The aim of present investigation was carried out to study genetic variability of quantitative and qualitative parameters. The populations from SL-2 were characterized of higher significance on seed oil （23.74%） and protein content （16.74%）. The estimation average value of seed protein and oil content was 15.52% and 23.48% respectively. The variability of plant height ranged from 182.33 cm to as much as 200.89 cm, while distinction＇s between them were ＋ 18.56 cm which was a significant higher at P〈0.05 probability level. The SL-3 showed the higher value of HWK （34.6 g）, head per plant （39.33） and head diameter （9.5 cm） but, was characterized significantly lowest on seed protein content （13.99%）. The all traits included in our investigations showed a higher genetic variability with majority of extreme values. The sunflower populations differed significantly in several parameters measured, they have a different genetic and morphological backgrounds. Results from wild sunflower form indicated notable differences in dispersion of important genes for different traits and showed the potential for using in future for breeding program.展开更多
