Study on correlation and path analysis in F2 population in safflower

Abstract

The study was conducted during rabi 2015-16 at research cum instructional farm of IGKV, Raipur. Number of seeds per capitulam has significant positive correlation with seed yield. Similarly, number of branches per plant shows significant correlation with number of capitulam per plant. Number of seeds per capitulam also showed significant positive correlation with plant height and number of capitulam per plant. Days to 50% flowering has significant negative correlation with number of branches per plant, seed yield per plant (g) and number of capitulam per plant, respectively. Number of capitulam per plant has maximum positive direct effect on seed yield per plant followed by number of seeds per capitulam, number of branches per plant and plant height, indicated maximum contribution of these traits in seed yield.
