A case of functional male sterility in Solanum insanum L.

摘要

Plants from over 60 collections of S. insanum, a weedy relative of aubergine (S. melongena), were evaluated for vegetative and reproductive characters. A plant was detected with indehiscent anthers. It showed regular bivalent formation during microsporogenesis, high pollen viability, and normal fruit and seed set following artificial self-pollination. But the anthers did not dehisce and the pollen grains degenerated within the anther locules.
