Abstract
The experiment was conducted to determine the relationship among yield and some yield components using correlation and path coefficient analysis. This study was performed under Mardin conditions the years of 2011–2012 and 2012–2013. Fifteen bread wheat varieties were used in the experiments. The randomised complete blocks design with 3 replications was used. The characteristics such as plant height, spike height, numbers of seed per spike, seed yield, harvest index, biological yield and 1000 seed weight were investigated in the study. Positive and statistically significant (p < 0.01) relationships were determined between seed yield, spike height, numbers of seed per spike, biological yield and harvest index. According to path coefficient analysis, there were strong direct effects of the biological yield and harvest index on the seed yield, p = 0.53549 and 0.548321, respectively. The results of this study indicate that numbers of seed per spike, biological yield and harvest index affected seed yield and it was concluded that these characters should be considered as significant selection criteria in wheat breeding for yield under the regional conditions of southeast Turkey. © 2017, Scibulcom Ltd.
