In so doing, the workshop provided an opportunity to reexamine a key issue related to the responsible development and use of agricultural biotechnology products. The workshop focused on seven groups of crop species that have weedy relatives in North America: berries, certain grains and grasses, poplar, sunflower, squash, and Brassica species.en-USCreative Commons Attribution 3.0 United StatesPest resistant cropsAgricultural biotechnology productsBerriesGrainsGrassesPoplarSunflowersSquashBrassicaBook
