II: | Genetic variability is the root of any breeding programme. |
1. Both I and II are true and II explains I.
2. Both I and II are true but II does not explain I.
3. I is true but II is false.
4. I is false but II is true.
Before releasing new cultivars in plant breeding programs, their testing includes all the following except:
1. | growing these in the research fields and recording their performance under ideal fertiliser application, irrigation, and other crop management practices. |
2. | testing the materials in farmers’ fields, for one growing season at selected locations in the country |
3. | comparison to the best available local crop cultivar – a check or reference cultivar |
4. | taking care of all patent and legal issues |

The Indian Agricultural Research Institute, New Delhi, has released several vegetable crops that are rich in vitamins and minerals. Identify the incorrectly matched:
1. | vitamin A enriched: carrots, spinach, pumpkin; |
2. | vitamin C enriched: bitter gourd, bathua, mustard, tomato; |
3. | iron and calcium enriched: spinach and bathua; |
4. | Omega fatty acids enriched: beans - broad, lablab, French and garden peas. |
The plantlets produced during plant tissue culture are called somaclones because:
1. | They can be produced in a very short span of time |
2. | They are the result of the somatic hybridization of two cells |
3. | The gametes develop parthenogenetically to produce genetically identical plantlets |
4. | They are genetically identical to the original plant from which they were grown |
Consider the following statements regarding bird flu:
I: | Viruses causing bird flu belong to Influenza virus A strain |
II: | The most pathogenic strain of this virus causing bird flu is H1N1 |

IV: | A human vaccine is available to control the spread of disease in human populations. |
Of the above statements, the correct are:
1. | I and III only | 2. | II and IV only |
3. | I, III and IV only | 4. | I, II, III and IV |
