Inheritability of number of fertile tillers per plant in spring barley hybrids

Margarita Gocheva, Darina Valcheva

Abstract: The aim of this study was to clarify the genetic nature of the source material and to determine the type of inheritability of the trait productive tillers per plant for spring barley hybrids. In each of the three years were conducted 30 diallel crosses. As parents were used six accessions of spring barley. The results from the study provided broad information about the genetic control of the trait number of fertile tillers per plant. The trait has been found to be controlled by a genetic system where the dominant action of genes outperforms the additive and is of greater importance for inheriting the trait.
