[The systems of genetic control of the traits of branching and plant height in linseed].

The genetic control of the traits "plant height", "the number of lateral shoots" and "the number of lateral stems" has been studied in 3 pure lines and 1 variety of linseed according to the model 1 of Hayman method. It has been shown that the traits under investigation are inherited according to the additive-dominant model of genetic control in the absence of any interloci interactions. The higher plant height and numerous lateral shoots are recessive traits controlled by 2 blocks of polymeric genes, whereas the trait of numerous lateral stems is a dominant trait influenced by 1 to 3 blocks of genes. The linseed lines have been ranked according to the number of dominant alleles they have. Suggestions for selection using these parental genotypes have been made.
