Abstract
The results of research on the direction of creating the initial selection material of wheat soft winter adapted to the conditions of the south-eastern region of Ukraine in terms of productivity, winter hardiness, drought resistance, high baking quality are presented. The selection from hybrid populations was carried out according to the productivity of the ear, early ripeness, while attention was paid to the signs: the height of the plants, the number of developed spikelets in the ear, the graininess of the ear, and damage by diseases and pests. In the period from 2015 to 2017, the best numbers of the small competitive variety testing yielded a grain yield of 6,02–6,71 t/ha, exceeding the standard Donetsk 48 by 18,5–23,4 % (1,06–1,22 t/ha). Now in the preliminary breeding there are 6 perspective selection lines which provide a yield of more than 8,0 t/ha. Four new varieties of winter soft wheat have been created. In 2017, according to the results of the state variety testing, the examination of wheat varieties with a soft winter Chudo donetskoye, Peremoga, Igristaya, and Yuzovskaya was completed, which exceeded the standards in the Forest-Steppe and Steppe zones by 1,2–1,8 t/ha.
