Rauf, A: Genetic Studies Of Sunflower (helianthus Annuus L.)

A greenhouse and field research was conducted to evaluate twenty accessions for genetic potential and path coefficient analysis under salt stress and normal conditions for various plant traits in sunflower.The experiment was conducted in completely randomized design with three repeats. The results suggested that expression of all traits were reduced with increase the salt stress levels.The accessions G-36, G68, A-23, G-61 and A-185 showed significant and positive results for all traits with biomass under all salt stress levels. The yield experiment was conducted in randomized complete block design and the results showed the highest positive correlation with total achene weight was shown by 1000 grain weight and oil content and highest positive direct effect on total achene weight was shown by oil content, fresh head diameter, plant height and days to 50% flowering. The accessions G-64 and G-36 showed significant and positive correlation with yield.
