WebAbstract. Self-incompatibility systems in flowering plants have, over the last sixty years, been repeatedly compared and classified into a remarkably consistent plan which has stood the test of time. Probably the most constant part of the plan has been the genetic control of the pollen into two distinct classes: Gametophytic, with the S gene ...
