Direct and indirect responses to selection on pollen size in Brassica rapa L

Direct and indirect responses to selection on pollen size in Brassica rapa L

Journal of Evolutionary Biology 14(3): 456-468

Pollen size varies little within angiosperm species, but differs extensively between species, suggesting the action of strong selection. Nevertheless, the potential for genetic responses of pollen size to selection, as determined by additive genetic variance and genetic correlations with other floral traits, has received little attention. To assess this potential, we subjected Brassica rapa to artificial selection for large and small pollen during three generations.
