Which among of the following is commonly used for creation of a new character or trait not found in the parental type?
1 Mutation breeding
2 Out breeding
3 Inbreeding
4 Cross breeding
Explanation:
Mutation breeding is the process of exposing seeds to chemicals or radiation in order to generate mutants with desirable traits to be bred with other cultivars. Eg., In Mung bean, resistance to yellow mosaic virus and powdery mildew were induced by mutation.

Statement A : Pusa Sadabahar is a food variety resistant to turnip mosaic virus. Statement B : Emasculation is mandatory in case of bisexual flowers
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Pusa Sadabahar is a food variety resistant to Chilly mosaic virus, Tobacco mosaic virus and Leaf curl Emasculation is mandatory in case of bisexual flowers

Statement A : Parbhani Kranti is resistant to rust disease Statement B : Mutation breeding is carried out by inducing mutations in plants by high energy rays.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Resistance to yellow mosaic virus in bhindi ( Abelmoschus esculentus ) was transferred from a wild species and resulted in a new variety of A. esculentus called Parbhani kranti. Mutation is possible to induce mutations artificially through use of chemicals or radiations like gamma radiations
