Relationships among Traits Using Correlation and Path Coefficient Analysis in Safflower (Carthamus tinctorius L.) Sown Different Fertilization Levels and Row Spacing

Murat Tuncturk and Vahdettin Ciftci

Abstract:
This research was conducted out in 2001 and 2002 at Van, Edremit ecological conditions in east of Turkey. One of the aims of this research was to determine the relationship among yield and some yield components using correlation and path coefficient analysis. In this study Yenice safflower cultivar was sown at three different phosphorus levels (0, 60, 120 kg ha-1), four different nitrogen levels (0, 50, 100 and 150 kg ha-1) and three different row spacing (20, 30 and 40 cm). The experiment was designed split-split plot design with four replications. The first experimental year positive and significant relationships were found among seed yield and plant height (r= 0.385**), number of head per plant (r= 0.160*), percent of oil (r= 0.945**) and oil yield (r= 0.981**). Negative and significant relationship was found between seed yield and percent of protein (r= -0.272**) but negative and non-significant relationship was found between seed yield and 1000-seed weight (r= -0.129). The second year positive and significant relationships were found between seed yield and all investigated characters. According to path coefficient analysis, in the 2001 and 2002 experimental years there were strong positive direct effects of the oil yield on the seed yield , p.c : 1.3305 and p.c: 1.5205, respectively.
