Abstract
Variation in plant defensive profiles can be affected by environmental factors, genetic fac-
tors, and their interactions, and different feeding guilds may have different responses to vari-
ation in defenses. Here we present results of a factorial breeding design in Lupinus arboreus
from three sites of origin to determine how parental effects, population differences, and
environmental effects influence alkaloid profiles and resistance to multiple herbivores. Alka-
loids were identified and quantified in seeds and adult plants grown at each of the three
