Studying of confectionary sunflower hybrid combinations developed on the base of general combining ability estimations, diallel analysis and topcross

In current time development of confectionary sunflower open-pollinated varieties and hybrids is one of the most prospect directions in modern sunflower breeding. The aim of our study was to evaluate effectiveness of parental lines selection on the base of diallel analysis and general combining ability estimations. Inbred lines and hybrids of VNIIMK breeding were used as a material in our study. Open-pollinated variety Lakomka was used as a standard. Both general combining ability estimation and diallel analysis on yield and 1000 seed weight allowed us to recommend lines VK-905 and VK-944 (K-4) as the most perspective parents for confectionary sunflower hybrid development. The results of testing of new confectionary sunflower hybrid combinations confirmed results obtained by general combining ability estimations, diallel analysis and top-cross.
