Table 1.

A summary of the attributes of different dominant molecular markers used in plant biology, and a relative comparison of their attributes.

Marker	PCR protocol	Genomic target	Relative cost	Dominance	Repeatability
RAPD	one-step	anonymous	low	dominant	moderate
ISSR	one-step	anonymous	low	dominant	high
AFLP	multistep	anonymous	moderate	mixed (low)	high
SRAP	one-step	coding	low	mixed (moderate)	high

Note: AFLP = amplified fragment length polymorphism; ISSR = inter-simple sequence repeat; RAPD = random-amplified polymorphic DNA; SRAP = sequence-related amplified polymorphism.
