Combining Ability According to the Traits of Stem Branching and Plant Height in Linseed Lines

摘要

The combining ability according to the traits of stem branching and plant height has been studied for ten pure lines of oil flax under the conditions of complete and incomplete diallel crosses. The high heri-tability of traits, such as plant height, the number of lateral stems and shoots, and the essential role of genes with dominant effects of interaction in genetic control of the traits of stem branching and plant height have been shown. The methods of application of certain genotypes and crossed combinations in flax breeding based on combining-ability indexes were identified. Some new complexes of habitus traits and agriculturally valuable plant characteristics were obtained as a result of individual selection from hybrid combinations.
