Mechanisms of interspecific incompatibility in tuber-bearingSolanum species

  • Published:
American Potato Journal Aims and scope Submit manuscript

Summary

The failure to produce seeds following interspecific crosses of tuber-bearing species ofSolanum was found to be due to three causes: (1) pollen tubes were inhibited in the style so fertilization was not effected; (2) fertilization took place but the ovary failed to develop; and (3) fertilization was followed by complete abortion of all embryos at an early stage in their development.

Crosses in which the various mechanisms leading to a lack of seed formation that were encountered are listed in this paper.
