Abstract
SUMMARYA breeding programme was initiated to develop populations of sunflower (Helianthus annuus L.), suitable for the semi-arid regions of Iran. Crosses were made between Chernianka 66 (having low yield, low oil content, short stem, and early maturity), as the female parent and VNIMK 8931 and Record (having high yield, high oil content, long stem, and late maturity) as the male parents. Selection, together with selfing and sib-crossing, resulted in six populations with high yields, high oil content, short stems, and early maturity.Correlation coefficients of oil yield and its components, i.e. seed yield and oil content, were highly significant and significant respectively. Capitulum diameter had highly significant correlations with seed yield and oil yield. Earlier maturity was associated with shorter stems and lower oil content.
