Weekly Quiz Competition
  • Question 1
    1 / -0
    Parbhani kranti, a variety of bhindi (lady's finger), is resistant to ____.
    Solution
    Hybridisation improves the quality and yield of a crop. Parbhani Kranti is a hybrid variety of lady's finger which is produced by the backcross of Abelmoschus manihot x A. esculentus. It is a yellow vein mosaic resistant variety released in 1985 by MAU. Fruits are dark green in colour, smooth, and slender.
    So, the correct answer is option B.
  • Question 2
    1 / -0
    Breeding results in ?
    Solution
    Plant breeding is the genetic improvement of the crop in order to create desired plant types that are better suited for cultivation. The plants which are produced gives better yields and are disease resistant. The process involves two plants of same or different species which are allowed to mate in order to produce hybrids. This results in the introduction of genetic variation due to the combination of genomes of two genetically different plant species. 
    Thus, the correct answer is option A.
  • Question 3
    1 / -0
    New green revolution for nutritional value is applicable to which of the following technique ?
    Solution
    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. This can be done either through selective breeding or genetic modifications. This method is employed to improve public health. This process can be used for the production of the staple crops with higher levels of essential nutrients. This method will help to bring new green revolution in which there is the production of food in large quantities with the huge source of nutrients. 
    Thus, the correct answer is option B. 
  • Question 4
    1 / -0
    The process of developing new variety by changing the genome through X-ray or UV radiation is known as _____.
    Solution
    The process of developing new variety by changing the genome through X-ray or UV radiation is known as mutation breeding. It is a quick method to obtain genetic variation. In this process, seeds are treated with a suitable mutagen which may be chemical or radiation (gamma radiation). After the treatment with mutagens seeds are grown in the field and self-pollinated. The obtained progeny will be grown in the next crop season. It results into a mutant line which is used as mutant variety.
    Thus, the correct answer is option B. 
  • Question 5
    1 / -0
    Protein energy malnutrition can be treated by 
    Solution
    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 new varieties of legume plants can be developed through hybridisation to produce more amount of proteins in the seeds. These plants can be used for the treatment of the people suffering from protein deficiency disorders like PEM. 
    Thus, the correct answer is option B. 
  • Question 6
    1 / -0
    Which of the colour can be seen on the rice which has undergone biofortification?
    Solution
    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 which is orange-yellow in colour. Due to the presence of carotene, the colour of the rice is golden yellow. 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 B. 
  • Question 7
    1 / -0
    Which of the following plant produces beta-carotene naturally?
    Solution
    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. 
  • Question 8
    1 / -0
    A child having kwashiorkor is suggested to have 
    Solution
    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 new varieties of legume plants can be developed through hybridisation to produce more amount of proteins in the seeds. The staple crops can be developed to produce more carbohydrates and calorie-rich food. These crops can be used for the treatment of the people suffering from protein and energy deficiency disorders like PEM and kwashiorkor.
    Thus, the correct answer is option B. 
  • Question 9
    1 / -0
    Which of the following can be classified under biofortification?
    Solution
    • 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 crop like rice is fortified to produce pro-vitamin A. 
    • The consumption of the golden rice can help to prevent the deficiency disorders due to less intake of vitamin A. 
    • The rural areas generally feed on the staple crops.
    •  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 C. 
  • Question 10
    1 / -0
    Golden rice includes the expression of which of the following enzymes?
    Solution
    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.
