Consider the following two statements:
| I: | An effective germplasm collection is the prerequisite of any successful plant breeding programme. |
| 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 |
Hisardale is a new breed of:
| 1. | Sheep developed by crossing Bikaneri ewes and Marino rams. |
| 2. | Sheep developed by crossing Bikaneri rams and Marino ewes. |
| 3. | Goat developed by crossing Bikaneri ewes and Marino rams. |
| 4. | Goat developed by crossing Bikaneri rams and Marino ewes. |
Arrange the following steps of a plant breeding program in a correct chronological manner:
| I. | Selection and testing of superior recombinants |
| II. | Collection of variability |
| III. | Cross hybridisation among the selected parents |
| IV. | Evaluation and selection of parents |
| V. | Testing, release, and commercialisation of new cultivars |
| 1. | II, IV, I, III, V | 2. | IV, I, II, III, V |
| 3. | II, IV, III, I, V | 4. | IV, III, II, I, V |
Conventional breeding is often constrained by the availability of a limited number of disease-resistance genes that are present and identified in various crop varieties or wild relatives. This is most commonly overcome by:
| 1. | Inducing mutations | 2. | Somaclonal variations |
| 3. | Genetic engineering | 4. | Plant introduction |

Insect resistance in host crop plants may be due to morphological, biochemical, or physiological characteristics. Identify the correct statements:
| I: | Hairy leaves in several plants are associated with resistance to jassids in cotton and cereal leaf beetle in wheat. |
| II: | In wheat, solid stems lead to non-preference by the stem sawfly and smooth-leaved and nectar-less cotton varieties do not attract bollworms. |
| III. | High aspartic acid, low nitrogen and sugar content in maize lead to resistance to maize stem borers. |
