Abstract

Correlation studies in sunflower revealed that seed yield was positively associated with yield components. Among yield components, correlation of number of filled seeds per head was maximum followed by head diameter, total number of seeds per head, plant height and 100-seed weight. Path coefficient analysis showed that the direct effect on seed yield was maximum for 100 seed weight followed by number of filled seeds per head. The maximum indirect effects for characters were through number of filled seeds per head and 100-seed weight, those themselves were also major direct contribution of seed yield in sunflower.
