| Consider the following statements with reference to hybridisation in crops. |
| 1. Only way of incorporating desirable characters into crop varieties is by hybridisation. |
| 2. Hybridisation refers to crossing between genetically dissimilar plants. |
| 3. This crossing may be intervarietal (between different varieties), interspecific (between two different species of the same genus) or intergeneric (between different genera). |
| Which of the statements] given above is/are incorrect? |
A) Only 1
B) 2 and 3
C) 1 and 2
D) None of these
Correct Answer: A
Solution :
[a] Desirable characters can be introduced by genetically modifying the crops too. One way of incorporating desirable characters into crop varieties is by hybridisation. So, the Statement 1 is incorrect. Hybridisation refers to crossing between genetically dissimilar plants. This crossing may be intervarietal (between different varieties), interspecific (between two diffeient species of the same genus) or intergeneric (between different genera). Another way of improving the crop is by introducing a gene that would provide the desired characteristic. This results in genetically modified crops.
