  1. Introduction Conservation of plant genetic resources differ depending on whether they are approached using in-situ and ex-situ approach at the North Central Regional Plant Introduction Station accessions and compared it with my in-situ accessions back home in New Mexico. Ex-Situ Conservation – The Genebank The ex-situ conservation involves maintaining varieties off site. Its purpose is to protect the species (maize) outside of the natural habitat. NCRPIS is a crop genebank that conserves crop plants and their wild and weedy relatives using the ex-situ conservation. In-Situ Conservation–Within Culture Approach The Navajo corn that is traditionally grown in an example of in-situ conservation of landrace crop plant. In-situ conservation protects the cultural tradition that the variety was developed in thus conserving biodiversity.

NC7 staff member working in cold storage vault Aerial view of the Plant introduction farm Corn field in NM Conclusion In conclusion, after comparing and contrasting the corn from the Navajo reservation and corn from plant introduction station they have variation changes from corn yield to pollination. This is good in several different ways because it preserves the meaning of in-situ conservation and ex-situ conservation. Compare and Contrast References and Acknowledgments Kiesselbach, T.A.
