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.
Preservation of the seeds of the cultivated variety and its wild varieties helps in making a good germplasm collection. Selective breeding of plants has produced many high-yielding and disease-resistant varieties of wheat, rice and maize. A better germplasm collection makes this possible. The modification of plant species to produce new, improved kinds that are more suited for cultivation, produce more, and are resistant to pests and diseases is known as plant breeding.
