Özet

The aim of this study was to determine relationship yield and yield components and to show efficiency of components on yield by using different statistical methods on data collected from berad wheat cultivars grown under rainfed conditions. Data of yield and yield components over the two years in the study were evaluated by statistical procedures; the correlation, multiple linear regression, path and factor analyse. Results in the study with respect to four statistical methods leaf area photosynthetic efficiency, green area photosynthetic efficiency, spike number per m(2) leaf area index, grain weight per spike and harvest index were the most important characteristics and they were highly effective on grain yield.
