Özet: The survey was conducted during the period 2015-2017 in the experimental field of IPGR Sadovo. The elements of productivity of 29 common winter wheat varieties (Triticum aestivum L.) with origin from Belarus and two Bulgarian varieties – Sadovo 1 and Enola were studied. The coefficient of variation has been calculated and the correlation dependencies between the elements of productivity are determined. The influence of factors genotype, environment and their interaction on the studied features is assessed. A low variation in the trait was recorded in the number of spikelets per spike, spike length and number of grains per spike. With high variation is characterized the number of grains per other spikes. The strongest correlation dependence is observed between features grain number per plant with grain number per other spikes, followed by the grain weight per plant with grain weight per other spikes. The plant height is in negative correlation with all studied elements of productivity. The factor genotype has the greatest influence on the plant height and the cultivation conditions have a leading role in the productive tillering.
