| I: | New cultivars produced by plant breeding are first evaluated in research fields and their performance is recorded under ideal fertiliser application, irrigation, and other crop management practices. |
| II: | After evaluation in research fields, the new cultivars are tested in farmers’ fields for at least three growing seasons at several locations in the country. |

| Assertion (A): | Cross hybridising the two parents to produce hybrids that genetically combine the desired characters present in the parents is a tedious and time-consuming process. |
| Reason (R): | The desired characters have very often to be combined from two different plants [parents]. |
