The present investigation was taken up with the primary objective of evaluating 63 sunflower genotypes including 60 inbred lines and three checks for autogamy, genetic variability, character association, path analysis and genetic diversity for seed yield and yield components. Autogamy studies revealed that hybrids recorded high per se autogamy and geitonogamy ...
