Inheritance of some yield components in sunflower

In order to study the mode of inheritance and gene effects for seed set, autofertility and self-fertility, half diallel crosses with five divergent sunflower inbred lines were made. The effects of additive, dominant and epistatic gene effects were investigated by the generation mean analysis method related to parents and their progenies (F1, F2, BC1 and BC2). Seed set was determined by the most dominant gene effects. Additive gene effects were predominant in the inheritance of autofertility and self-fertility
