| 2. | Saccharum officinarum |
| 3. | A hybrid of Saccharum barberi and Saccharum officinarum |
| 4. | A hybrid of Saccharum officinarum and a grass Aegilops squarrosa |
| Assertion (A): | Breeding and development of cultivars resistant to disease enhance food production in areas where the disease is prevalent. |
| Reason (R): | Resistance to a disease is determined by the genetic constitution of the host plant. |
| 1. | Both (A) and (R) are false. |
| 2. | Both (A) and (R) are true but (R) does not explain (A). |
| 3. | (A) is true but (R) is false. |

Use of certain chemicals and radiation to change the base sequences of genes of crop plants is termed:
1. recombinant DNA technology
2. transgenic mechanism
3. mutation breeding
4. gene therapy.
The biggest constraint of plant breeding is:
1. availability of desirable gene in the crop and its wild relatives
2. infrastructure
3. trained manpower
4. transfer of genes from unrelated sources.
Breeding crops with higher levels of vitamins and minerals, or higher protein and healthier fats is called:
| 1. | Bioremediation | 2. | Biofortification |
| 3. | Food adulteration | 4. | Biomagnification |
