ABSTRACT
Correlation studies in safflower revealed that seed yield was positively associated with yield components. Among yield components, correlation of biological yield per plant was maximum followed by number of effective capitula per plant, total capitula on primary branches, plant height, number of seeds per capitulum on primary branches and number of primary branches per plant. Correlations among yield components were positive, encouraging rapid improvement of yield. In present investigation, the value of correlation was less than one in all cases which is an indication of lesser effect of environment. Path coefficient analysis showed that the direct effect was maximum for days to maturity followed by plant height and number of effective capitula per plant. The maximum indirect effect for any character was through days to maturity. In present investigation path coefficient analysis was not much reliable due to greater environmental effect on variance and covariance. However, it was observed that days to flowering and days to maturity were mainly influencing the seed yield per plant in positive and negative direction respectively. It can be concluded that direct selection is most effective for seed yield per plant. However, to improve yield indirect selection for days to maturity (late maturity), plant height and number of effective capitula per plant could be utilized for further breeding purpose.
