A model and estimation procedure is presented to estimate breeding values. Algorithms for Sparse QR-factorization on the CRAY X/MP are derived and implemented. Finally an adapted ordering is found, which has some advantages compared with minimum degree ordering. The fill-in for practical problems could be computed explicitly for a large part of the algorithm. The nonzero structure of the R-factor of a practical example is supplied.
