Abstract

Introduction: Reproductive systems have a profound effect on the genetic structure of plant populations. How genes are passed from one generation to the next influences the amount and structure of genetic variation in succeeding generations (Clegg, 1980; Bell, 1982). Sexual reproduction increases the genetic variation within a population through recombination while asexual reproduction duplicates the maternal genome (Williams, 1975). A variety of systems have evolved in plants which combine both sexual and asexual reproduction (Lloyd, 1984 ).
