Title:
 Logistic model in analysis of two– and six–rowed spring barley doubled haploid lines (Hordeum Vulgare L.)

Language: English

Summary:
The object of investigation constituted forty doubled haploid (DH) lines of spring barley (Hordeum vulgare L.). The DH lines were produced from seed of F1 progeny obtained after crosses of two– and six–rowed cultivars. The control group (without use of mutagen) and the group with use of mutagen include twenty DH lines. In the both groups fourteen lines were two–rowed forms and six were six–rowed forms. Doubled haploid lines were analyzed with respect to the number of spikes. The considered trait is treated as discrete, so in the analysis the logistic model which belongs to the class of generalized linear models was applied.
