  ASReml  ~  Analysing Mixed Genotype Plots

I have clonal trials where I have summed the individual surviving tree data to get stand (per ha) productivity values. Some plots are a mixture of genotypes so I have have calculated the contribution of each genotype (say 10) to each plot. In Stand-alone ASReml used [code]Genotype !G 10[/code] to read in the fractional contribution of each genotype to each plot, and then fitted Genotype (without pedigree) in the model.
It works well.
However, now I would like to extend it to mixed family plots and fit the pedigree as well.
I could extend the same logic and have fractional columns for the parents in each plot. If I extend the list of parents to all in the pedigree, then I may be able to merge the parent information with the background pedigree (although if it is a deep pedigree, then I will have many empty columns as those (grand-) parents are not directly in the data.)
[code]Parent !P !G 1000[/code]
Will that work?
Is there another way to approach the problem?
