✦ Synopsis

Interactions of seven bio-morphological characteristics of sunflower (head diameter, number of flowers per head, number of seeds per head, 1,000-seed weight, volume weight, kernel content in seed, oil content) and their correlations with seed yield per plant were examined . The path-coefficient analysis provided information about direct and indirect effects of the examined characteristics on seed yield per plant . The correlation coefficients were positive and highly significant . The highest direct positive effect on seed yield per plant was exhibited by the weight of 1,000 seeds . Head diameter, volume weight and kernel content had a direct negative effect on seed yield per plant .
