Question

Assertion: Parbhani Kranti is a transgenic variety of Abelmoschus esculentus
Reason: Mutation breeding is useful for improving new varieties
(A) Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
(B) Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
(C) Assertion is correct but Reason is incorrect
(D) Both Assertion and Reason are incorrect

Answer 1

Hint: Abelmoschus esculentus is the scientific name which is given to the Okra, also known as ladyfinger. Some other names are bhindi, bamia, or gumbo, and is a flowering plant valued for its edible green seed pods.

Complete answer:
Parbhani Kranti is a transgenic type of okra i.e. ladyfinger which is produced through mutation breeding.
Mutation breeding which is very often said as "variation breeding", is the process of exposing seeds to chemicals or radiation to get mutants with desirable traits to be bred with other cultivars.
-Mutations are known to be the genetic manipulation that occurs due to changes in inheritance and is uncertain and random.
-Some types of mutations are genetically induced and are hence termed induced mutations. These are the processes through which scientifically engineered plans are created to achieve a specific purpose.
-Crosses to produce genetically modified plants are often done for example between a high-yielding variety of a plant is sexually hybridized along with another plant which is supposed, pest resistant.

Additional Information:
Abelmoschus esculentus is an annual growing plant that has a height up to 1 m (3ft 3in).
It's in flower from July to September. The species is hermaphrodite (has both male and feminine organs) and is pollinated by Bees.
This plant is suitable for different varieties of soil like light (sandy), medium (loamy), and heavy (clay) soils and prefers well-drained soil. Suitable pH: acid, neutral, and basic (alkaline) soils and may grow in very alkaline soils.
It cannot grow within the shade. It prefers moist soil.

So, the correct answer is ‘Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion’.

Note:

• • Multiple diseases can be prevented without using pesticides by just mutation breeding and hence this mutation breeding process is quite advantageous.

-Except for the use of some rays like the gamma rays for genetic mutations induced and organisms, X-rays, ethyl methyl sulfates, etc. can also be used and are found to be successful.
