Question

Parbhani Kranti is
I)Okra variety resistant to shoot and root borers.
II)Bhindi resistant to yellow mosaic virus
III)A wild variety of bhindi
IV)Produced by sexual hybridization

(a)I, II, and III only correct
(b)II and IV only correct
(c)III and IV only correct
(d)I and II only correct

Answer 1

Hint: Parbhani Kranti racist against organisms that are obligate parasites and the term was coined to describe it as contagium vivum fluidum. Parbhani Kranti is a genetically engineered variety.

Complete answer:
ParbhaniKranti is the name given to the scientifically engineered variety of bhindi which is also known as Abelmoschusesculentus. This specifically engineered variety of okra or bhindi is resistant to the yellow mosaic virus which has either RNA or may have DNA as their genetic material but never both are present in the same organism. This particular variety of okra produced bi sexual hybridization are mutational breeding of a variety which is resistant to the yellow mosaic virus and another which is a wild variety of okra. The wild species of okra which was selected for the hybridization process produce ParbhaniKrantiis scientific termed asAbelmoschusmanihot.

Additional Information: -Mutations are 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 as 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.
-There are examples of some of such high yielding varieties of wheat plants like Lerma Rojo-64 and Sonora-64.
-One high yielding variety of rice which was produced through induced mutation by treating it with gamma rays is known as Pelita-1.
So, the correct option is,” II and IV only correct”.

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 Gamma rays for genetic mutations induced and organisms, X-rays, ethyl methyl sulfates, etc. can also be used.
