EXAMPLE SAS PROGRAMS FOR ESTIMATING HERITABILITY AND ITS STANDARD ERROR


Example SAS codes correspond to J.B. Holland, W.E. Nyquist, and C.T. Cervantes-Martinez, "Estimating and Interpreting Heritability in Plant Breeding: An Update," submitted to Plant Breeding Reviews.  Manuscript available on request: james_holland@ncsu.edu.

Choose from three different examples for heritability estimation using REML:

1. Heritability based on inbred lines evaluated in replicated, multi-environment trials. (Appendices 1 and 2 from the manuscript)


2. Heritability estimation of two different populations simultaneously from a single experiment. (Appendix 3 from the manuscript)


3. Heritability based on regression of F2:3 progeny means on individual F2 parents and based on variance among F2:3 families evaluated in an unbalanced, multi-environment trial. (Appendix 4 from the manuscript)
