Hi,

I am building grapevine high-density genetic maps based on SNPs. I have one F1 population and I am using the pseudo-test cross method.

I am trying to insert SSRs but, despite the fact that the software links them on specific LGs, I am notable to find any certain position for this type of markers. The software just aggregates them indipendently from SNPs.

I am using their physical positions but the significativity of the ordering falls down.

An idea?

Thank you very much
