The nature of variability and inheritance of the traits of self-fertility and bee attendance of sunflower

The researches were conducted in 2006-2008 at the Central experimental station of VNIIMK named after V.S. Pustovoit. The variability of traits of self-fertility and bee attendance of varieties, hybrids and self-pollinated lines of sunflower was studied. It was determined that the variation of bee attendance trait by year is more than 2 times higher than the variation of self-fertility trait. The specific reaction of certain variety samples by variability of these traits depending on the weather conditions was noted. The inheritance of traits of self-fertility and bee attendance is of complex polygenic nature.
