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.

(N/A) In the area of plant breeding,it is important to preserve both the seeds of cultivated varieties and their wild relatives because wild relatives often possess valuable genes for resistance to diseases,pests,and environmental stress.
While cultivated varieties are selected for high yield,they may lack these protective traits.
By preserving wild relatives,breeders can introduce these beneficial resistant genes into high-yielding cultivated varieties through hybridization.
For example,wild species of wheat or rice often contain genes for resistance to specific pathogens that are absent in modern high-yielding varieties.
