| description | Ear emergence time (EED) in winter wheat directly affects its ability to adapt. Its change affects the grain yield similar to its components. The aim of the study was to analyze whether the change of date of ear heading has an effect on the elements of productivity and grain yield in contrast to the growing environments. Data were collected for analysis of test 30 varieties of winter wheat in the 4-years period in five locations of the country. The performance of individual traits is estimated by different statistical approaches to study the most detailed correlationships between them. The variation of the characteristics in terms of experience in these conditions characterized by contrast. Under normal and accidental changing growing conditions, resulting in season points and testing found positive influence on later date ear heading on the yield of grain. Between the EED and components of productivity there are positive correlations that are reliable even against the contrasting conditions. Changing this trait reflects fairly heavily on the characters associated with the number of grains in spike and per unit area, too. Characters that directly determine the level of productivity in winter wheat are strongly influenced by environmental conditions and genetics of participating in the experiment varieties. |
