plant cells containing meristematic cells are used to produce a mass of undifferentiated cells called callus is called micropropagation.
So the correct answer is "Micropropagation".
