Development of confectionery sunflower openpollinated varieties (OP-varieties) is a prospect direction in sunflower breeding. High price level for confectionery sunflower seeds pushes forward the breeding program. Contrary, it is necessary to offer product, meeting consumer’s expectation for large seeds, good dehulling rate, proper oil and husk content. The aim of our work is to study morphometric peculiarities of seed structure for sunflower OP-varieties of different types – oil and confectionery, and to identify the best samples for using in the breeding program as an initial material. The study was done at All-Russia Oil Crops Research Institute (VNIIMK) named by V.S. Pustovoit (Krasnodar) in 2014 and 2015. Seeds of 6 OP sunflower varieties of VNIIMK breeding were used as a material (confectionery type – Dzhinn, SPK, Lakomka, Oreshek, Borodinskiy and oil-type – Muster). OP-varieties were sown by randomized blocks with 3 replications. Every plot had 4 rows. It was shown that seeds of confectionery sunflower OP-varieties had higher values of main traits (length, width and thickness) in comparison with oil-type sunflower. Seed traits analyses allowed identifying the best confectionery samples (Dzhinn and Oreshek) for future breeding

Development of confectionery sunflower openpollinated varieties (OP-varieties) is a prospect direction in sunflower breeding. High price level for confectionery sunflower seeds pushes forward the breeding program. The aim of our work is to study dependence of main valuable confectionery seed characteristics from plant density and to identify sunflower samples, which decrease seed size at minimum level under high plant density. The study was done at All-Russia Oil Crops Research Institute (VNIIMK) named by V.S. Pustovoit (Krasnodar) in 2015 and 2016. Seeds of different biotypes of OP sunflower variety called Dzhinn were used as a material. Samples were sown with 2 replications. Every plot had 1 row. The highest yield of OP variety Dzhinn was obtain under plant density 60 000 plants per ha. 1000-seeds weight decreased with increasing plant density up to 60 000 plants per ha. Prospect for future breeding samples were identified which not decrease the level of valuable traits under higher plant density
