Bernard.North America is home to only a few of our major food, feed, and fiber crops. The centers of origin or diversity of most crops important to U.S. agriculture occur on other continents, in countries whose geopolitical ideologies may contrast distinctly with those of our nation. The crops underpinning the U.S. agricultural sector are continually at risk from insects, diseases, and physical stress. The stability of the U.S. food system would be compromised without new sources of resistance to pests and stress, which would be a detriment to domestic consumers and our export customers abroad. Plant introductions, often discovered and collected by plant explorers in the remote and desolate primary and secondary centers of origin of major crops, are a principle lifeline of new genes for pest and stress resistance. Additionally, plant introductions are sources of new genes for nutritional quality, carbohydrate and oil content, fiber characteristics, and adaptation. This volume, the second of a two-part series, chronicles the importance of plant introductions to cultivar development of U.S.CSSA special publication ;Number 17, 20.Plant introductionUnited StatesBotany, EconomicPlant introductionBotany, Economic.581.6Shands H.
