Fast resolution of identification problems in seed production and plant breeding using molecular markers

Polymerase chain reaction (PCR) analysis with specific and arbitrary primers was used to identify germplasm from a barley breeding program. Through practical application of the technology, an F1 plant\u27s identity was confirmed, the correct pedigrees \u27of 2 incorrectly labelled F2 populations were determined, confusion in the identity of seed lots of an advanced breeding line was resolved and off-type barley plants were identified in a seed increase block. This illustrated the value of PCR-based genotype analysis in plant breeding programs
