In the area of plant breeding, it is important not only to preserve the seeds of the variety being cultivated, but also to preserve all its wild relatives. Explain with a suitable example.

The different varieties of plant be it cultivated or wild relatives have many important and advantageous genes.

For example: The wild varieties of cultivated plants although have very low yield but they have various resistant characters (genes) that can be introduced in other high yielding plants.

Hence, in order to store the resistant genes, it is important not only to preserve the seeds of the variety being cultivated, but also to preserve all its wild relatives.
