A new cultivar of smooth bromegrass (Bromopsis inermis Leyss) Flagman was developed by methods of mass selection and polycross. Breeding and wild forms of various ecological and geographical origins are used as an initial material. The authors of the cultivar: Kazarinova I.N., Polyudina R.I., Straub A.A., Gomasco S.K. Studies were conducted on the Central experimental base of the Siberian research Institute of fodder crops of the Siberian Federal Scientific Centre of Agro-BioTechnologies of the Russian Academy of Sciences, located in the forest-steppe zone of Western Siberia (Novosibirsk region, Novosibirsk district, Krasnoobsk). The cultivar is mid-ripening: the period from the beginning of spring aftergrowing to mowing ripeness is 63-75 days and to full maturing of seeds is 95-111 days. The yield of dry matter is 8.3 t/ha, which exceeds the standard by 8%, seed yield - 0.62 t/ha, higher than the standard by 28%. The dry matter yield of the cultivar Flagman for the fourth year of use exceeded the standard by 23% and reached to 11.4 t/ha. The 1000 seeds weight is 3.0-3.4 g. The plant height is 90-140 cm. Tilling capacity is up to 40 stems per tuft. Foliage varies from 32 to 50% depending on the age of the grass and environment conditions. The resistance of the cultivar to brown rust and helminthosporiosis is higher than of the standard. The copyright certificate No. 71916 and patent No. 9653 were received.
