Summary The crop domestication process is examined from plant collection to product release for various junctures at which deliberate breeding, selection, and crop transformation may occur to prevent invasive potential. Four primary juncture opportunities for research on techniques and development of selection procedures for non-invasiveness include: The Plant Exploration Phase, Initial Trial Phase,...
Summary Imperfect scientific information regarding potential invasiveness, differences between private and public outcomes for individual decisions regarding planting, and inadequate prevention activity combine to impose costs through a change in native ecosystems susceptible to invasion by hardy, rapidly reproducing non-indigenous species. Concepts and tools from economic theory that may improve...
Summary The invasive potential of a species can be assessed by propagule pressure, which measures the chances for propagules of a species to find a suitable habitat for establishment and reproduction. Seeds, fruits, and vegetative structures that contribute to the propagule pressure are morphologically, physiologically and genetically different from one another, thus each kind should have a specific...
Summary In plant breeding programs, qualitative and quantitative traits confer market value and, thus, constitute the basis for developing breeding criteria during crop domestication. Some traits such as high male/female fertility are advantageous in the wild and could enable the evolution of cultivated crops into invasive weeds. Other traits, e.g. sterility, are not expected to confer invasiveness...
