Descriptif
Because there is evidence of systematic genetic variation according to macro-geographical areas, and even some evidence for genetic stratification in centers of genetic diversity, I undertook the present study. If genetic stratification could be associated with relatively small niches, such evidence would be useful both to the plant collector for maximizing genetic diversity with minimal samples and to the plant breeders in selecting the appropriate collections for his goals. The study was performed on Avena sterilis L., a wild relative species of oats. I used samples of this that originated from its entire habitat, and each sample was assayed for 15 traits. My specific objectives were (a) to study the genetic variability among A. sterilis samples, (b) to see if there is a particular pattern of variability for the characters, (c) if this pattern is present, whether there is a connection between geographical region and particular character(s), and (d) to evaluate the application of multivariate analysis as an aid to study the genetic variability
