| Description |
The survey was conducted during the period 2011-2017 in IPGR Sadovo and includes 7 vegetation seasons. The object of investigation was cultivars common winter wheat grown in conditions of comparative study of second year progeny. The aim of the studywas competitive study of common winter wheat cultivars and identifying differences of seed yield in the conditions of primary seed production. For evaluating the variants and for establishing the differences between varieties in the trial were used dispersion variance analysis and was studied the influence of factors force of genotype and conditions of enviroment. The results show that common winter wheat cultivars (Triticum aestivum L.) Geya 1, Tsarevets, Boryana, Unak, Diamant and Sadovo 772 show higher seed yield relative to the standard Sadovo 1. A low variation in the average seed yield has been established of cultivar Diamant, other cultivars show high variation over 20% through years. Complex influence of factors genotype and conditions of the environment is higher, followed by single influence of conditions of the environment and the lowest is influence of the genotype, with little error of the variance. Through the analysis of agro-meteorological data for the period of crop vegetation there were registŠµred significant differences between the years of testing, because the period of investigation is big. The results are based on both complex influence of genotype of studied cultivars and conditions of the environment.
