The development of science-based technologies of cultivation makes it possible to reveal the productive potential of new varieties of perennial grasses. In 2021-2022 in the conditions of the Penza region, there were studied the seeding rates and methods of sowing of a new variety of awnless brome Udalets when cultivated for seed. According to the hydrothermalcoefficient, the growing season of 2021 was characterized as dry (HTC = 0.8), 2022 – as normal in terms of moisture supply (HTC = 1.0). The best indicators of the development of brome plants (mass of plants and roots) by the end of the first year of life were obtained using a wide-row sowing method with row spacing of 30 cm at a seeding rate of 5.0 million viable seeds per 1 ha. In terms of the yield of green mass and the collection of dry matter from 1 m2 in the first year of life, the wide-row sowing method with a row spacing of 30 cm had an advantage. During the year of awnless brome grass use the best indicators of seed yield were obtained by wide-row sowing method with row spacing of 30 cm at a seeding rate of 5.0 million viable seeds per 1 ha. At the same time, the number of productive stems was 106 pcs/m2, the length of the inflorescence was 19.0 cm, the number of spikelets in the inflorescence was 182 pcs., the weight of seeds from a productive shoot was 0.78 g, the weight of 1000 seeds was 4.26 g, which was 8.2; 8.0; 11.0; 13.0; 0.9 %, respectively, higher than the control variant with a row sowing method with row spacing of 15 cm at a seeding rate of 6.0 million viable seeds per 1 ha. The highest seed yield of awnless brome in the first year of use was formed with a wide-row sowing method with row spacing of 30 cm at a seeding rate of 5.0 million viable seeds per 1 ha (824 kg/ha), the increase over the control was 146 kg/ha, or 21.5 %. By a row method of sowing with row spacing of 15 cm, a high yield was obtained in the control variant (6 million viable seeds/ha) – 678 kg/ha. With a seeding rate of 5.0 million germinating seeds per 1 ha, the seed yield decreased by 7.6 %.

The study of fertilizers and growth regulators in non–irrigated conditions was carried out in 2018-2020 on the basis of the Volga NIISS branch of the SamSC RAS. On average, over the years of study, there is a positive effect on the seed productivity of inoculants, growth stimulants, and complex fertilizers. Based on the analysis of indicators of productivity elements and yield data, it was found that the maximum productivity in the experiment was provided by the option with seed treatment + two–time treatment for vegetation with the addition of Mival – Agro in the budding phase - 1.95 t/ ha, which is 29.1% higher than the control. The greatest effectiveness of the preparations used was expressed in an increase in the yield of beans by 38.7%, the weight of seeds from 1 plant – 54.2%, the productivity of nodes by 44.1%, branches – 36.4%. Option 2 and 3 allowed to increase the seed yield from 1.67 to 1.78 t/ha compared to the control. The option with seed treatment with an inoculant was at the control level on average over the years of research.

The results of biological evaluation of awnless bromegrass varieties in diﬀerent agroclimatic zones of Yakutia are presented. A total of 143 collection varieties of awnless bromegrass from the genetic collection of VIR, other research institutions and local wild specimen were used in the research. The varieties studied are highly winter-hardy, the breeding specimen numbers to a greater extent. The drought tolerance of the varieties grown in the three zones of Yakutia is evaluated. A close relationship between winter hardiness and drought tolerance (water retention capacity) in awnless bromegrass was established. The correlation coeﬃcient averaged 0.74. The intensity of transpiration in awnless bromegrass cultivars is evaluated. Analysis of the daily dynamics of transpiration revealed that during the initial development phase of generative shoots (emergence into a tube), the minimum intensity of transpiration occurred in the evening and the maximum in the morning and afternoon hours. During the earing and ﬂowering phase, the intensity of transpiration depends on weather conditions. It has been established that high winter hardiness of awnless bromegrass accounts for high hay yield; low water-holding capacity accounts for winter hardiness and maximum hay yield in the conditions of Yakutia's cryolithozone. The correlation coeﬃcients between winter hardiness, drought tolerance parameters and hay yield at diﬀerent herbage levels averaged –0,85… –0,24. The standard variety of awnless bromegrass Kamalinsky 14 is stable and highly adapted to the conditions of Yakutia, and is recommended as a seed parent in the selection process for awnless bromegrass. When selecting varieties of awnless bromegrass, attention should be paid to varieties from local breeding, as well as populations of expeditionary collections across Yakutia, which have high seed yields.
