The paper presents numerical comparison of two methods of estimation of nonallelic interaction of QTL effects. In the first method we assume that we observe only the plant phenotype, while in the second method we have additional information from the molecular markers observations. In this paper we analysed phenotypic data on 120 barley doubled haploid lines, derived from cross Clipper × Sahara and data concerning 183 molecular markers. The analysed traits were beta-amylase activity, alpha-amylase activity, betaglucanase activity and cyst nematode resistance. Results obtained for three from four traits show that by using molecular marker observations we obtain estimators that have smaller absolute values than estimators obtained by the phenotypic method. |
