Investigation of Yield and Yield Components in Bread Wheat Genotypes by Correlation and Path Analysis

This research was carried out at an experimental field at the Field Crops Department of the Faculty of Agriculture at Bursa Uludag University with a randomized complete block design with three replications was used during the 2014-2016 growing seasons. In the study, 12 hybrid lines and 1 control variety were used as experimental material. It was aimed to determine the selection criteria to be considered in the plant breeding studies and the performances of the wheat genotypes with correlation and path analysis. In the experiment plant height, spike length, number of spikelets/spike, number of grains/spike and grain weight/spike, 1000 grain weight, test weight and grain yield were investigated. As a result of the correlation analysis between the characteristics, it is found that there is a significant relationship between the grain yield and spike length, grain number/spike and grain weight/spike. As a result of the path analysis, it was determined that the properties with the highest direct effect on grain yield were the grain weight/spike and the grain number/spike properties, respectively
