Abstract
The present study was carried out to understand the genetic control of achene colour and shape in confectionery sunflower. F1 selfed seeds of three crosses were raised during off-season (August sowing) 2019 at the sunflower experimental area, Punjab Agricultural University, Ludhiana. In the first cross EC-734846 × EC-734849-II, the F2 ratio of black seed to white seed approximated 3:1 showing typical monohybrid segregation while the back cross with recessive parent revealed typical 1:1 segregation. The F2 progeny of the second cross EC-734863-II × EC-734846, comprised of grey seeds with white stripes, greyish black and white seeds with black stripes colour seeds exhibiting supplementary gene interactions (9:3:4). The results suggest that black seed colour is dominant over white seed colour and exhibits simple inheritance, while distinct markings on the seeds are two genes controlled. The F2 progeny of a cross (EC-734864×EC-734876) was raised to understand the inheritance of seed shape, exhibiting ovoid-shaped to elongated- shaped seeds in a 15:1 ratio indicating duplicate dominant gene interaction with elongated seeds being a recessive trait.
