Summary. Varieties Krastal and Chernozyomka 115 are created by a method of difficult, step hybridization. They are included in the State register of the selection achievements allowed to use. The maximum productivity of a grade of Krastal (selection of line Lutescens 1723 H 260) is 8, 78 t-ha at the state test. The variety is characterized by high resistance to drowning. Winter hardiness and drought resistance, resistance to a damping-off and frosts of this grade and the standard are at one level. In the Central Black Soil region Chernozyomki 115 (Lutescens 1723 H 260 × Dokuchaevskaya Yubileynaya) average productivity was 3, 85 t-ha during the years of a state test, and maximum – 9, 07 t-ha. It is mid-season variety. Winter hardiness is higher than average, it exceeds the standart Odesskaya 267 at 1, 0 point in a year of display of a sign and is at the level of Lgovskaya 4. Height of plants is 70…104 cm, they are steady against drowning. It exceeds Moscovskaya 70, Odesskaya 267 and Lgovskaya 4 on drought resistance on 1, 0…1, 3 points. It is valuable wheat on a complex of indicators of quality. It possesses moderate resistance to leaf rust. In the field, as Bezenchukskaya 380, is affected by powderi mildew weakly. The variety Laguna (Dokuchaevskaya Yubileynaya × Donskaya Niva) is transferred to the state test in 2011. Average productivity of a grade is 5,87 t-ha in a competitive grades testing, this indicator is higher than the standard Tarasovskaya 29 on 1,55 t-ha (35,9 %), and maximum – 6,97 t-ha (73,8%). Chernozyomka 121 (Lutescens 1305 × Lutescens 1292) and Chernozyomka 130 (Lutescens 1292 × Lutescens 1412) were received from crossing the selection lines created in local climatic conditions among themselves and were transferred to the state test in 2013. Both new grades exceed the standard on productivity for 37,1 and 41,3 % respectively.
