Data from: Genetic and spatial variation in vegetative and floral traits across a hybrid zone

Premise: Genetic variation influences potential for evolution to rescue
populations from impacts of environmental change. Most studies of genetic
variation in fitness-related traits focus on either vegetative or floral
traits, with few on floral scent. How vegetative and floral traits compare
in potential for adaptive evolution is poorly understood. Results:
Vegetative traits SLA and WUE varied greatly among planting sites, while
showing weak or no genetic variation among source populations. SLA and
trichomes responded plastically to snowmelt date, and SLA exhibited
within-population genetic variation. All aspects of floral morphology
varied genetically among source populations, and corolla length, corolla
width, and sepal width varied genetically within populations. Heritability
was not detected for volatiles, due to high environmental variation,
although one terpene had high evolvability and two terpenes correlated
genetically with sepal width, associated with high emission from that
tissue. Environmental variation across sites was weak for floral
morphology and stronger for volatiles and vegetative traits. Three of 4
volatiles showed inheritance departing from additive. Conclusions: Results
indicate stronger genetic potential for evolutionary responses to
selection in floral morphology compared with scent and vegetative traits,
while finding potentially adaptive plasticity in some vegetative traits.
