DEPENDENCE OF VALUABLE TRAITS OF CONFECTIONERY SUNFLOW SEEDS ON POPULATION DENSITY
06.00.00 Agricultural sciences
DescriptionDevelopment 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
