Questions Related to plant breeding for food production

Which of the following plant produces beta-carotene naturally?

  1. Rice

  2. Tobacco

  3. Potato

  4. None of the above


Correct Option: A
Explanation:

Biofortification is the method in which the food is added or supplemented with the required nutrients. The staple crop like rice is fortified to produce the precursor of vitamin A. Golden rice is the transgenic rice in which beta-carotene synthesizing gene psy and crtl are incorporated by the help of genetic engineering. Beta-carotene is the precursor of the vitamin A. The consumption of the golden rice can help to prevent the deficiency disorders due to less intake of vitamin A. 

Thus, the correct answer is option A. 

Which of the following agronomic trait can be fortified in beans?

  1. Virus resistance

  2. Heat tolerance

  3. Drought tolerance

  4. All of the above


Correct Option: D
Explanation:

Biofortification is the method in which the food is added or supplemented with the required nutrients. It is a process of breeding crops with higher levels of vitamins, minerals, proteins, and fat content. The beans are fortified with iron, proteins and other nutrients. In order to obtain more yield, breeding of the plant is performed to obtain the resistant variety of plants. Resistance to virus, heat and drought tolerance are some of the characteristics which are selected for breeding.

Thus, the correct answer is option D. 

Zinc, iron and vitamin A deficiency can be sorted out by 

  1. Biofortification

  2. Bioremediation

  3. Biofertilizers

  4. Bioaugmentation


Correct Option: A
Explanation:

Biofortification is the method in which the food is added or supplemented with the required nutrients. This process can be used for the production of the staple crops with higher levels of essential nutrients. The staple crops like wheat are fortified with zinc and the golden rice, rice is fortified to produce beta-carotene. Rice and sweet potato can be fortified with iron. The rural areas generally feed on the staple crops and suffer from nutrient deficiency. The consumption of this fortified crops will prevent the deficiency disorders and improve the health of the people in the rural areas. 

Thus, the correct answer is option A. 

Orange super bananas is a common food produced by biofortification are common in areas where 

  1. Banana is a staple food

  2. Vitamin A deficiency prevails

  3. Vitamin D deficiency prevails

  4. Both A and B


Correct Option: D
Explanation:

Biofortification is the method in which the food is added or supplemented with the required nutrients. The bananas are generally consumed by all the people. The regions where banana are used as staple food, the banana can be fortified with essential nutrients like beta-carotene production which is the precursor of vitamin A. Due to the presence of carotene, the colour of the banana is orange, and so called as the orange super bananas. The consumption of this banana can help to prevent the deficiency disorders due to less intake of vitamin A. 

Thus, the correct answer is option D. 

Breeding of crops with high levels of minerals, vitamins and proteins is called

  1. Micropropagation

  2. Somatic hybridisation

  3. Biofortification

  4. Biomagnification


Correct Option: C

Which of the following is incorrectly paired?

  1. Wheat - Himgiri

  2. Milch - Sahiwal

  3. Rice - Ratna

  4. Pusa Komal - Brassica


Correct Option: D
Explanation:

Pusa Komal is a variety of cowpea (Vigna unguiculata). Developed by IARI, New Delhi and is resistant to bacterial blight diseases. It belongs to family Fabaceae.

So, the correct answer is 'Pusa Komal - Brassica'

Correct Option: C

Hairy leaves of many plants are associated with ________________.

  1. Resistance to insect pests

  2. Resistance to viruses

  3. Resistance to fungi

  4. Resistance to bacteria


Correct Option: A
