Abstract

Among ten slow-growing protoclones of Agaricus bisporus (J. Lge) Imbach, all appressed colonies showed slower growth rate and spawn run, and inability to produce fruiting bodies in substrate. Seven of 40 inter-simple sequence repeat (ISSR) primers amplified 78 reproducible fragments, 48.93% were polymorphic, each producing 7 to 16 bands ranging from 0.10 to 2.10 kbp, sufficient to differentiate the protoclones from each other. Appressed protoclones were homoallelic at a number of loci that were heteroallelic in the parent, suggesting that they represented rare homokaryons. Thus, using morphological characters along with ISSR, polymorphisms could be useful for quick, easy, and accurate in distinguishing homo- and heterokaryotic isolates.
