Summary
Preliminary surveys indicate that most populations of Lupinus succulentus are genetically monomorphic for three flower color loci, viz., BB PP DD. In one small geographic area, a number of populations were polymorphic for the D/d locus. In this case, clinal variation and seasonal variation were found. The S/s locus, affecting seed coat pattern, was polymorphic in a large majority of populations and genetic variation at this locus is present in all but a very few colonies. When subdivisions of five large populations were studied, genetic differentiation was found within two of these populations. Gene frequencies tended toward the limits of zero or one in populations from relatively undisturbed sites but tended toward intermediate values in the more disturbed ruderal populations presumed to be recently colonized. It is concluded that recently colonized populations are not always genetically uniform.
