Abstract

Studies of varieties and lines of soft winter wheat, which were conducted during 2014-2017 in the competitive variety testing of selection crop rotation NSC "Institute of Agriculture NAAS", found, that they behave differently in the forest-steppe growing zone and when tested over the years. It was found, that the level of winter hardiness (8 points) in the experiment, in accordance with the Lisova pisnia standard, was increased in 2014. The average level of winter hardiness (7 points) in the experiment was obtained in 2015, 2016, 2017 years. In 2014-2017 from 33 varieties and lines of soft winter wheat competitive variety testing allocated 30 ranks to determine the level of yield in the Northern Forest-Steppe of Ukraine. For two years of research (2016-2017) it was found, that the yield of the line Lutescens 188-13 was 8.46 t / ha and it was classified as rank 1; line Erythrospermum 242-13 - yield 8.45 t / ha, rank 2; variety Merezhka (Dovira) - yield 8.29 t / ha, rank 3; line Lutescens 101-13 - yield 8.15 t / ha, rank 4; variety Polysyanka - yield 8.15 t / ha, rank 4; variety Spivanka Poliska - yield 8.15 t / ha, rank 4; variety Myroliubna - yield 8.11 t / ha, rank 5; line Erythrospermum 185-13 - yield 7.75 t / ha, rank 7; line Erythrospermum 176-13 - yield 7.69 t / ha, rank 9; line Erythrospermum 279-13 - yield 7.65 t / ha, rank 10; line Erythrospermum 251-13 - yield 7.53 t / ha, rank 12; line Lutescens 151-160-13 - yield 7.30 t / ha, rank 15. During three years of research (2015-2017) the yield of variety Shchedrivka Kyivska was 7.55 t / ha and it was classified as rank 11; line Lutescens 161-170-13 - yield 7.32 t / ha, rank 14; line Lutescens 171-180-13 - yield 7.30 t / ha, rank 15; variety Vodogray - yield 7.25 t / ha, rank 16; line Lutescens 197-13 - yield 7.18 t / ha, rank 18; line Lutescens 195-13 - yield 7.00 t / ha, rank 20; line Lutescens 240-13 - yield 6.99 t / ha, rank 21, line Erythrospermum 278-13 - yield 6.90 t / ha, rank 22; line Erythrospermum 291-13– yield 6.70 t / ha, rank 25; line Lutescens 238-13 - yield 6.66 t / ha, rank 26; line Lutescens 392-13 - yield 6.38 t / ha, rank 30. During four years of research (2014-2017) the yield of the variety Kpaievyd was 7.84 t / ha, it is classified as rank 6; variety Kesariya Poliska - yield 7.71 t / ha, rank 8; line Lutescens 190-13 - yield 7.44 t / ha, rank 13; line Lutescens 196-13 - yield 7.22 t / ha, rank 17; variety Pamiati Hirka - yield 7.05 t / ha, rank 19; variety Benefis - yield 6.88 t / ha, rank 23; line Lutescens 231-13 - yield 6.80 t / ha, rank 24; line Erythrospermum 355-13 - yield 6.61 t / ha, rank 27; line Erythrospermum 175-13 - yield 6.49 t / ha, rank 28; line Erythrospermum 271-13 - yield 6.45 t / ha, rank 29.The best varieties and lines of 2014 to the level of yield (9.30-6.75 t / ha, respectively, the standard of 6.44 t / ha) and valuable economic characteristics revealed Kraevyd, Erythrospermum 175-13, Caesarea Poliska, Pamiati Hirka, Stolichna, Benefis, Olzhana, Lutescens 161-170-13, Lutescens 197-13, Lutescens 190-13), Lutescens 195-13, Lutescens 171-180-13, Lutescens 240-13, Erythrospermum 355-13, Lutescens 238-13.
