ABSTRACT
The purpose of this research was to evaluate phenotypic correlation coefficients between seed yield and some yield components and to determine the direct and indirect effect of 9 components on seed yield in sainfoin (Onobrychis sativa L.). The research was conducted at the Agricultural Research and Experiment Center of Agriculture Faculty, Uludag University in 2000-2003. The field experiments were established in a split plot design with four replications. Seed yield, plant height, raceme number per plant, stem number per m2, raceme number per m2 , fruit number per raceme, fruit weight per raceme, fruit number per plant, fruit weight per plant and 1000-fruit weight were determined. The data obtained over 3 years were combined. According to results of this research, seed yield was positively and significantly correlated with raceme number per plant (r = 0.266**), fruit number per raceme (r = 546**), fruit weight per raceme (r = 538**), fruit number per plant (r = 0.495**), fruit weight per plant (r = 0.490**) and 1000-fruit weight (r = 0.602**), while seed yield was negative and significantly correlated with stem number per m2 (r = -0.353**) and raceme number per m2 (r = -0.305**). Path coefficient analyses revealed that fruit number per plant (2.2757 and 28.50%) had the highest positive direct effect, followed by fruit weight per raceme (1.6989 and 20.74%), on seed yield, while fruit weight per plant showed the highest negative direct effect (-2.3369 and 28.59%).
