To induce mutations artificially through use of chemicals or radiations(like gamma radiations) and selecting and using the plants that have the desirable character as a source in breeding -

(1) Mutation Breeding

(2) Conventional breeding

(3) Hybrid breeding

(4) Cultivar breeding

(1) Resistance to yellow mosaic virus

(2) esculentus

(3) Resistance against shoot borer

(4) Both B and C

(1) Morphological

(2) Biochemical

(3) Physiological

(4) All of these

(1) Resistance to jassids in cotton

(2) Cereal leaf beetle in wheat

(3) Resistance to aphids in brassica

(4) Both B and C

(1) Non preference by the stem sawfly

(2) Preference by the stem sawfly

(3) Non preference by the bollworms

(4) Preference by the bollworms

(1) Attract bollworms

(2) Do not attract bollworms

(3) Attract aphids

(4) Do not attract aphids

(1) High Aspartate

(2) Low Nitrogen

(3) Low sugar content

(4) High Glutamate

(1) More than 840 million people in the world do not have adequate food to meet their daily food and nutritional requirements.

(2) Three billion people suffer from micronutrient, Protein and Vitamin deficiencies or hidden hunger because they are not able to buy enough fruits, vegetables, legumes, fish and meat

(3) High Aspartate, low sugar content and high nitrogen content in maize leads to resistance to maize stem borers.

(4) Breeding methods for insect pest resistance involve the same steps as those for any other agronomic trait such as yield or quality.

(1) Iron, Zinc

(2) Vitamin A

(3) Iodine

(4) Molybdenum

(1) Breeding crops with higher levels of vitamins and minerals

(2) Breeding crops with higher proteins

(3) Breeding crops with healthier Fats

(4) All of these
