One of the primary tasks facing breeders to create new varieties and hybrids is the correct selection of parental forms. In the selection of spring durum wheat, it is important to select the components of crossbreeding, the effectiveness of which must be predicted by genetic analysis of the evaluation of the source material, in particular by determining the combination ability.
The aim of the study was to study the combining ability, features and nature of the inheritance of productivity elements in varieties of spring durum wheat. Evaluation of the combinatorial ability of seven varieties of durum wheat ('Spadshchyna', 'Kharkivs’ka 27', 'Kharkivs’ka 39', 'Kuchumovka', 'Zhizel', 'MIP Rayduzhna', 'Tera') was performed using genetic analysis by B. I. Hayman and J. L. Jinks. The parameters of genetic variation were determined by productivity elements: plant height, number of grains from the main spike, the number of spikelets from the main spike, the grain weigth from the main spike and its length. The research was conducted during 2016, 2017, in the laboratory of spring wheat breeding The V.M. Remeslo Myronivka Institute of Wheat NAAS of Ukraine. Hydrothermal conditions of the studied years were contrasting, which made it possible to identify genotypes with high combinatorial ability.
