Study of the correlation between the structural elements of yield in common wheat

Velika Kuneva, Antonia Stoyanova

Abstract: The aim of the study is using a correlation analysis to assess the relationship between the basic biometric parameters and the effect of treatment with some herbicide and herbicide formulation of six common wheat variety. The study was conducted at an educational-experimental field of the Department of Crop and Agricultural Faculty at the Thracian University – Stara Zagora during 2012 – 2014 in a Meadow Cinnamon Soil. A very high statistical proven correlation is established (r > 0.8) between the length of the class and weight of the grains in the class (Ingenio), number of grains and grain weight class (Ingenio) length of the class and number of spikes (variety Illico and Enola), and number of spikes in the number of grains class (variety Apolon). Statistically, correlation between plant height and other biometric indicators, and weight class of grain and weight of 1000 grains is not proven.
