Abstract

The aim of the research was to evaluate new promising varieties of soft winter wheat breeding of NSC "Institute of Agriculture of NAAS" for grain yield, winter hardiness, disease resistance and grain quality. Experimental studies were conducted in 2016-2020 at the NSC "Institute of Agriculture NAAS". The plot area was 20.0 m2 , repeated four times. Field, measuring and weighing, laboratory and mathematical and statistical methods were used during the research. In 2018-2020, new varieties of soft winter wheat Krasunia Poliska, Mokosha, Pyriatynka, Fortetsia Poliska, Efektna and Zemlerob were transferred to the Ukrainian Institute of Plant Variety Examination for qualification examination. use as parent components of varieties and lines of local and foreign breeding. All varieties are drought-resistant, resistant to lodging, germination on the stump, shedding of grain. The highest grain yield was obtained in the variety Fortetsia Poliska - 7.31 t / ha. Pyriatynka and Zemlerob varieties with indicators of 7.10 and 7.06 t / ha, respectively, were distinguished by high yields. By increased winter hardiness can be distinguished varieties Pyriatynka, Krasunia Poliska, Mokosha and Efektna with a mark of 8.0-8.2 points. As the most resistant to powdery mildew are selected varieties Efektna, Lisova Pisnia, Pyriatynka and Fortetsia Poliska (lesions - 1.7-11.6%). In terms of resistance to brown rust, all varieties showed high resistance, the damage did not exceed 8.0%. The greatest resistance to septoria of leaves is defined in a grade the Farmer. The highest protein content was determined in the grain of Efektna, Mokosha and Krasunia Poliska varieties (up to 11.67%). According to the increased content of gluten, the varieties Krasunia Poliska, Lisova pisnia, Mokosha (19.22-19.66%) were distinguished. According to the highest sedimentation rates, the varieties Krasunia Poliska, Pyriatynka and Mokosha should be noted (34.50-34.84 %)
