ABSTRACT
Our interest has been to use molecular genetic markers to develop an effective strategy for breeding improved strains of Agaricus bisporus Lange (Imbach) (= A. brunnescens Peck). In this review, I will first summarize some recently developed molecular-genetic markers and then describe how we are using these markers to quantify genetic variability among strains and to follow the process of inheritance in A. bisporus. Before discussing markers, however, it is important to consider the sources of genetic variation in A. bisporus upon which a breeding program can be based.
