(a) What is plant breeding? List the two steps the classical plant breeding involves.

(b) How has the mutation breeding helped in improving crop varieties? Give one example where this technique has helped.

(c) How has the breeding programme helped in improving the public nutritional health? State two examples in support of your answer.

I) Plant breeding is a technique to produce plants with desired traits.
Steps of classical breeding:
1) crossing of pure lines
2)Selection of plants with desired traits.


II) In mutation breeding genetic variations are created to produce desirable traits which are not found in parent plants.
