The trial was carried out on the field from IPGR, Sadovo, during the period 2017-2019. The test was performed by means of a block method with four repetitions; experimental field area - 10 m2 after leguminous predecessor. The aim of the study of the study was to establish the mass of 1000 grains, hectolitre mass, plant height and yield from 31 lines and candidate varieties obtained by the method of the variety and remote hybridization were tested. In the experiment were involved two standard varieties - Sadovo 1 and Enola. The adopted in IPGR - Sadovo technology for growing of winter common wheat was used. The grain yield is determined with standard grain moisture of 13%. The indices; thousand kernel weight (g), test weight (kg), and grain yield (kg/ha) were determined. Data obtained for the plant height, the grain yield and the physical properties of the grain were statistically processed by the method of dispersion and correlation analyses. The results show: environmental factors have the most influence on the grain yield, 1000 grain wеight and test weight; was found that the plant height is significantly influenced by the genotype. The highest average yield for the period is reported on the lines МХ 286-1777, МХ 258-3355 and candidate variety Yilzla.
