variability as well as true genetic differences. This, however, does not invalidate the mass screening process but rather results may be specific to only one or a few plants within an accession (as opposed to a more uniform response that might be expected in a

cultivated varieties of C. frutescens have occurred largely as a result of human selection within existing varieties, and limited information is available in the scientific literature regarding variability for agronomic or horticultural traits within the

-Alcazar, 2005 ; Tanksley and McCouch, 1997 ) have led to the need to preserve as much genetic diversity as possible both in situ and ex situ not only for the long-term survival of the species, but also to have enough variability available for breeding programs

study investigating the genetic diversity in two other intermountain Allium species also found a high degree of within-species genetic variability not only in the narrowly restricted species ( A. aaseae ), but also in a widespread congener ( A

approaches to assess variability in clonal plants have been reported, but indistinguishable morphology has been difficult to characterize. Molecular markers have the ability to detect genetic variation and provide a reliable method to ensure the integrity of

variability on maps enable the user to characterize an AVA for any or all of the environmental factors represented by dynamic layers, and to examine spatial relationships among factors. AVATXIS was used in this way to extract spatial environmental data to
