Dear Folks

I have a trial at 2 sites of macadamia that contains both progeny
procued by crossing and clones of the parents of the progeny. We have
used trained assessors to assess a visual atribute of the kernel, basal
discolouration. We selected 550 progeny form across the 55 familes
available (i.e usually 10 progeny per family), and 5 ramets of each of
the 10 clones. 11 parents were used to make the crossings.

From each individual plants we took 2 samples of 10 kernel. Two
assessors each assessed one of the samples of 10 kernel. The trait was
assessed on a scale from 0 (absent) to 3 (extreme).

My interested is to include both plants types in the genetic analysis to
estimate both additive and non-addtive effects so I can compare progeny
performance against clonal performance. I have chated to Arthur and
Joao Costa e Silva about this last year but without the complication of
the hierarchy in the design.

I have attached the the command file and the output file.
<<>> <<bd06cs_t23_test04.asr>> I get a message that
the message is too big when I include the zipped data file. I can send
that individually if anyone wishes.

The model is

         !r ,
            AGROUP.TREE, # additive covariance matrix for both groups
            at(AGROUP,2).FAM, # to estimate family effects for seedlings
            at(AGROUP,1).ide(TREE), # to estimate non-additive variance
among clones
            PLANT, # to estimate common between plants non-additive and
non-family variance (i.e. within family VD for seedlings and E
            at(AGROUP,1).PLANT, # to estimate difference between VPLANT
and within clone variance
            PLANT.ASSESSOR, # interaction between assessor and plant
             !f mv

0 0 1 !STEP 0.1
AGROUP 0 CORGH 0.99 0.1 0.2 !GFUU # correlation =1 forces Vtree in
group,1 to be additive variance

I am getting a singularity in the analysis which may be limited data but
would appreaciate feedback about the model to see if there is somethere
I have missed.

Any coments greatly appreciated

Thanks for your time
