We studied sibling family seed pod contents, seed coat color polymorphism, and seed weight and germination in order to detect whether variation exists within and among six proximate Lupinus perennis populations. Total ovules produced per pod, abortions per pod, and seeds produced per ovule differed significantly within and among populations. Seed coat color and speckling varied by population. Seed weights and germination rates also exhibited significant differences. Collectively, these differences may indicate the existence of population level genetic variation, however, phenotypic response to environmental heterogeneity may be responsible. Future experimentation quantifying growth traits, as well as genetic assaying, may elucidate this more clearly.
